This post will be a double post as this post will serve both my Wild Hawk blog and RC Flying Fun blog. How you ask? Well, I found a new place to fly and I flew my Wild Hawk for my first outing at this location. This is also the first time flying for me in several months. Wow, a person can sure get rusty! This new location is on a road stub near an abandoned mall construction site. This road stub is off of the main road and across from the abandoned mall. It is also surrounded by farm land used for growing hay. There is a small group of flyers that get together each Sunday at this location. One of the best features of this location is that it is only about ten minutes from my house.
why did I pick a place like this instead of a formal club with a real runway and amenities. Well, I already joined the AMA (I recommend this membership for everyone in this hobby) and money is really tight right now (you folks with kids in college know what I'm talking about). So funding my hobby and paying club dues and AMA dues is out of the question. This site fits my budget and still gives me a good group to associate with.
Any way, here are some photos of this location including pictures of my Wild Hawk airplane getting ready to fly.
I did have an accident and crashed hard after failing on an outside loop.
It looked bad but I was up and flying again after some minor repairs and a battery swap.
I flew all three of my batteries this day. The only unfortunate thing was that on this day there were no other flyers that showed up. I had a good time anyway and could fly and land anywhere I pleased.
Before publishing this post I got a chance to fly again and made a video from one of my flights. Enjoy this areal look around.

There are people who have expressed an interest in how to best setup their Wild Hawk out of the box and there are those who complain that their Wild Hawk is a piece of crap and does not fly. The information that both people need is the same. There are several configuration updates of a stock Wild Hawk that are important to make it the good flying plane that people love.
This is what I would do to setup a brand new, out of the box, Wild Hawk:
Glue tail surfaces
While the double face tape used to secure the tail surfaces on the Wild Hawk is adequate and will hold the parts together for quite some time, it will come loose. My recommendation is to just glue it up from the start and don't risk them coming loose in flight (yes, I have experienced this).
This shows the elevator flush with the end of the tail spar.
The first thing that needs to be done is to remove the double face tape. If you skip this part, you risk your parts coming apart as your gluing will only be as strong as the tape. Taking the tape off is not easy, but can be done with just your fingers. Using tweezers would probably make this task much easier. Now that all of the tape has been removed, its time to glue things up. It's important to glue the elevator in first and them add on the rudder. Take your time with this step and make sure the parts line up. The elevator should line up at the tail end and not the front edge like it might seem. If you don't line it up this way, you will risk the movable surfaces hitting they tail spar and not moving properly.
Re-position the battery
I don't know if it can be clearly seen in this photo, but the battery
us upside down. It will be rotated counter clock wise and slid
forward as far as possible.
This modification require the removal of the foam ridge at the forward most edge of the battery. This piece of foam it not that easy to remove but it can be done without too much trouble. Once this is removed, the battery can be placed back in upside down and with the power wires still in the side cut out for them. Since the Wild Hawk is notoriously tail heavy and does not have a proper center of gravity (CG), this is the minimum that must be done to make this plane flyable. This does not resolve this plane's CG issues, but give you a good head start.
Don't install the landing gear
While you're learning, you will not need the landing gear. Don't even bother installing them, they will just get in the way. Just make sure that you are flying near a nice grassy area and learn to belly land your Wild Hawk there.
Tape up fuselage
This is an important step to help make sure that your Wild Hawk is as rugged as possible. I have a whole post dedicated to this and it can be seen here: How to tape a Wild Hawk
Tape up wings
This is another important step as well in making sure that your Wild Hawk is as rugged as possible. This step is also covered toward the end of the above blog post link.
Balance for CG
This is an important step in making sure that your Wild Hawk is as flyable as possible I like my Wild Hawk leaning toward the nose heavy side and so I have my plane setup to balance at about 2 1/4 inches from the leading edge of the wing. This is my CG and is just forward of the embedded wing spar. A lot of people have theirs set for a CG of 2 1/2 to 3 inches from the leading edge. This will require the addition of weight to the front of the plane. I started by literally taping washers to the nose of my plane. This worked fine and has worked fine for others that I know. I decided to do something that I felt would be better and more permanent for mine. What I did was to tape fishing split shot to my plane nose until the CG was right again. Then I used my solder iron to melt some holes into the nose to hold the split shot. When this was all in place, I used hot glue to secure it all. I have a post here that shows how I did this: Weighted Question. This post shows how I made a CG finder: CG Finder
Now your Wild Hawk should be very flyable and ruggedised. If after all of this you are having issues flying this plane, the problems are not with the plane.

For all of you who think you can't fly a foamie in the wind, let alone a Wild Hawk, I'm here to tell you you're wrong!
I had the opportunity to go out flying with my Dad (for my birthday,thanks Honey) this past March 10. I like to go to his place because he has a really nice park to fly at, with lots of room and either dirt or paved areas to use as runways. The week up until then was beautiful and really fooled us that the weekend would be great also. Well, by the time we got there, the wind had really picked up. We waited around his place doing misc. fixes and playing with other stuff hoping that the wind would calm down. No such luck! We decided to just go and see what would happen.
We got there and I think the wind was worse. Easily a 15mph steady wind with gusts from 20 to 25mph! There was another person their flying a 40 class Cessna style plane, and struggling with it. He soon landed and started to pack up.
I decide what the heck, I'm here to fly and I'm gonna fly!
Now my plane is a bit modified with substantially more power and equipped with ailerons, and that really helped my confidence. (Click on some of the pictures for a link to the item I added)
So I took out my Wild Hawk and struggled to get the wings on without them being blown out of my hands by the wind. I got everything together and walked out a ways from our cars and set the plane down facing into the wind. We were all worried that the wind would blow it away. A test bump of the throttle showed that it would push into the wind. I sent the plane off and it popped right up into that head wind. I flew full power and my Wild Hawk had no problems climbing. It did take a lot of aileron to keep the plane level and to keep it's heading as the gusts really bounced it around, but it flew.
I made many passes flying full power into the wind and then shutting down the motor while banking over to let the wind take it. I would let it cruise by with little to no power and then bank it over again with full throttle.
Considering the wind, my beat up and mended Wild Hawk flew like a dream. I even did many touch and go landings with now crashes!
I really had a good time! Easily one of the best times flying yet.
Servos connect to the fuselage
I do have to admit that I did crash twice. The first time I came in too low and turned the wrong way with the wind and ended up cartwheeling the plane. No damage though (thank you tape)! The next crash was kind of crazy. Some how a gust of wind moved the wing enough to pull out one of the aileron servo connections and I could only bank one way, the wrong way! I ended up out of control in a kind of death spiral and into the group watching! Fortunately there were no injuries, and the spectators were OK too.
I had hoped to post some videos of this but my little video recorder was on the fritz and I got no usable video at all. That was a real bummer. I am posting this video because it is the same site and it too was a bit windy, not as much but fairly steady 7 to 10mph with gusts to 15mph.
So, If any one says that you can't fly a Wild Hawk in the wind because it's a foamie, send them to this site and I'll set them straight!

As you know, if you have been keeping up on my posts, that I have been trying to get used to using the landing gear on my Wild Hawk. In using the landing gear, I have noticed that the wheels do not work very well on the rough surfaces that I have as runways. My Dad's place has a lot of grass, dirt, and gravel. While my landings have been successful on these surfaces, the wheels really plow in the gravel and dirt and catch on the grass.
So I decided to change the wheel size in the hopes that it will help ease landings and take offs. Because I did not want to wait, I went down to a local hobby shop and purchased a nice pair of 2 1/2 inch diameter wheels. They are light weight plastic rims with foam tires and almost as light weight as the original ones are. At least they do not seem to weigh that much more.
Carefully twisting off retainer
Comparing old and new wheels
It did not require too much effort with a pair of needle nose pliers to take the retainers off of the axles. I did take care to not damage them as I did not have anything readily available to replace them if the would not go back on.
Close up view
How it looks on the plane
The new wheels had slightly smaller axle holes and so I needed to do some reaming and working on them to get them to go on. They go on alright now, but they only just barely spin without too much effort. This should have gone better, but I could not find the needed drill size in my tool box. I could have used some sand paper on the axle, but I couldn't find that either. Oh well, close enough.
Now it's of to some test flights, or take off and landings.

After my last flying experience with crashing my father in-law's Wild Hawk, I needed something to redeem myself. As chance would have it, the following week was beautiful flying weather and my father in-law had repaired his plane, so I worked on scheduling another outing over the weekend.
When I woke up on Saturday, the wind was blowing like a tornado! No flying today and most likely not tomorrow either. It looked like it would be another week before we would have an opportunity to fly, and me an opportunity to redeem myself.
Amazingly, Sunday morning was as calm as could be. Perfect flying weather! I quickly scheduled a time with my father in-law to go flying. He picked me up on time and we headed to the flying field. And by flying field I mean the open field near my house. We quickly but carefully unloaded our planes from his car.
I noticed that my father in-law had done a great job of hot gluing his plane back together. It looked great! Everything was straight and clean. You could hardly tell that I had crashed it and broken the whole nose off. We were too anxious to get out and fly so I forgot to take any before photos.
After several unsuccessful attempts to launch his Wild Hawk himself (short runs into the ground, but no damage!) he asked me if I could try. The pressure was on to not crash and destroy his plane again!
I was in luck and his plane took to the air beautifully! The pressure was coming down. It took a bit but soon enough I had it trimmed out and flying around nicely. I handed the controls back and my father in-law flew the plane for a minute or so before getting into trouble and handing the controls back. I regained control and handed the transmitter back to him again. He was flying around nicely and then started to bring it down some. Before we knew it, his plane was headed to the ground without enough time to hand me the controls. I have to admit though, that I don't know if I would have taken the transmitter back this time so as to not be the one to crash it again.
Well, even from where we were, we could see parts fly when it his the ground. Ouch!
Here are the pics I did take of the results.
Father in-law headin out to the crash site.
He's there, look close.
The gear and most importantly, the coffee.
The plane without the damage is my plane.
Yeah, bad crash
Ewe, wing arch is separated too
The tape did not help much this time
Well, my father in-law has shown that he is really good at fixing planes so I'm sure that he will have this one flight ready soon enough.
I hate to say this but I flew my plane from ground take of to landing with no issues what so ever.

Hello all, I discovered that my new Wild Hawk motor is not performing as well as I expected. I wondered why and after some research I found that others who had made similar modifications also upped the prop size from the stock 5x5 to 6x4 to 6x5. So, that is my next update.
Ok, ok, I know that the Turnigy 2628/10 1400Kvm motor is a bit under speed for this modification, but for now, its what I've got.
Needs 2 or 3 more mm
Others were successfully using these props on their Wild Hawks so I did not think it would be a big deal and picked up a few of the size I mentioned above. I tried to install one of these 6" diameter props but, it hit the tail boom on my plane, so I needed an explanation of what I had done wrong and a solution.
After some correspondence with Fishbonez and NJSwede, they said it should have fit, but if it's only a few mm, I could just cut out the foam. So back to take a look at things.
After looking at my situation, I decided that I should be able to move the screw holes for my motor up enough to create the needed clearance. After unbolting the motor, this is the view I had showing the alignment marks I used to locate the original mounting holes.
New holes marked and drilled
Ready to mark the new holes
I added these lines to help layout the new holes directly above those that are already there. It looked like I should be able to safely move the holes straight up about 6mm. I marked them out and pilot drilled them with a 1/16" drill bit.
It fits!
Just enough clearance
Fitting on the motor shows that the clearance is just right. This is probably closer to the shaft location of the original motor than my original modified location. This would explain why this prop did not work before but does now.
Original motor location, face view
New location. You can see the old holes
I like this solution because it was a lot easier than another option I was considering (building a new firewall to add on on top of this one) and I did not have to remove any foam for clearance. Removing foam for clearance might have actually been the easiest solution, but I've had bad experiences with doing this before on another plane and so I really did not want to do this again.
Now I'm ready to test out those larger props and see if I get any more performance over the old 5x5 prop without burning up the motor or speed controller. I'll post again with the results.
UPDATE:
The 7" has much broader blades
I really like these APC electric props
I have since flown this configuration and found that this APC 6x5 prop, while much better than stock, was not performing as I had hoped. I have since taken a 7x5 and cut it down to 6" in diameter and carefully trimmed and re-balanced. As these APV props have a much broader blase mid section they grab much more air than others. Most other props have the same blade width for a series of props and the only thing that changes is the length.
I now have all the power that I need and am seeing the performance of this torqueie 1400KV outrunner. I have also tried this with an 8x4 and with similar results. See my Wild Hawk vs Wind post for how well this configuration did.

While I'm waiting for my battery parts to complete my home made LiPo battery and while I'm waiting for a calm day to fly, I've been playing with my new flight simulation setup.
I was originally going to purchase the E-sky 4 channel controller because it was so inexpensive (~$20) and I did not want to spend too much money to get started. While shopping for this I stumbled across a similar product from Dynam. This product comes with a 6 channel controller (usb connection to computer) and the same FSM software as E-sky. Not only did it come with more functions but is was cheaper too (~$14)! So for about $32 I purchased two from HobbyPartz.com (they had free shipping for orders over $25). I bought one for me and on for my Dad.
I was a little disappointed that it did not come with the software on CD but it is a free and relatively small download from their site on the Internet. The instruction are relatively simple as well and within minutes I had this up and running on my laptop computer. What a Blast!
The scenery isn't the greatest, but it's adequate, and more importantly the flying seems realistic. It is a little kludgey in that planes without landing gear must be hand launched and will slowly sink their tails into the ground and the trees look like two sheets of cardboard joined together and stood up in an x shape. But for this price, who cares.
From some searching around I found out that this is an open source project started by a couple of guys in Europe and that it is compatible with scenery and planes from other programs. I will see what I can do to add some of those to my installation.
For now it does have the Hawk Sky (made by Dynam and what the Wild Hawk was patterned after) and it seems good enough.
I'll have more soon.
