Thanks for the comments,
The dx6i lost two planes, first a Yak 54 on its 3rd flight, I was coming into a low fast pass when it just roled over and dug its nose into the ground! I had no input that would cause that, my thumbs were only putting in small movements, nothing to cause a crash like that!

The other crash was a Piper Cub. This was not me flying it but a man that has been flying for more than 30 years! my Dad got it on tape, you can see it just floting into a tree, he had no control what so ever, I might able to stick it on youtube if it would help?(you don't see it crash because my dad looks away at the last second but you see it going toward the tree)

We orderd a dx8 to see if that would fix the problem, We went to the flying field and got the Piper cub in the air, after taking of I found it was realy out of trim! It was rolling right so much that with full left input it was still slowly rolling right, I flicked into higher rates on eleavator so that I would have more pitch (I could hardly rotate) and aliron so that I had some roll, after about 3/4 of a lap I let all the sticks go to see how much more trim I needed after full left trim and lots of left rudder trim! At the moment my fingures got back on the sticks the cub started to spiral downwards(the same thing that happend to the Skyraider) but I did not have as much hight as I did with the Skyraider and the cub spiraled into the ground) After walking 300m we found the OS four stroke under the ground up to the fire wall! The cub had come down so hard that the os 56a was broken and would cost $100 to fix! Are cubs known to tip stall, or does this sound like a brown out?

We changed to the DX8 incase it was my DX6i impaticular, alone.

The Skyraiders elavator was set to its instruction manual, and it said that these throws were for normal flight. but it did look like alot to me; if it would help I can post some pictures of how much throw it has?

Thanks,
Patrick
