Huh.... mine body after putting the fifth body post don't deforms going at the backstraight at more than 90Km/h... so probably will be fine. Downforce is constant and don't struggles your body.

If without this conversion, and we run smaller front than rear, what are the effects on the drive ratio?
Amazing! You and your friend spent most of the last 2 weeks bashing the crap out of me about my posts on this and it seems that you did not even bother to read them, not cool. The overdrive ratio sheet that I posted a couple pages back give you the complete OD Ratio for all tires diameters using a 16/19T pulley combination. Also there are some explinations about the benefits of running the 16/19 combo. As I indicated before if you run a 3.5mm split you maintain the origional drive ratio.

If without the conversion you run smaller front than rear tires the effect is that you will have more drive to the rear of the car. This will make it feel more like a 2 wheel drive car, basicaly less planted, more dificult to drive, can not get on the throttel as agressively while cornering etc. If you have more questions feel free to ask and I will try to answere them.

Default Floating rear + Slipping one way bearing

Hi Guys,

Had a good day today, won my clubs 1/10 200mm race.

One of the cars was an MTX-2 with a Lola body with a rear floating setup. His car is PLANTED on the long sweepers.

Anybody know if you can get this setup for the 3?


During the heats my 2 speed was acting strange. It would kick in, then out then in again etc. Then I'd loose drive for a second, then it would kick in again!!

I traced it to the one-way bearing. Can you clean these out & re-oil them or is it shot?

I use VERY light oil with this bearing, I've heard others talk about proper one-way bearing oil, can this make a difference?

All the best

The act on the long sweepers with floating body mount is characteristic, all the downforce created by the speed and body is directly transferred to the wheels, not to the suspension assembly as almost all touring cars do (Try to drive an 1/8 car without the floating body system.... if you have guts )

The abnormal shifting would be caused by several things, first to check is there's any kind of debris, grease, dirt or 'lord only know' on the shaft or the bearing. Best to do is a generous shot of brake cleaner, motor cleaner or similar and then apply a little dab of Serpent one-way bearing oil to the bearing, not on the shaft as many do.

If continue shifting badly check your 2nd speed shoes, should be even spaced into the bell and clean all the residues on the bell prior to reassemble (try to not put oil on the clutch shoes nor bell).

Sorry little confused are you saying that all is required is moving the 16T pulley from the front and replacing it with the 19T rear pulley?? So this requires a larger front belt only?

I use AE silicone diff lube with excellent results. Racers Choice also has a oneway lube.

Don't use regular oil or grease because it's too slippery. They won't allow the rollers to lock properly.

Default Speedmind foam tires

Today I tested my first set of the new Speedmind Nitro TC tires.

Speedmind always had good foams for electric cars, but no front compound like the GRP tires.

Recently they released the "Beast" which is their new front tire.

I ordered a set of 42/40 in 26/30mm.
I am totaly sold on these tires.
They wear better than the GRP's, they seem not to chunk as easy and they have the same if not better traction.

Considering that I bought them for $12.95 in the US is the best part.

If you want to know where to get them, shoot me a PM and I'll let you know.
I won't post it here on the board with respect to the sponsors.

For more info on the tires, check

OK, I would be pleased to hear your results.
We also take our club races seriously - probably too seriously.

We ran a 20 minute final yesterday using 35 shore front and rear, and with enough ride height to do it, I thought.
The car (VoneR) performed really well, but as you might imagine, rear tyre wear was considerable. There were quite some sparks coming from the rear end near the finish.
We have entered a three hour Enduro for next weekend. Our part will be three x twenty minute sessions.

Few of our club members had similar problem to yours. When i checked on their 2 speed clutch shoes, found that they werent properly adjusted (refer to attachment sheet from manual) at the two steel balls which wasnt compressed enough to hold the center shaft nut.

congradulations !!

i suggest you to check on the shoes adaptor to see if there is any worn spot. the worn spot will make 2nd speed shifting funny.

I would suggest to replace 2speed shoes, screw set and the adaptor nut as they are not expensive.

Sounds great Stefan, are the offsets similar to the FAST tires also?(Is it a direct fit?)
