The Flite Test A-10 Warthog is one of the largest and most complete Flite Test kits available. This kit includes all of the lasers cut components, including the firewalls, hardware, pushrods, duct formers, landing gear, and wheels. With a wingspan of over 60 inches, this plane really carries itself well through the sky!
Although this aircraft is big, it is not a complicated build. It is cut out of eleven sheets of foam that fold and bend to creating an extremely rewarding build process. Producing this kit is a labor of love with almost an hour and a half of laser cutting time.
This aircraft has great flight characteristics in the wind and calm weather alike. When you put a 4 cell battery on this aircraft it is fully aerobatic and you get the perfect pairing of speed and efficiency. The flight characteristics of this A-10 are like none other on the market at this size. It performs like a real A-10 with vertical lines and incredible performance at both high and low speeds, and with the included landing gear set, you can easily land and take off of short grass.
The FT Warthog is a direct result of the Giant A-10 vs Tank episode! With such an incredible response to that project and particularly the aircraft build, Flite Test wanted to make it accessible while still maintaining a substantial size and presence in the air. Although this is a smaller version of the giant A-10 featured in the video, it is definitely an advanced build, but once it is completed you will find that it has some trainer like tendencies.

I fly from a desert area (no grass, just hard pack sand) so I added a skid made of foamboard to the tail. Its covered with packing tape and keeps the vertical fins from dragging during landing. I plan to try to replace the 30A ESCs with something larger so that I can use a 4S battery. I am concerned that the ESCs are buried in the wing with little airflow and that even larger ESCs may be prone to over-heating.
Since my original review I added 40A ESCs and have experienced no lagging of the motors when flying with a 4S lipo (~6 minutes with a 3000 mAh battery). The batteries have been warm after six minutes of moderate flying, so I suspect that the ESCs are as well. Today I suffered loss of control which caused my A-10 to crash with significant damage to the fuselage (probably not repairable). Upon inspection it appeared that the elevator control horn pulled out of the elevator causing loss of control. Although I followed the video instructions for gluing the horn and added extra hot glue around it, it pull partly out of the foam board. Anyone building this kit may want to use a more secure type of horn to accommodate the increased forces on this large model.
1. Two of the 11 foam laser cut sheets were burned and cut all the way through. Lots of tape was needed to remedy the parts that had holes. Minus one star for poor quality control.
2. The kit did not take into account that the non-Flite test motors are reversed and then mounted, leaving the back end propeller shaft jabbing into the wheels. My own improvements helped remedy the problem, as opposed to damaging the motors and the wheels. Minus 1 star for the kit being prematurely released without the correct power pack being sold. If you can remove the keyed shaft at the “back” end of the motors, please disregard this comment.
Other than that, the kit is worth nearly every dollar. If you want to purchase this kit and use full rudder controls and not the standard differential thrust, purchase some y-leads (one or two) for connecting the motors and the ailerons in parallel instead of programming each motor individually. Don’t be afraid to improvise on these foam craft. Happy flying.
You do need to plan ahead. I wished I had devised a landing gear setup to connect into the nacelles before I built them but I have a few ideas. There are supplied reinforcements for the nose gear, and it is off-set just like on the actual plane.
I had no issues with the quality of my kit. Only on the rudders did I notice a slight burn through where you dig out the foam, but they were only pin holes.
Follow Josh's build video and you should have no problems. A few spots I had to watch the video several times to make sure what I was doing. Test fit your parts often BEFORE glueing.
Only problem I had is the tail cone, it has many irregular shapes/facets and requires many bevel cuts. I found it easier to get it lined up flush with the tail of the plane, and then glue it together as I attached to the rear.
Plan on doing mine up in some sort of camo design, have not chosen colors yet, but figure light gray for the bottom, possible light gray/brown/green for the top?
Since I had a spare XR8 (frsky) receiver laying around, figured I may rig up flaperons even though it does not need flaps.
If I could change anything, it would be to include or offer a landing gear kit. I may install a steerable nose gear in mine.
Should also include a fake gun barrel. What is an A-10 without the gun.
This is a BIG plane, and I am impressed
I got hold of some Eflite retracts and installed them. Looks much better and they retract forward. I went to 3 blade 9" props to get me a bit more ground clearance. Just wish I had built in the retracts before I built the plane. Hope to maiden this week end if the weather cooperates. Check out the Flitetest Facebook page, several of us building this beast on there. Many pictures and ideas being shared.
I used flaperons for the landing and it just makes the approach so much slower and smoother. I started this project in January and had to wait 5months for the plywood flite test sent to arrive (borders shut covid-19) but in the end I completed it.
Running off a 4s 2200mah battery this just flies so easy with a 4min 30s flight time and can do whatever you want it too. 10/10 would recommend if you are a intermediate pilot for a great model to build and fly.
After several great flights, I broke-out one motor on landing. Repaired and flew a few more good flights. This week I landed and broke- out both motors. I either needed to add landing gear, move the motors higher, or go to EDF's. I have two 12 blade 64mm EDF's I salvaged from a Freewing A-10, so I mounted those in the existing rear nacelles using the existing 2700(4S) battery. I moved the battery forward to move the C/G forward. I hand launched the A-10, it bounced off the grass and was airborne. The plane flew good, but was way under-powered. Replaced the 64 EDF's with two Freewing 12 blade 70mm EDF's and changed to an 1800(6S) battery. Two attempts to launch went into the grass(Too Heavy). I think the 70 EDF's would have worked, but I would need some kind of high-start launcher to get the plane up to flying speed. My advice is stick to the original prop set-up and be careful how you land.
While the build video is fairly straight forward, you'll find that it lacks any details for the nose landing gear, and doesn't have any options for a 'wheels down' configuration for the rear gear. You'll have to figure that out yourself. Furthermore once you are done building you will find extra plywood pieces left over that aren't mentioned in the video at all. What are they for? Why are they included??
Once the build is complete, you'll quickly find on your maiden flight (as I did) that on 3S batteries the power pack C can barely keep this plane in the air. The entire flight I had to keep my throttle pegged at 100% and I didn't dare trying a roll. I bought this kit because they show it doing rolls, loops, etc. I figured ok, they mention it flies better on 4S so let me give it a shot...
Unfortunately this is where the Power Pack C falls flat on it's face. The motor is only rated for 2-3S voltage. Running it on 4S pulls ~480 watts per motor when it is only rated for ~250 watt bursts!! The motors get hot quickly, even when using only 50% throttle.
The build video shows them using Flite Test Radial motors. Reading the specs for them is incredibly frustrating! They vaguely state: "Incredible Thrust Output (Over 1Kg/motor on 4s and most prop choices)". How many amps is that? How many watts? What prop sizes are recommend? So many questions and so few answers.
I've resorted to swapping to RC Timer 3530/10 motors with 40A ESC's purchased elsewhere. That required redesigning the nacelles to fit the bigger motors, which I didn't expect to have to do when I bought the full kit AND the recommended power pack! I have yet to remaiden, but I've now got over $250 spent on this plane. For that kind of money the Dynam A-10 or the Freewing 64mm A-10 can be bought and flown right away with none of the above hassle.
Stay away until they update the power packs, add landing gear instructions, and turn this into a more 'polished' product.
Overall I can only rate this kit as 2/5. One star for the physical design, and another for well cut parts.
I am waiting for you to make big airplanes
