I recently bought and built my causin a 1:5 scale 23cc rc car and its running 2 jumbo servos .

My question is that i hooked up a receiver to it and the car constantly cuts out once you pull the breaks on in terms that the fail safe kicks in and i also lose the steering , the only way to get it going again is to turn off the receiver turn it on again and shes right again .

Im running 6V 2500mah pack but have noticed the receiver gets pretty warm .

Is it possible the load on the jumbo servo is killing the receiver or im assuming the receiver only sends a pulse to the servo so the amplifier and load would be carried into the servo .

Any ideas cause as ussual , i dont know why the **** i always get involved as every time i do , theres a genuin problem

Hmmmm,I've never used a hump pack,or large servo's but you would think that setup would work. Does the servo STALL at full brake? Thats the only thing I can think of.Dont supose the info with the servo's give a troube shooting guide huh.Or power recomendations?set up guide?

Have you swapped the servos around to eliminate the servo as being at fault?

You could also bypass the receiver and run direct power to the servo. I think the way to do it is just disconnect the red servo wire from the receiver and run it directly to the battery pack.

You sure the battery is charged? I know it sounds stupid, but voltage drop is one of the things the fail safe detects. It could also be a faulty fail safe.

yeah nuts , the batteries are on full and i also have a battery meter on it to see the drain under load and all good , yeah , swapped servos with no difference .

The thing you mentioned bout bypassing the power from the pack to the servos directly might be something i have to try , we do it on the helis to get direct power without losing resistance so might be something to consider , just never thought id have to as i have 3 x 1:5 scales with none of these issues .
