since the r40 is what you call "heavy", does anybody know the actual weights of the competitive cars ( r40, mtx3, tc3, 710/05). i want to know actually how much heavier the r40 acutally is?

also what kind of mods have you done to the r40 to make it lighter, with out adding new parts.... like shaving down things, or putting the dremel to the car.??

On my case, I'll try to switch to graphite as much as possible. I didn't shave parts though, I will not do that. I know that some guys completly removed the batterie and receiver case. They sticked the electronics with servo tape under the radio case to keep a clean look.

Some others remove parts like the handle and the foam bumber. With all those parts out, you save another couple of grams.

But I will not go that far. I'll stick with graphite parts, no shaving and removing. In my case, since I am not the greatest driver of all, it will be overkill.

But I am interested to see what other guys did to save some weight.

hmm the electronic thing is interesting. but i have gotten the graphite shock towers, and the graphite side plate. but i also added some aluminum so it is prolly right around the same weigth i had started

i aslo cut the lower front arms, where the shaft slides though, so that there is better suspension travel and i lose some weight

I would say that if you feel serious about cutting weight, your next step would be to replace the middle and the 2 speed shafts for the lightweight version + the new 2 speeds transmission.

I would keep those alloy parts out too, but it's your car

i am also planning on starting to shave some weight from my r40

first thing i did was swap the front diff for the one-way then the 2 speed shaft and mid-shaft were replaced with hollow units

now ive gotten the graphite shock towers

next will be a graphite side brace and switching to the smaller mtx3 style reciever pack and maybe titanium screws and the new 2 speed is a must have not for .8 gears but for weight savings which are especially beneficial from rotating parts

but ive been told there is alot of weight that can be cut out of some of the plastic pieces like the cover over the front belt and since when i bought the knuckles it came with a complete bulkhead i see no reason not to drill them out and see what happens

my friend was pitting next to hara at nats last year and witnessed someone drill a large amount of weight out of the plastic parts from haras advice

my local track is run what you brung style racing the only rules being small blocks and sedan bodies so the competition is tough and i could definetly use any advantage i can get especially if its free

Thanks, FastHarry.
Are you using the optional graphite parts for the rear shock towers... I dont know what they're called? The two extra pieces of graphite they give you with the rear shock tower.
I'm wondering if it has helped in the increased handling you spoke of.

amg, do you know when those parts are coming out, i already have the sideplate , but what about the tit. pivot balls?
Thats two positives for the shocks towers. Now I have to get them!

The 0.8 pitch gear box is lighter, but the advantage of the 0.8 pitch gear box is not only just lighter, the 0.8 pitch is FINER then the 1.0 gears and give a better launch power then the 1.0 (just like those elect ppl use 64 pitch over 48 pitch and over 32 pitch for better acceleration..)......thats why NTC3 are so powerfull on launch, then MTX3, then S710......all having the same gear box.
