Hey guys...im totally new on EP flying. I bought E-Flite`s Ultimate 3D also, and have a Ripmax XTRA2829/16 Brushless outrunner motor
Dimensions: 28.8x29mm
NiCad/Ni-MH: 6-10 cells
LiPo: 2-3 cells
Operating: 4-9A
Turns: 16
RPM per Volt: 760
Weight: 57g
Current at Max Effic: 10A/60s
Shaft dia: 3.17mm

could I install it somehow to this aircraft? can and should it go with the included 6:61:1 gearbox or should it go direct?

Thanks!

Sanyul.
