Diggity,
1. Will you release the parts individually? I would consider a conversion kit, at most, if I had to. But I don't have a need to buy the whole kit.
2. It's hard to tell from your pictures, but does the transponder mount like this?:
3. You said you adjusted the servos to allow for the turnbuckles to have proper angle. Then I'm assuming you drilled servos holes? If so, what servo did you use for those holes?
4. It sounds like, with the 3D12, you can adjust the battery position from side to side a little bit to help with weight distribution. That's a great idea. How small of adjustments are we talking about?
