Almost done with the assembly of the aeroplane, but I have problem to synchronize the two motor (TowerPro BM2410-9T). I reset the Ecs but the one motors runs faster (both motors & Ecs are brand new).
They start together but in half throttle you can understand the difference.

and be sure to do them one at a time (disconnect one ESC, do the throttle calibration on the remaining ESC, then repeat for the second ESC).

Good luck,
Jeff

First I reseted both Ecs and then calibrated each one. Then i made the mix throttle to Aux1 100%. The right motor starts first and the left motor second,
I synchronize them with the offset Dx7 menu option and the two motors start together (maybe this is my mistake ).

Yeap with offset 0 the right motor starts first (connected to throttle) the left starts second connected to Aux1), now it is better. Tomorrow I will borrow a blade tachometer from my friend to be sure that I have almost the same rpm in both motors.
Also I will try with Y connection to see the difference.

I tested my twins with the L3010C. It has tons of power and flies fast. I've also tested it with a few pounds of candy on board. It flies a little sluggish loaded but it handles the load fine.

The Twins Cargo plane Turnigy L3010C (4 min 55 sec)


the little mishap at the end was me losing a prop. I guess lock nuts would be a good idea. the plane survived just fine.

I've got an armin wing with carbon fiber spar, zip tied to two carbon fiber rods attached to 1/4" ply gorilla glued to the fuse. I pulled some serous G's with it today, but wouldn't try that with a payload.

I finally found this thread and how to do twin motors. Happy days. So all I have to do to run twin motor setup is to disconnect the red wire on one of the esc's. Is that right?

Tom

Forgot to ask about the batteries. Do I use two smaller batteries instead of a larger one? Hooked to the two esc's.
