I am putting my A-10 together now in hopes of flying tomorrow. What a great looking plane! I really would like to know what the C.G. should be so I can have a successful 1st flight. No mention is made of C.G. or suggested control throws in the instructions.
PS The sound the fans make is awesome! I want to find some r/c tanks to blow up!

It should be 2" back from leading edge.

I used the 30% rule and the CG came out to just that...2". Thanks!
On my second attempt I finally got it in the air, barely. About 15 feet off the ground and 25 yards out I began to lose radio signal. I managed to get the plane heading toward me and signal returned but crashed in the grass. The next flight was more of the same. No Fun.
This is a great looking airplane, but as far as being something to fly it is JUNK. I guess I got what I paid for, but on the other hand, I have seen stuff from WalleyWorld that would at least fly.
Good luck to NitroModels...may they never run out of suckers!

Did you range check it first?

Yes I did. With the antenna down I walked away from the plane about 15 yards and the plane stopped responding. I pulled the antenna out a bit and walked about 10 more yards until it quit again. I pulled the antenna some more and it worked. Seemed ok to fly because I did not think my flight would exceed 50 or 60 yards anyway. This was without the fans running.

Sounds like it failed the range check... which in turn caused the problem you had with it failing.

You should be able to get out a good 90 paces with the antenna out only ONE segment... or at LEAST 50 paces with a single conversion RX.

Assuming the supplied TX or RX was bad...

How did the plane look otherwise? Did it look OK?

From the sound of it, it took off fine but died in the air. Did it seem to have enough power to take off with no difficulties?

Let me answer your questions like this. Our paved airstrip allows almost instant altitude on 3 sides. That is the only reason it got airborn. Once in the air it was a struggle to keep airspeed up. All I could do was try to stay level and moving forward to keep from stalling. I managed to get the nose around to come back toward me when the fans started cutting off and on making for more work. As it got closer the fans picked back up about the time I am trying to land in one piece. 2nd flight was the same story. Both landings bent the gear and the last one cracked the fuselage behind the wing. The 2nd flight was with a "known good" battery out of another plane. 8 fresh "Robert Conrads" in the TX.

I fixed the damage and tried again yesterday. I moved the antenna outside of the plane.
Same results.

I don't think that the problem is due to the antenna placement...

It sounds like the RX is not working properly ( or could it be the TX? ).

You bought the RTF right?

The fans shouldn't have cut out, as the ESC is barely taxed with the included batteries, which makes the RX the most likely culprit.

I assume that when you static tested it on the ground the fans ran up fine and produced a decent amount of thrust right?

I usually guage how my planes will fare by holding them vertical and running them up to full power. The thrust should pull ( or push ) the weight of the plane straight up minus the weight of my hand, with no problems.

Everything works until about 25 yards out on range check. When I get it in the air and make my turn is when things get bad. When I get it back close it quits acting crazy.
The fans are pushing. But it is barely enough to push it in the air. No speed = no control surface authority. Right on the verge of stall.

Did you purchase the RTF?

If the RX is bad you may not be getting full throttle range.

Yep, RTF.

I'd classify this as: "You received a bad radio setup."

See if they'll exchange it for you.

PM John here too.

I purchased the same model, and I encountered identical problems both times I test-flied mine. I was doing it with a friend at the time who was already fairly experienced with RC aircraft, and he deduced that the airplane is simply not getting enough power with the stock components.

I also read posts from several reviewers on this forum:

http://www.rcuniverse.com/forum/m_7077307/mpage_1/key_/tm.htm

These guys tell you everything you need to know about this airplane, and the bottom line is it will require numerous upgrades for it to fly well. I was told by one member, Rysium, that the first thing to upgrade was the radio transmitter. You are using the Guanli Skysport the plane came with, I assume?

I plan on buying a Futaba 72mHz radio, and a more powerful and stable battery (the stock one the plane comes with only lasts about 2 minutes before it dies). I also plan on buying brushless motors as well.

You get what you pay for, which is why the A10 they give you isn't all that great a flyer when you first get it. But there is a bright side: you get a lot of experience with the workings of an RC airplane by having to tweak it so much and make so many modifications. Rysium made a bunch of upgrades to his A-10, and this is the result of his efforts:

This was a hundred bucks I spent for something different to play with. I have a Hobby-Lobby Decathalon that is fun to fly. I guess I will stick with I/C engines and balsa. The A-10 looks good hanging in my shop where it will remain.
