Hey I ran about 2 tanks through my Sportmaxx, then it started cutting out and dying every once & a while. I let it do this twice, then I took it inside. I cleaned the air filter, and put it away for the night. The next day I come home from school and take it out, put the servo battery in, and test the servo. The wheels turn & everything but the throttle wont open or close using the controller. I changed batteries in the controller twice. Then I switched the plugins for the steering & throttle servos (so that the wheel controls the throttle and the trigger controls the steering) i thought this would tell me if it was the throttle servo or the reciever. The throttle still didnt move. I think I have a bad throttle/brake servo.
Can anybody confirm for me?
And if so, does Mitchell's RC carry replacements for my servo?

i have seen this many times. and it will take removing the carb and smoothing out the bore of the carb. you also have to make sure that the ball on the carb is facing just the right angle so it pulls the carb open smoothly. light (600) grit sandpaper will do the trick. good luck. Ron M.

Pappa Ron is more than likly right he knows way more than I do... but to take your testing one step further before going in to sand things... when you tested your servo in your sterring slot was the throttle servo hooked to the carb. Try hooking your servos in the right slots and disconnecting the throttle linkage from the carb.... If the sevo moves do what Pappa Ron mentioned... If the throttle servo does not move..... try switching the servo wires around to have the trottle in the sterring slot and try again... if the throttle servo works then I would say bad RX.... If it dont I would say bad Servo. Also double check with the sterring servo that it works in the throttle slot. That should confirm that the RX is good and the throttle servo is bad. If all else fails Bring it in to the shop and have them look at it. Im sure that they will be willing to get ya set up right.
Thats my .02 I hope that is the simple fix that Pappa Ron said.
Please correct me if my train of thought is off base... it wont be the first time and im sure it wont be the last.
Good Luck and let us know your findings...

I tried, the steering will work in the throttle slot and the steering slot, but the throttle wont work anywhere or anytime. Im almost positive its the servo.. Im gonna bring it up and have it looked at later i think..
thanks for all the help!

Well, turns out it wasnt the servo, it was the failsafe..what a joke.. said battery was too low although i charged it all night.
Anyways got home ran about half a tank, stripped the flywheel (brake got stuck one somehow) all in good fun

well i'm glad that you figured it out without too much trouble. but it is always speculation when doing a repair without seeing it in person. but the price was right....right? have fun and i'll see ya around.

Yeah ive been considering a Revo, but im not sure that its right for what i wanna do... not looking to race (at least yet), more into just backyard bashing, very interested in both... not quite sure which yet
As for now, i must get out the shed and change my Front left bulkhead...broke that too
GOOD OLD ALUMINUM REPLACEMENTS!
thank the R/C god for aluminum
having soo much fun with this hobby.. its even fun switching out parts

matt working on the cars IS the fun part of the hobby. or building the cars.

yes! it certainly is. Today i setup a jump in my backyard.. got pretty comfortable going off of it, tried a backflip **CLOSES EYES** and sorta landed it... landed on the back a little hard and broke a lower a-arm this time...
if its not the upper its the lower.
Ive been looking around at Revos..might have to go with an LST for my crazy driving.
ive stopped hitting stuff at least
