yes, they come 18/87. I'd go down on the spur gear. 23/78 is what I run with a 13.5 (close to the 3300) temps are in the 140-150* range

Or could i just go up a few teeth on the pinion?

yes u could. but, not all pinions will fit with the 87 spur. not long before ur motor mt runs out of adjustment. u might be able to go up to a 21-22 before the pinion doesn't fit.

im running a 20/87 and ran a full pack on the track 5000mah 40c 2s and tmp was 138 and feels good for tq and speed but i think i need little more tq

ThunderbirdJunkie brainfarted on the spur size, sorry. It is, indeed, 87t. Get an 82t spur and a 24t pinion and you should be right in the ballpark and hanging with some guys making some big power.

What is the most powerfull brushless motor the tranny can handle, for racing and bashing?

just picked up a sc10 last week and got her on the track yesterday. broke the left A arm two times in a row what weight oil is everyone running up front and spring? its a indoor clay track.

I never broke a set of Arms, however some people just need that little bit extra, hope this helps.

You will also need the rc10gt hinge pins

im running 35 up front red springs and 30 in the rear with silver springs with the Scott Brown set-up from the AE web site and mine is dialed

I tried the stock kit (non FT) set up and it was complete crap with so much body roll the rear would step out constantly so I went another direction.

I'm running 40 up front with red springs and 35 in the rear with silver springs and stock pistons on a tight high grip clay track, stock shock limiters front and rear also. The front shocks are all the way in on the on the shock tower and inner holes on the arms.

I went to thicker oil to slow the weight transfer speed and body roll speed keeping the rear planed on a high speed sweeping corner. I also added 20% drag brake to speed the weight transfer back up for cornering grip when making a hard 180° u-turn. This had allowed the truck to rotate through the tight corner with the thicker shock oil.

I run m3 bow ties in the front on stock Associated foams with the corners trimmed off to make the tire crown more. The rear has goose bumps with a soft foam insert. I also run aluminum .5° rear hubs for forward bite.

Front ride height is slammed with the arms below level and the rear cvd's just below level. The truck does not bottom out as the thicker oil provides plenty of pack when landing the big jumps.

This set up has set the local track record and offers tremendous on-power corner traction in the sweepers to where I can drive inside almost everyone else no matter what truck they are driving. This set up is also very predictable on another high speed track that is much larger with big high speed jumps. I can't wait to try this set up outside to see what it will do.

I need to develop a setup for a large and loose track..I know i need to get tires, but have been running the stockers on this low grip track and it's been a handfull!!Can anybody suggest a proper setup for this type of track??Simple changes, like what would i need to do to get more rear end grip as the truck likes to squirrly dog it and gets loose easily when i am on throttle...It also likes to push through tight corners where i am coming through with higher speeds... Due to these high speed longer straight's b/f these tight corners I need to slow down significantly and turn without pushing to hard into the turn, than i get too loose when i give throttle to rotate and get out of the turn??Any basic setup recommendatins??Everything is still in there stock setup positions...Help much appreciated?

lighten up the rear on oil and springs (35 and greens to start) that should give u more rear grip.
subcultures are good for loose dirt. I just got some megagrids to try. I'll let ya know how they work when the ground drys a little more here.

front tires I run enduro's and add some weight to the frt of the truck (1/2 oz or so)

biggest thing for going straight is the 4* toe block. toes in ur rear arms and realy helps the kicking out goin straight. u can even go a little further with the .5 or 1* rear hubs

What is the best pinion and spur gear for low traction loose dirt short track.
I'm looking at able to easily control my truck around the corners and still enough torque and speed without lagging behind. There is only 1 straight about 40-50 feet, so high speed is not a concern here.

Everything on my truck is standard except I'm using 1/8 buggy tires (M3 bow tie all round).

I don't re-gear for traction. I adjust my epa on my radio, or adjust the esc for softer start if needed, you can even loosen the slipper a little to help.

I'm looking to get back in SC . Anyone racing the SC10 brushless RTR and is it fast enough?
