I use the customized Neugart gearbox and 65120 motor, to build a more efficient propulsion. Neugart PLPE 50 's radial force can reach to 800N. Once I receive the gearbox and will test the propulsion with different kv to find out the best combination.
My original plan was to put the ESC inside the hull(innner diameter 68mm)，but this version is too big(diameter 90mm).
I’ll use this version with external mount and will redesign other version which can be placed inside the hull.
I will use 56114 motor, and want to reach max power of 3500w and with max rpm of 12000(max rpm of gearbox is 3000).
