Hello, I took my s50 out of a 3 year hibernation and after cleaning the engine the beast started with not much effort which surprised me a lot. However, after factory resetting the needles I took it out for some tuning and two main problems came up
1) The servos seem to be acting on their own when there is some range between the transmitter and the receiver. I mean seriously moving on their own both the throttle and steering servo. This happens with the engine both on and off. If the transmitter is a couple of meters or closer to the truck then the servos don't move on their own but there is still some buzzing noise coming out of them. Any thoughts on this? Is it the receiver that needs replacing?
2)Sometimes I apply throttle, I can hear the engine revving up but the truck does not move, then all of a sudden it might start to move. Is this some kind of gearing problem?
Thank you in advance, I would really like to get back into this hobby.
