iflyatcae, the gearbox that is part of the GWS EPS-400C system. If you go to the Balsa Products web page I provided the link for, they show the motor in the gearbox and provide an order area for the gear box parts. I use the 3:1 ratio.
Captain, I am not sure about my motor. That's why I made the hatch!
I don't know if it's going to supply enough thrust with 11.1v Li-Po setup. It felt good, but, I can't tell with out flying or having a thrust measure instrument. I presume a set of scales that will weigh the amount needed and be able to zero it out with the plane suspended from it. Put power on the plane, pointed downward, and it should show the thrust. I guess getting the scales is the problem!
