Unofficial "NQD" Tear into Jetboat Thread
75 pages of jetdrive stuff, so i decided to start this for the guys modding the "nqd tear into" boats
My Setup :
Tear into boat
3500kv 400 size outrunner
3s 2200mah lipo
Hyperion Titan 30a esc
GWS micro 6ch receiver
Digital micro servo for steering.
Custom brass coupler
Modded jet pump : have sleeved the bearing surface where the shaft runs through the jet unit with 1/8 k&s brass tube, sharpened the stator fins.
First run stock was quite pathetic, stock electrics are junk.
2nd run with the above mods - quite quick until an un harmonious vibration arose. On further investigation it turned out to be the impellor sliding back on the shaft, so i drilled a 2.5mm hole and tapped a 3mm thread and put the 3mm set screw through onto a flat i filed on the shaft
3rd run - Just nuts, this wee thing does 45/50kmh now, excellent handling and acceleration.
All in all im well impressed.
Next mod will be to go to a lower KV motor and/or try the 3500kv Motor on 2s lipo.
