Somebody has some experience with the car on a indoor carpet?


I'm tempted to sell my loaded TRF for a B44 because of the grip roll I have with it.

It's even so that lots of people are using schumacher stagger ribs on astro and carpet because of the grip roll.

its the same on carpet mate. i had yellow mini spikes on the front and yellow mini pins on the rear because thats all i had and it stuck to the floor and went where i wanted it to. if anything i had to much grip and it turned in to much but didnt loose the back end at all and i didnt roll it once. i put about 4 packs though it to test it. and it didnt roll once

Maybe I sould give the B44 a try then :D

at the weekend i placed 4 places atleast higher than i normally would and i dont think i was drivin that fast as i was scared of breaking it so it is a good car

Somebody interested in a loaded TRF (all options possible with spares "almost enough to make a second car" and a pro painted body?) :wtf:

Maybe because you were making less mistakes?

you say you were running yellow mini`s on a wet astro track, i would give you a weeks wages if you could get any car to grip roll:rolleyes:


And you say it has more steering lock than the BJ4, how much do you need?

The 501X has the same suspension geometry, the same shock setup and a very similar weight distribution to the B44 - I think your 501X needs a setup change if it's grip rolling where a B44 isn't. :)

I don't have the B44 yet so I can not compare it. In our club everybody is racing with stagger ribs on the front because the grip roll is to extreme.
We tried all the possible set ups etc... (even with internal shock limiters)

Cars like the XX4 or BJ4 don't have this problem with mini pin on the fronts with the same set up?

Have you tried the same setup as the BJ4? Remeber the 501X is a copy of that car, with belts. Not trying to convince you to stay with your Tamiya - but I'm sure the car should be tunable as any others - especially the bj4we.

I tried the exact same setup as the BJ4 without any luck.

As you can imagine the steering with stagger ribs is not good enough to race in a good line and with mini pins the grip roll is always there so you can not push the car at all.

The only thing I didn't try so far is using mini spike's on the front (carpet and dry astro)

I don't think I'm going to sell the TRF, it's a beautifull car (especially with all the blue stuff on it)

To avoid grip rolling, you can go radical and put a thin layer of CA glue on the outside wall of the front tyres. It is VERY effective for taking out front grip, believe me.
And if you went too far, use a sanding drum on a Dremel and take off the CA. Easy and reversible :cool:

We tried to cut 3 rows in and outside of the front mini pins and even than we had grip roll when we push the car a bit.

Glueing the side is less extreme than cutting the rows I think?? :confused:

Wow, I'm a bit dissappointed that the B44 is so much better than a BJ4WE. I was perversely going for a BJ4WE to 'have something different' and I prefer the shell anyway (I know they are interchangable).

Nobody has said why the B44 is better, from what i take from the thread, those who have broken the BJ4 would do so with any car they were given.

If you go for a BJ4 you will not be disappointed!

i'll second that :D

third:D

Obviously I won't see the difference at this (club) level. And I get the feeling I'll be a thrasher in 4WD so steering lock won't be important.

Elliott.

Once you have the magic setup on the BJ4, you dont touch it, its just fast anywhere, even when i drive it (well fastish)

has anyone done any back-to-back testing with the bj4 against a B44??

is there a massive difference in the way they drive?

just found this pic of one with a team azarashi bodyshell, looks great i think...
