here's a pic of my car shortly after it was built 2 weeks ago. I did a little photo spread for advertising the kit on a hobby shop website:

Can anybody help out and tell me what the internal ratio is on the R40. It will just save me counting the teeth.

Had a little setback with the car. For some reason I can't figure, the diffs started leaking. It just started?!? This, after I had the car assembled for about two weeks with no leakage.

Anyway, I went back in, cleaned everything up and gave it the 24 hour sealant treatment. I used enough sealant on the gasket and diff cases, that I'm pretty sure the leak will never happen again.

Engine should be here tomorrow, then the waiting for warm weather begins.

I don't know what RCCA had on the car when they came up with 1910.
Did you include body, foams and electronics?

Uhhhh.....yeah, the car had the foams and electronics on it. Why would I weigh a car without anything on it?

As for the body, it seems to be a toss up as to whether people weigh the cars with or without the body. I most often see them listed as "weight RTR w/o body". So thats how I weighed mine.

Thanks...

Since the cars are weighted with body at races, I would think that would be natural standard. But it doesnt matter in reality. Minimum weight is 1725 (including body). The body adds about 100 grams. Your r40 would weigh in at about 1855...

And yes, I am math-genius

Yeah, at the races the cars are weighed with the bodies, but when magazines or sites do reviews, they generally weigh the car without the body. This is because body choice and paint style(how many colors used, how many coats) can vary greatly, which would throw off the weight as listed in reviews.

This is why most people, outside race directors, usually list a cars weight without the body.

In any case, what I was saying is that there is some kind of oddity in the way that RCCA weighed the R40. For them to get 1910g for this car, while getting 1760g-1795g for other cars says that they did something different than what they did when they weighed the other cars. Cause even with the body, theres no way my car makes it to 1900+ grams.

any of you guys played around with different gearing from 1st to 2nd gear. I have written a speadsheet to know my options in different rollouts for different changes using different sets from each colour of gears.

Just wanted to know if you guys have changed this as I think a larger change is needed.

TIP for the rear body mounts.

The HPI Upper Arm/Body Mount Tree for the Super Nitro contains 2x short posts. Trim them down and also Trim the 3 hole Body Mount Cap for a perfect rear mount!

If you need even lower mounting, you can drill holes into the mounting cap above the first, then trim the first hole off, and trim the rear post lower to compensate.
