I picked up a second hand ryft and have been slowly fixing the issues as i find them. First issue was holding throttle wide open truck would go for a few seconds then come to a stop, release the throttle for a few seconds and it will rip again. The fix was a different motor. Next issue is steering some times steering is great and at speed its hit and miss, i think its a servo saver issues and not wanting to return to center only in 1 direction while in motion. Maybe its a servo saver or maybe its a brown out issue. The last issue is a gearing problem that will be fixed when the junk dynimite fuse esc n motor are replaced, i have a copperhead esc waiting to go in just need to decide on what motor i wanna purchase and put in then I will address gear ratio and keeping the front end under it
