ThunderbirdJunkie's 3200kv 540-size motor with the right gears will drag the back bumper all day long. His quarter panels are destroyed as a result.

You're geared wrong.

Try a 24t pinion and 81t spur.

any one running 17mm hex's ..... just looking on ebay and theres alot more option on brands for the convertions .. im running stRC ones got them back when they first came out and im FAR from happy with them ... any one running the dynamite , LW-hotracing or aka ones ????? what ya think of em ..

Hi,

Thanks for the info on gearing. I'll try this gearing on stock Reedy 3300kv motor.

Hi,

Today found my SC10 rear left tyre wobbling when at full speed (no load - lift up the truck from ground). Any tips what to check and what to do?

I drove my truck for the first time on Saturday. TQ'd and won against all the 2 and 4wd SCT's. I had a blast driving the truck.

How do you know when you need to back off or tighten up on the diff and the same thing on the slipper?

Remove the tire from the vehicle. Grab the shaft and wiggle it. If you get alot of play inside to outside and up and down chances are you have burned up a bearing the rear hub. Very common with the sc10. If you are running a bigger motor. Or are very fast with a stock 17.5 motor you can go thru bearings on this very quickly. The best thing i have found so far is to switch to the .5 or 1 degree b44 rear hubs. They cost about $25 bucks for decent aluminum ones but save you that in bearings in the long run. I was changing bearins every 2-3 race days in the rear. Now i do about 1 out of 6 instead.

Love the red and gray setup. Ran it for quite awhile. Leave the 30 wt oil all the way around and just play with different spring combos. Are you running the same pistons as the ft kit? I just change the spring not the oil its alot easier and alot quicker. Its amazing how different you can make it feel just buy playing with the springs. right now i have green in the front and blue in the rear. Ive been racing on a very tight short indoors offroad track. Handles like a dream. But when i get to a larger track ill go right back to the red and gray. Silver and green works great to but i run that normally outdoors with 30 front and 25 rear.

Mike,
I have the 1.5 degree blue aluminum rear hubs on my truck. Should I go down to the .5 or the 1 degree? They are different amounts of toe in on the rear correct?

Thanks

I check both side and it seems to have little play up and down and inside to outside but the strange part is that only left tyre vibrates (wobbles). The right one is as steady as brand new.

Could it be because I pack the differential with black grease? I mean really pack it.

I only see this after I pack it with black grease.

Possible. But i would tear it apart and inspect the bearings, make sure everything is ok.

Also shine a flash light on the diff on the side that wobbles while its under power to see if its wobbleing there, you may have one outdrive that that is bent a little or where the dogbone rides is wore out.

You could try to balance the tire your having an issue with...i just glued up some new tires and 1 is more out of balance than other. its possible through running the truck that one could get more out of balance than the other over time.

Will chk out the balancing. My LHS guy said could be the insert unbalance.

Switch the tires to opposite sides and see if the balance issue moves to the other side?

How do you know when you need to back off or tighten up on the diff?

When I built the truck I built it according to the FT manual. I noticed last night that it called for a 3.5 degree rear toe block. I also installed 1.5 degree FT blue aluminum hubs so i had 5 degrees of toe. Maybe that is why my truck was kind of twichy down the straight away and also why it wanted to come around on my so easy.
What do you guys think?

Last night I put the 2.5 degree rear toe block on with my 1.5 hubs.

What about cutting vent holes in the body. Will that help keep the front down over bigger jumps?

Thanks

I run the 3.5 degree toe block and 1 deg hubs without any problems. My SC10 is stable on the straights. Anything from 3.5 to 4.5 degress is good for medium to low traction surfaces. You will want to reduce the toe on higher traction surfaces.

In terms of control over jumps it is really about throttle on the launch ramp. If you over throttle the front will fly up. You have to learn to come off the throttle as you hit the face of the jump to keep the nose down. If you watch some of the Pros they can control the pitch of the truck well without holes.
