throttle stays open
 

hey guys, my nitro buggy is playing up, if i turn my receiver on, everything is fine, if i turn the transmitter on the throttle servo opens the carby up full and i get not response if i try to apply the brake, the steering funtions properly

Have you tried reversing the servo?

no i will tho, i have young kids, um with no singnal it kinda shudders a bit, i did get it working, by playing with some of the trim dials but when i started the car it opened up and took off, i caught it tho

ok so i tried reversing it, it seemed to work, so changed it forward and it followed orders, but it flicked open again on startup, reversed it again and started it, got the same thing, its weird it kinda shudders with transmitter off, my last run it was working perfectly

Zero out your trim. Set your epa to 100. Try another servo.

What radio are you using?

Cougar, 2.4 gig, yeah i tried to play with the trim but when it fully open it wont move even with the trim
I will try to get the model of the radio in a minute, its the ine that comes standard with a thunder tiger eb4 s3

could have got water in it?
I washed my buggy before and got some in it and it acted like that. I took the bottom cover off and it has some moisture in it. so blew it out with compressed air and it works fine now. I sealed it up with some sealant this time. and around the wires.

i generally clean it with baby wipes, but maybe, i do keep it outside but it's not been cold, quite the opposite, which cover are we talking about? the servo?

yes the bottom cover on the servo where the electronics of it are. mine was wet.
