Yeah, I'm anxious to hear some responses about the car. Hopefully after this weekend (or sooner) we can have some reports.
Better hold off on that mtx-3

We race on very small tracks for nitro cars.

If you want higher 1st gear final drive ratio, you can opt for their 15T pinion and 49T spur. That'll make their highest final drive ratio to be 7.91.
Well, I don't know if it'll be the same effect as the stock 7.42 1st gear final drive ratio gearing on the MTX-3 because the MTX-3 is a pretty light car whereas the R40 is touted to be heavy... Something to consider.

heavy
I just bought the car today and I was real suprised to feel just how heavy the box was. I'm curious to feel how heavy it is with the engine and radio gear installed.

building the r40
I just finished building the rear end of the car. It took me about 3 1/2 hours. I think there are more parts on the r40's rear pod than my Veteq's rear pod. Although the R40 is designed a lot better than the Veteq when it comes to easy maintenance.
I made a stupid mistake because I was being anal about cutting off the flashing nicely. What I thought was flashing was really a nipple that fits into notches that adjusts rear belt tension. I figured there aren't any spare parts out yet so I ended up setting the belt tension to what I wanted and used CA to keep the part from moving.
The two speed shaft and the rear differential are really heavy. It's a lot of rotating mass. I'll see how it performs once its built.

Wouldn't it be a good idea to take a snap shot of your progress?
gosh, I miss my HPI...

Once its built it looks like it will be easy to maintain like changing out a rear belt or switching from a gear diff to a solid axle(hopefully an option part that will come out soon).
Instead of halving a right and left bulk head, the r40 has a bottom and top bulkhead.
To change a rear belt it looks like all you need to do is pop off the camber links and shocks then 8 screws to remove the top bulk head. The middle layshaft and differential slide up, so all you have to do is place a new belt around the pullies and slide them back into the bottom bulkhead.

I just picked up mine today...
I reallt like the way the parts look..everything looks real beefy..and the plastic is great..no complaints here..
Its got a german one way bearing in the 2 sp(and they are expensive),the diff gears are twice the size of the racer2's....
this car looks sweet...I will start on it tommorow,and keep you all posted..
oh yeah....I love the tank..and the pillow balls are thick,also..

Manufactured by INA. They are one of the most reputable companies when it comes to one way bearings. I've not seen other makes of one way bearings except that on the Tamiya cars
