RE: T-6A Texan II 75-91 ARF build suggestions
A123s can put out a lot of current without dropping voltage too much. I and lots of other guys use just two of them to power 40% IMAC planes with no problems, and they can draw a lot of juice. If your set-up is dropping the voltage significantly just by pulling up the retracts I would definitely sort this out before the maiden flight. Have you used an
inline amp meter like the H-9 to see how much current is being drawn by the retracts?
I did read that the steering was a weak point on those retracts.
