I just got a starter box for my Kanai, but I had to move the motor and wheel. Should the motors be toward the back for the box, handle side. I don't have my engine yet so I couldn't really check to see it the wheel is spinning the right way.

just make sure it turns your engine counter-clockwise.. so the motor must turn the opposite of the flywheel on your engine..

I understood what you said.. but some starter boxes may have the handle on the other side..

uDi - ABS is very hard on servos, especially when pulsating quickly.

You might want to be careful with that.

Cheers Aaron, i'll remember that. Do you think it's more strain on the servo than having it hold the brakes squeezed though? I thought it might be a little easier on it since it's only being stressed half the time that way.

Throttle servos are already on a ton of strain, but using ABS is actually a lot harder on them.

If you have it turned down to where the servos pulsates slowly, it isn't all that bad, but the faster it goes, the more strain it does.

gotcha. might turn the pulse rate down a bit then.

Horatio - you're probably better off with the 5925 (im no hitec expert) on throttle instead of the 5945, you don't really need 13kg cranking on brakes, but the extra speed of the 925 might be nice.

by the way, why don't guys run higher than 7-10k in center?

I was running 7k in my K2's center, and with the C5 it seemed to be offloading most of the power to the front wheels, and was probably loosing a lot of power that way... would a heavier center weight cure that, because it would force more power to the rearend?

Also annoying how the frontend pulls the car around corners, I want a bit more rear end slidey action so I can clear the tight corners faster.

how often do you rebuild your diffs?

warpig - Edit button bud..edit button!

uDi - Safest bet might be to turn them off; I don't know of any of the top factory guys that use ABS at all.

The easiest way to make an 1/8 scale buggy rotate (or slide as you were talking about) is to dial in more rear brake..again, a lot of the pros use very little, if no front brake, and use the rear brake to help the car turn.

doesn't sound like a good idea to put more back break in to me.. and I've never seen a pro do that.. I suppose it would depend on the track

I rarely ever see pros use front brakes, not even enough to stop the wheels from turning. Buggies are notorious for not having enough low-speed steering, and rear brakes will help the car rotate.

And you're right..drag brake is a no-no.

if you say so aaron.. I just haven't seen it.... 1/8 cars tend to work around corners with the proper setup.. and no rear braking whatsoever.. I've drivin tracks with many 180's and have no trouble with getting a tight fast line..

please explain to me a situation where it would actually function and not cause severe traction loss and be predictable.. even a mild run from the rear disc(s) will cause problems in keeping the rear locked for exit..

like I said.. I think a proper setup 1/8 can work around a corner like magic.. just like in sedan racing.. the same thing.. to get the rear to have the perfect break point where it just works itself to the proper exit position to keep speed..

it's all about the apex.. not rear brake.. IMO

It's all a matter of opinion. I've been at the ROAR Nationals all weekend, watching buggies slide into corners with the rear tires stopped and the fronts still rolling.

Rear brake will help the turn.

warpig - I rebuild them often enough, once a gallon or so roughly i'd guess.... I don't do it on set intervals, but it happens often enough (probably more often than most people)

Aaron - guess theres no harm in trying the rear brake thing, i'll see how it goes. My local track is really tight and probably more suited to 1/10 trucks. I was running in short wheelbase mode too.
