New to crawling. I am about to order the xr10 with the following specs.

Holmes esc http://holmeshobbies.com/product.php...4&cat=2&page=1

2x holmes 45t motors http://holmeshobbies.com/product.php...&cat=17&page=1

Hitec servo hs 7950 TH http://www.hitecrcd.com/products/ser...hs-7950th.html

Do I need to order pinions for the motors?

If so what are you guys running and what should I order.

Thanks

The kit comes with 14t pinions. I would start with these. I am running 35t Tekin motors and i will run 13t pinions when they come off back order. I will start with the 14's though if that's any help

I am running 45t's I dropped down to 13t pinions to get a little more torque. The 13t seems to be a better mix of torque and wheelspeed for me but to each his own.

From what I've seen, 13 tooth is as small as I'd want to run. I have the motors jammed as close as they'll go with 13's and it's perfect mesh. I'd think 12t would be a bit loose.

flapjack · 10-17-2010, 06:16 PM

im going to run 14f 13r personally...robinson racing pinions all the way...

miner mike · 10-17-2010, 06:18 PM

14t in front 13t rear 45t Novaks a bit of a over drive.

jpterbl1 · 10-17-2010, 06:22 PM

I am running 45t's and started with the 14t stock pinions. I would start with the stock ones and change them if you feel you need more torque. Currently I am running 13t pinions and it is a good mix of speed and torque but not a huge difference in my opinion.

BFGcrawler418 · 10-17-2010, 06:41 PM

I am running a 10T in the rear and a 12T in the front (once it arrives) but I am also running 25T motors. I wanted to run 35T motors but I already had these so I thought I would gear it down and give it a whirl.

I am actually suprised because its not hard to control at all, should be even better once the 12T for the front arrives, Right now I am running the stock 14T in the front. I had to modify the motor mount holes in the plate in order to get the 10 tooth pinion to have proper gear mesh.

losichris · 10-18-2010, 12:53 AM

I was running 19f 16r with 45t handwound tekins, now im running 15f 13r with 35t tekins... The 35t motors work the best for me very smooth more touque and rpm's...

Menchifus · 10-18-2010, 03:01 AM

55T Novaks with 13 front 12 rear. Works for me. But I wouldn't know any better cuz that's what I started with.

Robbs2001tj · 10-18-2010, 08:29 AM

I am running 45t front and rear with a 16t up front and 14t in rear. Has a good overdrive in front. I will be going to 35t once these motors die and a 15t up front and a 14t in the rear

BEELZEBOB · 10-18-2010, 01:13 PM

I will be running 35t w/ 14t front, and 13t rear.

i just havent put the 13t on the butt yet.

darkmanx · 10-25-2010, 04:16 PM

What pitch should i go with?

BEELZEBOB · 10-25-2010, 04:25 PM

48 pitch

darkmanx · 10-25-2010, 04:45 PM

Thanks

Abavuso · 10-25-2010, 05:14 PM

Since this is my first MOA perhaps some one could school me. Why run 2 diferent size pinions?

If you are running a single ESC it will help out with clod stall

Flyin Hawaiian · 10-25-2010, 06:55 PM

It will overdrive the front wheels to help pull on climbs

Abavuso · 10-25-2010, 07:00 PM

Got it
