ozy some of the veterans on our track sand down some parts on the clutch to improve its performance. i havent really studid what part exactly but you might want to take a closer look at it.

I concur with the 4 gear diff. The car needs it for consistency of the rear diff. Mine is much better with it.

My clutch comes in dang hard man. What are you endfloat and adjuster nut settings? I have .3mm endfloat and .9mm on the adjuster nut. I have not run on really high traction tho, your 45/42 tire combo seems to indicate your track is pretty high grip.

You could try taking the retainer spring (87097) that holds the flyweights and run without it.

ozysnake - do you have the part number of the kyosho 4 gear set?


TO ALL - what oil weight would you use for the front and rear gear diffs what you have the 4 gear set installed?


thanks !!!

hi all ,
thanks for the advise on the clutch i will try that,i tryed soft tyres 42 fronts and 40 rears but the car seem to go off at the end of ten mins on 45 fronts and 42 rears i think i could go all day but on saying this i have not yet race the car so it might be to slow with to much understeer we will see this weekend . as for the diff it came out of a v one r so i don,t have a part number .
cheers

Did some checking on the weekend on the HPI clutch for ya.

First up all the Mugen centax clutch shoes do fit the HPI clutch. There was a little bit of binding on the pins, nothing a little clearancing would not fix. So you could try the high bite Mugen clutch shoe.

Also the Mugen clutchsprings fit. You could try putting the Mugen high tension spring (gold colour I think) in to increase the punch.

hi ,
thanks for that amg . been a brisbane driver u would no what the grip is like at brendale (england park ) if you have race there it is high grip .mostly at tille events it real becomes high and there is a chance of traction rolling . don,t seem to have the problem yet with the hpi.
cheers ozysnake

Yep I know that track well. The HPI clutch should work nicely there without much messing around. Crank the adjuster nut down over 1.0mm.

You will have trouble traction rolling the HPI, but you can do it! The HPI team drivers recommend using the much more laid down front shock tower to reduce the chance of traction roll.

I just bought an R40, New-in-box, for 239$ and free shipping from a guy on ebay. Sweet deal huh?

I was at the winternats with my R40 and ran it inbetween my photography duties (i'm the webmaster of http://www.winternats.com ).

The car was awesome, but I had a bearing failure in my clutchbell. The smell flanged bearing came apart, allowing the clutchbell to extend out too far and lodge up against the chassis, this put such a load on my engine that it fried it in a matter of seconds..

Serpent has a package of high quality bearings that fit perfect, but it's $15 for two of them...

Just FYI. I knew the HPI bearings were low quality when i assembled the kit and I should have been prepared for this.

The 5x8x2.5 flanged bearing I think is the same quality wise. I don't think it would make any difference if a Serpent or a HPI bearing would have gone in.

BTW, nice job done on the coverage and website !

I've also been working with Wolfpack Radicals on the R40.

He wants to make other parts and will get with me later on that, but i'm testing a prototype 2 speed he made for the car.

it includes a titanium 2 speed shaft and TC3 2 speed that drops about 20 grams of weight from the car (and it's all rotating mass).

I've got to give him some measurements from the car tonight and discuss further information with him, but he says he'd put it into production if there's enough interest. The TC3 2 speed is much MUCH smaller in diameter than the HPI 2 speed.
