Wheelbase options

[cautrell05]

Why were there several options for the wheelbase on the 10T yet there is little mention of using it for tuning? For example the noseplate has 2 sets of holes about 3/8 of inch shorter or longer. My B chassis has two sets of holes for the rear a-arm mounts and the mounts the OE mounts have 2 sets of holes. Just wondering.

I myself have pondered this same question. In my mind extending the wheelbase would greatly help out when it comes to high traction environments.

It would distribute the weight of the chassis over a larger area making it more stable. The only draw back is in theory at least the car would be less agile.

Indeed it is very useful to setup a 2wd offroad, though I have never tested it on my RC10T because I run it once every two years. With lipo batteries, a good idea would be to shorten the car up front and to lenghten it at the rear to reduce motor overhang and just move the whole weight forward. At least that's what I would do without hesitating. Let us know what your findings are if you try to fiddle with wheelbase. As J.Cyrul wrote somewhere in RCCA, it is much more relevant to think of wheelbase ( esp at the rear) as a way to ditribute weight front to back, than to think in terms of overall footprint. To try and and say it another way, by shortenig wheel base by moving the rear arm forward, you are actually gaining rear side grip because you put more weight on the tires, instead of gaining steering because you have in theory a shorter tunrning radius. Hope I'm clear...

Yea I understand what you saying and it makes perfect sense. I did notice after starting this thread that I must have one of the odd chassis. Mine was a #7001 kit bought in summer of 91.
This is the rear chassis. B stamp for what its worth.


First off for those of you gasping. I was young and STUPID when I cut the sides down. I admit it, worst mod I ever did.

There are two sets of stealth holes because its set up for mid motor, the usual front bulkhead holes and 6 old 6 gear holes. But for what ever reason It has two sets of holes for the rear a-arm mounts. I cant seem to find the manual here but the online manual only shows one set of holes.
I looked through all 500 listings on ebay for RC10T and out of all of these

as well as many others I never saw another one with two sets of holes. I looked though here abit the other day and all of them that I remember seeing were like the ones in the pic with one set of holes. Not saying there werent any I just didnt find them.
And just incase I broke another rule the above links were not to boost sales, simply a lazy way to reference pictures.

there's only supposed to be 2 holes per side for the arm mounts. the problem is that whoever flipped the trans for a mid motor setup put the bulkhead in the wrong place, which in turn moved the trans too far towards the front of the chassis, and the stock location of the arm mounts no longer worked. so new holes were added.

[cautrell05]

Ive owned the truck sinse it was new and I can assure you that I did not add the second holes for the arm mounts. All 4 were drilled, and countersunk. Ive been looking around for the last 2 hours and havent seen another one yet like this one.

well you can stop looking because you're not gonna find another one like that on here. that i can guarantee.

so when you took it out of the box, all four of the holes were drilled, countersunk, and anodized?

Wow, after nearly 20 years of racing dirt oval and mid motoring 10's even I am confused by that

Yep, all 4 holes were there straight out of the sealed box.

By the extra holes or the butcher job on the chassis?

Not all four arm mount holes, you might be thinking of the 6gear tranny holes- I have 3 of the early 7001 chassis NIP and they are all normal

and I meant the all the "optional" holes for wheelbase and transmission spacing- when we mid a car that is not designed for it it was never a pretty thing, and when there is an endless supply of new parts back in the day- we just cut and drilled away

[cautrell05]

OK I should have said all 8 were there. The six, six gear holes were there originally as were the original stealth holes. I added the reversed stealth holes but I did not add any for the arm mounts they were already there.

You can see where the chuck of the drill contacted the chassis on the second set of holes for the arms, and there would have been clearance issues with the bulkhead and the arms with the bulkhead mounted in the back which is why they are there most likely- but 1991 was 20 years ago and IDK what your age is now but memory can play tricks on you=

[scr8p]

the way it looks to me, when it was mid motored, you or whoever did it took that, and another chassis, and screwed them together using the front 6 gear trans holes on one and the bulkhead holes on the other. one facing one way, the other facing opposite. then all of the holes were drilled...... stealth AND arm mounts.

[cautrell05]

Those marks arent from a drill. those are from the washers that I had under the mounts to raise the inners and where they came loose during its basher days. they have been in the front set for a while now to move the rear wheels ahead. But from what I have seen in the last 2 hours of searching, the forward holes arent supposed to be there. Im 35 and I know my memory isnt perfect from 20 years ago but I know I didnt have acess to a drill press back then and there is no way in h*ll that I could have drilled them that perfectly spaced with a hand drill and the experience that I had at the time.
