Motor responds and runs full throttle only
« on: August 18, 2019, 04:51:25 PM »

this is on a viper bait boat,


But Iíd imagine itís a general rc problem. Iíve been fixing mine and my friends boats for a while but Iím stumped.


If I turn in the hand set and then the boat, the left motor runs forward if I push forward on the hand set, if I pull the stick back motor runs backwards but wonít stop in the middle, other motor is fine. Everything else works perfect,


Iíd thought speed controller but I can't find any, there is a control PCB and thatís it,


Iím thinking itís the pcb but donít really know how to diagnose the fault.


Thanks in advance.


I have a spair handset and rec, but them on and it would not control anything,

Sounds to me that the circuit board has gone dullaly....no cure for it bin it and either put a new one in Or get rid of all the wiring and start again with proper rc gear....done quite a few of the vipers.

What i thought, for a quick fix, could I buy 2 speed controllers and wire then to the motors and in the receiver to by pass that part of of the pcb?  Itís tank type steering so am I right in thinking I wouldnít need a mixer?
