RE: Training gear for MX400...
Just an update: The set arrived today along with my aluminum mount for the gyro reposition, and it is indeed too large. It was very tough to judge the size on Tower's website since no dimensions were given. When I called about the return I mentioned they should include the dimensions in the description since it is difficult to tell from the pictures and description if it will work. I will most likely return this set and fabricate my own, or find a smaller set like the one posted above. It probably would work well for a .30 size heli but not the MX!
