The R40 is a different story... I get the kit and start assembling it only to find out that the one-way bearing is missing from the 2 speed hub. I called the hobby shop I bought it from and the guy said he doesn't have any in stock to give me. I call HPI and they said that a new one will be sent to me on Tuesday (they're closed Friday and Monday). I tried calling all my local hobby shops and no one has that part in stock (most only have the plastic suspension parts). I finally just placed a massive parts order with Tower Hobbies and requested UPS Express.
R40 questions:
1. Did anyone notice that the mid belt rubs against their manifold? I need to run the belt tensioner about 1/2 way down to make it clear. Is this normal or should I try grinding some of the manifold?
2. The tuned pipe mounting system seems very weak. Anyone have problems with it? If so, what is the best solution?
tnx

I couldnt really judge power vs others as I havent tried anything else on this motor specifically. But my car had what I thought a nice power-band and the sound was pretty much amazing.

performula,
That would explain why HPI didn't ask me for any proof or anything. They just said to throw it away and they'll EMS me a new one. It's very sad that even though they weigh everything (and ever put a huge sticker on the side of the box), they can still miss a heavy one-way.

how to
is there an easy way to remove the pinions?
EDIT: got it... just had to get the right wrench and a thick enough rag to keep from screwing it up.

Not really. Your better off just buying a whole new clutch bell/

As I have said numerous times, channel locks, and the HPI pinion tool. I have used this tool over 100 times with never a problem. I only have 2 clutchbells.

I see absolutely no reason to buy a whole new clutchbell as I got it just fine the way I did it, but I will be getting a pinion tool.

When I got pinnions I just got a new bell also. It makes it easier at the track when you need a quick switch. I had 3 different sets (yellow,green and the purple.)

Hey guy,
I ran the car today and have two questions:
1. Should I hear a distinctive shifting sound from the two-speed? I couldn't hear anything while I was running it.
2. The steering has a lot of slop in it and during acc and braking the car pulls to the right and left. Anyone have this problem?

I don't know about the stock 2 speed but you should hear the rpm's drop a little and then come back up. No one has fixed the steering problem yet.

2. There should be almost 0 slop on a new car.
