Ok i just got a losi 8ight t RTR and im on my 9th tank of fuel now 3 out of 10 times when i get off the gas my servo dos not respond as good it stays on the gas for about a second is that right or is the servo going bad or the radio having issues or something else thanks

servo is going bad .... all RTRs will need to have upgraded servos, they dont seem to hold up... id replace before running it again, it could stay at WOT and then you could lose your engine and possible break a bunch of stuff on the truggy.

Ok thanks

try charging your batteries first. thats what happens everytime mine start to die.

Plus 1. It could be just a low rec. battery.

I have the same problem. I am using the crap losi servo. I have my rx pack fully charged and it still seems to stick for a quick sec. It sucks because sometimes it sticks just enough to the point were you land wrong :/ oh well, need a better servo.

Yep that is the problem. It is the servo. I upgraded to the Hitec HS5965MG and it works great. No more throttle sticking issues.
