gearing question
 

i'm using a novak 55 turn in my ax-10. i started out with a 14 tooth pinion then changed out to 20 tooth. what are some disadvantages of doing so if any at all. to be honest i'm enjoying the bump up in wheel from doing so but really liked the torque i was getting from using the 14 tooth.

You answered your own question. With the 14t you get more torque but, sacrifice wheel speed. And with the 20t you gain wheel speed but, loose some torque. You could try a couple in between and find a balance you like.

You will see decreased run time with your battery too. If you like that wheel speed, start looking at bigger batteries (more voltage) with your original set up... or the same voltage but a numerically lower turn motor. 35T or 45T motors are usually a pretty good middle ground.

Get a handwound motor and you get the wheel speed but won't lose any torque.

you must have been reading my mind about batteries. right now i'm running apogee magnum 1000mah 2s lipos. i'm definitely thinking 1500 2s lipos in the future. my running time is really cut down because of the rooster crawler esc. man that drag brake can drain the snot out of a battery.

Really? What kind of runs are you getting with the Rooster crawler and the 55 motor? I have a friend looking to get a Rooster Crawler and the 55 combo. He was hoping for a 20 min run time on a 1500 pack. I'm just wondering if he's going to achieve that or not.

i'm guessing 20 mins is very acheiveable with a 1500 mah 2s lipo. with my 2 1000mah 2s lipos i'm getting right at 15 mins tops. i just remembered also that a rooster crawler esc will not hold 3s lipo power so now i'm really thinking 2200 mah 2s lipos from zippy packs. but in my opinion you need more than 1000 mah if your running the novak setup.

Thanks for the info! When he asked me what kind of run times he could get, I told him probably 15 to 20 mins tops. I guess I wasn't to far off. That sounds pretty reasonable to me.
