Thanks marnochs for posting the pictures.

I am a little worried about your battery setup... By running 2 different capacity packs (I mean the 2 5S packs) you are going to have different RPM's on each motor if you run each pack separately to each motor. If you connect both 5S setups in parallel to both motors, you run the risk of the smaller pack over-discharging before the larger pack. Which is also bad. Either way, you are risking a single-engine out scenario.

Also, what ESC's are you using? I always recommend disabling the voltage cutoff on twin electric setups. I suggested this many times in the E-Flight P-38 build thread, and most people did not listen, had one motor cut out and destroyed the plane, and batteries. Fly with a timer. I have accidentally run my big lipos down 100% and they recharged with no problems. Now these are name-brand Lipos, like Thunder Power and Flightpower..Some other packs may puff a cell and be trash. But ask yourself this, which is cheaper (and easier) ...a new lipo or a new plane?
