let me first say hi this is my first post on this site .... OK so i have recently got into the wonderful world of rc bashing just so much fun and have found many hidden tracks around my area . i started out with a 16th scale e revo love this little guy . soon after getting that little guy my girlfriend showed interest in going out bashing with me (win win i get a hot chick to look at and a bashing buddy) so i found a 2002 traxxas stampede that i bought for her i replaced all the electrics all metal internal steering servo esc (xp digital sc500bl) with a reedy 3300kv and run 7.4 lipo 2s i figured it would be a good tough truck and that it has been we have both been out many times and im always the one that has to take some time to fix my car while she is still jumping stuff but the last couple of time going out her truck would not take off smoothly it reminds me of a real car out of time ..... anyways it stutters then goes fine and i did some research and found out that maybe some dirt or small rocks got into the motor so i took apart and cleaned it out but that just seemed to make it worse with the motor out of the truck its shaking violently before starting to spin with it in the truck it only shakes horribly did i under size the motor i dont know the gearing (tooth count on pinion or spur) at all i used some gears that i got when i bought the truck from any craigslist any help would be much appreciated and thank you for any help you can offer

You might want to try switching the electronics from your MERV into the Stampeed to try and figure out the exact cause. You can buy used electronics fairly cheap on Ebay.

I hooked the motor to my e revo and it still did the same thing do you think I need to just buy a new motor if so what would be my best option not looking for stupid fast speeds but some tough as this is my girls car and she's still learning

Not sure, but if its a b/l motor, something might be shot in it, especially since you pulled it out of your g/f's car and its doing the same thing in your car. How many turns is it?
Try getting a larger turns motor for her. That'll slow her down til she gets the feel for driving it!
Keep us informed!

Rooster696

how do i tell how many turns it is the only thing on the motor is reedy 3300 kv

also what would be a strong but cheaper motor that would work well in her truck

I like the Tacon 3650-2950KV motors for cheap sensor-less.

Used Castle Creations ive bought a few on eBay with no problems. I don't remember the kv rating. Something like 3500 or 3800. I run a 1/8 buggy now so I don't recall. Perfect for bashing.

Sounds like the motor may be "cogging" this is pretty common with non sensored brushless motors. If you took it apart you may have not got it back together in the same location or position. Plus those 3300kv motors are an rtr motor, and are known to be unpredictable...as far as quality. If you can turn the end bell on the motor this may help a little.

If you don't know about HobbyKing.com you may want to check them out, lots of great parts at great prices.

Rooster696

I have a Hobbywing WP SC8 120a that works great. Should run that 3300kv with ease. Search around, I got mine for about $65 including the program card. Good luck!
