hehe if you are turning to the Right then its not your batts... cause Pro4 batts are on the Left side. most likely your wheels are not Cambered and Toe'd correctly Plus your servo is probable to be not on Zero with your Controler... try have someone Camber it for you in your regular Shop and then ask if they can Zero the Streering for you... Its difficult to Zero the steering if you have no proper equipment for the Cambering.

These are Pics of what I did to my Pro4. I sliced the whole Length of the Top Deck into 2 peices so giving it more Flex. I dont Use the Middle Stiffiner that holds the upper and lower Decks ( I have no Place for it Anymore, as I have Splitted the Upper Deck that holds the Top part of it. hehe )
I have also Bored a rectangular Slot on the Front side of the Chassis.
I also shaved the Aluminum Shaft to my Content...
Oh well.... its up to you to experiment on your Kit. I did what I like and it works for me. It Got me a Trophy on the Nationals in Cebu for that Setup.
Or Maybe its my Driving?..... hehehehe Joke!

Cheers!
Honestly.... this radical modifications makes or breaks the next generation of Kits... should the manufacturer's find out its a good thing.
For me... I just liked it...

Wow!// big mod...

what did you cut the CF with? It looks pretty even in those small pics. Do we get any larger detail? Is that a Hara top-deck that you've modded?

How thick is the CF.. standard chassis?

well done!

here's something I came across on RcMart:
Spool adapter that fits the one-way unit.

so, that should give you the 'spool' action on power and the off power one-way action without the individual tire roll?

It should just give you the rear (but straighter) breaking of a oneway, but you maintain the turn-in of a spool.

I'm not so sure that's relaly all that useful yeah?

Locking your one-way so that you lose brakes (one of the biggest advantages of using a spool in the first place), but losing one-way action for turn-in?

Spoosl have horrendous initial turn-in(off power). It's exit steering that they excel at. Which... er.. is basically the same as a one-way anyway which if for all purposes and intents "locked" in drive on corner exit. So there's not much to be gained right??

A one-way gives you initial steering because it allows the outside wheel to track faster, to complete its traciton circle. A spool means the both front tires are rotating slower than they would, if they could complete their own traction circles...

I'm not too sure i understand WHY... lol!!

anyone care to enlighten me?

yea angry asian gots it

i think the name of the item is just misnamed because it doesnt do anything good for the one-way in traction of the circle nor is it better than a spool in braking

if it really does DO somthing tell us

The HPI unit is nice and light, but because it's all aluminium it does wear out quite quickly.

TiR do a nice unit with either replaceable delrin outdrives, or a steel version. Both look good to me, but i've never used them.

Shooter came out with one a while back too but i've not seen them around locally.

As for advice, make sure everything is shimmed well. If you have old style diff gears lying around then buy the alu reenforcing plate to avoid chipping teeth. The new 1.1v gears are much stronger. I'v enot had a problem with them.
