1/12 John Deere 870G

[carp]

Reg i tested a bit more today it dragged itself across concrete no problem but on grass it just stalls the stick, according to my calculation the motor shouldnt run any faster than 4200 unloaded on a 4s lipo, maybe i will get a tach to check what speed mine is doing, 5900 its pretty quick! arent the pumps only rated for 5000rpm? hasnt stopped raining all day so havent be able to test outside, hopefully over the weekend i can give it a proper test drive.
