i have the integy 55t which im gonna be upgrading this weekend. CC sidewinder and yes it rolls down facing forward also. any suggestion on what motor to upgrade to? i dont have the same pop in my throttle that i had before i switched to lipo battery.

you dont need a new motor, you need drag brake!!!

99% sure you can castle link your sidewinder and program it.

The sidewinder doesn't have a great drag brake but check the settings with a link. Getting a puller will help too.

i'v only been crawling for about two months now so im not sure what a puller is. can u explain what a puller is or send me a link to where i can find a puller?

thanks

you need to figure out what your drag brake is set to before you spend any money. It won't matter what motor you buy if your drag brake is set to 0.

i know my motor has nothing to do with my drag brake but i was looking to upgrade motor either way cause i dont get the same pop when trigger is pulled then released quickly. before i could pull and release trigger really fast and my rig would jump as if it was bout to take off, now if i do that nothing happens, i actually have to pull and hold trigger for it to take off.

i figured that this problem was a motor problem. what your opinion on that? also what motor would u suggest? still new to crawling so not sure what to look for..

sounds like you need to program the thottle curve on the ESC too.

again, 99% sure you can adjust that via castle link.


or, get a bigger pinion for more wheel speed?

When you switch back to the other battery is it good?

What batterys did you have, what do you have now?

i used to have a split Nimh batt, 1500mah. now i have a 3s lipo, 1500mah 11.1v

i havnt tryed to switch back to the split pack just cause its a lot harder to mount on the battery tray that i have now..

Wrong. The Sidewinder has a completely programmable drag brake.

Lildjloop, hook up the Castle Link to your Sidewinder and you can set the drag brake on the "Basic" tab. Those Integy 55 motors have fairly weak magnets (compared to a motor like the Cobalt) and have difficulty holding the vehicle on steep inclines/declines. If it were me, I'd set the drag brake at 100% then test it out.

When I switched from a regular brushed motor to a Cobalt motor, I had to turn down my drag brake to about 60%...and it still jerks to a stop!

I'd check your lipo, sounds like it has a bad cell. You should have picked up some punch.

How long have you been running this motor? The brushes might need replacing.

As for a new motor.....you cant go wrong with the Holmes Hobbies 7T Cobalt Puller in a 2.2 crawler!!

this lipo is only a week old. i havnt even had a chance to do actual crawling on rocks just running it on the grond.. not saying that it doesnt have a bad cell bad god a sure hope not..

measure how many volts it is putting out.

i'v been running this motor about 2 months maybe if that. i'v only dont actual rock crawling with this motor maybe like 7 to 10 time at the most. it should be fairly new but im not sure how long these things are suppost to last either.

if i was to upgrade motor would it be better if i went with a brushless motor? would i have to change any settings on my ESC if i did go brushless?

also where can i pick one of these Cobalt motors? Does RC Hobby carry them?

Nope....the only places (that I know of) that sell those Cobalt motors are Astro Flight and Holmes Hobbies.

Yes, if you add a brushless motor, you need to change the setting on your ESC to "brushless". However, those brushless motors will have WAY less drag than a brushed motor. The brushes are a major component in creating drag in the motor.
