Status: offline 		ok so im a lil lost. I have a ofna hyper 10tt with castle sct esc, 1410-3800kv motor set up and can only run 2 cells with out burning up the esc. Was looking at the mamba max pro esc with 1415-2400kv motor that is safe to use 3-4 cell in this buggy. Making this swap should have this rhing running way faster due to the extra voltage,right? I feel that this is a stupid question but i would hate to put it in an find that it isnt much dif.  Thanks for any help

Try increasing the pinion by 1-2 teeth and see how you like it. but keep an eye on ESC/motor temps, as long as it stays below 170-180 degrees you will be fine. How fast do you want it to be? you should be able to get 40 MPH out of that combo with out many heat issues on 2s.

But to answer your question, yes more cells will make it faster. 3800KV means 3800rpm per volt. on a fully charges 2s lipo that is equal to 31920rpm. If you just upgrade to the mambam amx pro ESC you can run 3s with this motor which owuld give you a max rpm of 47880. A 2400kv motor on 3s is equal to 30240rpm. So everything else being equal this combo would actually be slightly slower than what you have now. But it will have more torque but top end will be slightly lower. You could go 4s with that combo and have 40320 rpm which would be faster and have more torque. but when you start putting in larger, heavier batteries along with more torque you may see a decrease in the handling/agility of the truck along with oncreased wear on the drivetrain. its all a balancing act of right rght amount of power toque, speed and weight to get the poerformance you want out of it.

Status: offline 		That actually answered my quesion perfectly yakfish. Im obviously new to this and not to clear on exactly whats what yet.  An i guess over kill was the goal savage. I also have a 1/16 e-revo and love its over kill power. The set up on the hyper 10tt is actually prob right on with were it should be as a all around balanced track car.  Im just not at the track that often an end up playing around on the road.  I think im just going to leave the motor and esc on an just tweak the gearing an get all I can out of whats there.

I would start with increasing gearing as well. But just keep an eye on the temps and don't let it get too hot.

Status: offline 		Just get yourself a little infra-red thermometer so you can monitor your motor and ESC temps while running.  Normal BL motor operating temp is around 150-160F.  Pushing too close to 190 can cause damage to the motor. (Basically, the magnets come unglued)  Rule of thumb: If motor is too hot, gear down. If ESC is too hot, gear up.
