Ok let me rephrase it, it's not a very good gyro especially when you compare it to something like the GY240 which is another entry level gryo and is superb. The helimax gyro is ok but doesnt last long and when you end up replacing yours, and you probably will, you'll want to get a really nice one. People replace their helimax gyro another one of the same kind and suddenly they cant get that gyro to work and end up sending it in for another one from helimax and begin playing the "I hope this one is good" game which, as you know if you love flying, isn't fun. Just my opinion though. The tail on my heli drifts like anything and I can't seem to find the sweet spot on the gyro yet and I'll keep you posted on that one too.
Yeah, having to split the frame for my first repair on this heli is pretty much sucky but gotta get-er-done... I plan on only loosening up the screws required to get to the part and replace it so if I can just bend it open a little and put another one in then I'll do that. I'm eying the new CNC parts coming out for the AXE 400 and I'm sure I'll quickly upgrade all of the parts available with the metal ones.
I'd be interested to know what battery you are using and what your flight times are on that battery. Are you using a different battery then the 2000mah lipo they recommend? I've heard amazing things about the 400 with the 2200mah Trex battery (
