Death fighter Posted July 13, 2016 Posted July 13, 2016 Hi all, I brought a nuprol 999 version 3 gearbox which got deliverd today, I installed it but it seems the motor does a few spins that stops and move slightly on each squeeze of the trigger. I'm using a 7.4 v nimh and just wonderd if I should be running it on a bigger battery or should it still work with a 7.4v. Thanks
Death fighter Posted July 13, 2016 Author Posted July 13, 2016 Scratch that my battery is an 8.4 however I still have problems with the motor not cycling and its brand new!
Dechande Posted July 14, 2016 Posted July 14, 2016 Check the battery is fully charged, next check would be motor height. If the motor is set too high it will do what you're describing. Do you know what spring is in the gearbox?
Death fighter Posted July 14, 2016 Author Posted July 14, 2016 Sorted it, seemed my battery was knackered! ??
