I noticed mine is rubbing also. I had a custom made gear adapter and oneway made when my stock one was defective and HPI took over 2 weeks to respond to me.

I thought maybe we had measured it wrong, but when I did finally get my new one from HPI, it also rubs.

clutch adjustment question. It seem that my engine has to rev really high before it starts moving. I know that I have to add/remove shims to get the correct "play" in the clutch. My question is, do I add or remove shims to make the engagement earlier?

Also, sometimes the motor will rev like I have a huge cam like a lumpy cam in a V8 would. What might be causing this, and what should I adjust to correct it?

EDIT: i just found on the trinity site, that the eratic idle may be caused by a leak in the carb. I'm assuming that the leak would be from where the carb connects the motor. Is there a good way of testing if there is a leak or not? I know with cars, spraying some alcohol in the suspected area would cause the idle to bump up a little if there was a leak.


TIA

SMZ… Like InitialD said, try first with the 87095 and if your clutch still engage to late, then add more shims to make the engagement earlier.

Has anybody else had a problem with the 2nd gear housing rubbing against the back of the 1st gear spur and oneway holder? Mine rubs a fair bit, was thinking some shims in this area may help.
Or you can tap the oneway bearing in the first gear adapter a little to one side

Me and 4 other top drivers at our tracks have had the 2 speed rubbin gon the gub, but it doesn't effect the cars. If the car is new just make sure to clean it out until it's done rubbing. That way the metal shards wont scare the clutch shoes. After that you'll be alright.

Default R40 with Side Exhaust?

Hi

I just got the kit and not sure if I can use a side exhaust engine for the car?? if I use a side exhaust, do I just get a normal mainfold side exhaust one?? or it needs to use a special one??

Regards

Is that new light weight super chassis worth the money? I just ordered the graphite shock towers, light weight shafts. What next?

Since most of the modern day cars are designed from the start to use rear exhaust engines, chances are you'll need a special manifold for the rear exhaust. Check out some of the Yokomo manifolds that they use for their older RTR cars. www.yokomousa.com They bend up at an angle before curving, so that they clear the rear bulkhead and/or side braces.

If anything will let you use a side exhaust in the R40, that probably will.

Good luck...

jscamry - Yes it is from 3Racing.com. I haven't weighed it but in all honesty, I think the graphite part is the same if not heavier. I was thinking about using a AAA rx pack and removing the upper battery case and just using velcro or shoe-goo to secure the pack to the bottom plate.
