Perhaps there's some reason for this, some benefit to 3D?
No, zero positives to bad CG. It makes anything while pirouetting real tough compared to a heli with spot on CG. Piro comp takes over if level but piro loops and piro funnels are way tougher. I was having a hard time doing piro funnels on my 450 last year and then got to try a friends x3 with perfect CG and it turned out they were predictable.

I got both 150's bound to main TXand pitch setup perfect now, just need a gap in the weather to try them.

Hey, guys. So, I just bought a used one at a swap meet (yes, I understand the risks), and I'm finding that the tail-motor does not spin up with the main motor. I swapped the motor plug to the main motor port and confirmed that the tail-motor spins, so I know it is not the motor or wiring.

Has anyone experienced such a thing where this would be a programming issue on the board, or did I sadly purchase a board with a blown tail ESC in it? Is it possible to just get the ESC board?

- Jim

I had that happen to my new one after a crash and if I wiggled the board I could get it to work until I let go. Bad connection somewhere, but couldn't chase it down so I bought a new board. That sucked because I bought my 1st one used and the main motor wouldn't spool up. New board there also. It's a wonderful bird, but a week board.

I found someone kind enough to sell me a working board. In the meantime, I'll see if I can touch-up the posts and FETs and restore this one to life.

It appears the top board is the RX portion. I wonder what the pinout is to the flight unit? S-Bus or individual servo channels? I was afraid to try until now, but with my Orange R100 attached, I wonder if I can remove that top board and antenna in order to save a touch of weight?

yeah you could and it has been done...if memory serves the weight of the top board is around 0.2 gram so its negligible, at any rate these birds benefit from a bit of extra weight up front IMO due to the really bad CG...and some better protection for the really weak boards as the stock canopy offers very little
