Holes in the chassis sounds a little extreme to me...especially if you have no way to balance it. Anyone else with any ideas?

Just like your real car's tire, they have a computerized balance machine to determine WHERE to add the extra weight so the tires can be balance....exactly the same concept on your spur gear....so buy the gears from HPI if 1 day they decided to created on or leave it alone.

No, that is with body, tires, radio gear, and personal transponder, no fuel in the car. Personally, I would rather have a well balanced, slightly overweight car than an underweight car having to add weight and mess up the balance.

In that case, with the changes I have made and the few others that I'm going to make, I have nothing to worry about.

I dont know why you guys are trying to compare weights over the net. Has anyone zeroed there scales out with a certified weight? Digital scales are so inaccurate you really shouldnt worry so much about weight. What do the other cars on the market weigh.
Also remember this:
Heavy car-stable and smooth
Light car-responsive and twitchy

Car still accelerates and corners great, but getting it into the 1700s cannot hurt it.

As for me, my gaol is not to get lighter, I have just made a couple of changes that I saw fit, in the process my car weighs less. It handled great before the changes, and I'm sure it will handle great afterwards.

I am not saying lighter isnt better. The only thing I can think of being heavier is a plus is a tank. Its just kind of funny how people get obsessed with the weight of the R40. I can see lots of weight to be lost in the drivetrain. Anyone tried any of the 3racing drivetrain parts?
Also there was a rumour of a ball diff for it, is that still on the drawing board or has it been scrapped?
I am trying to decide R40 or 710?

The drivetrain is very heavy at the 2 speed and the clutch when compared with other cars. In fact one of the specific improvements of the 710 was to lighten these areas. There is a Kawahara item available to get the 2 speed weight down and also to change to 0.8 module gearing. 3 racing has a lightened flywheel. I think it really needs a lightened clutchbell as well as this thing is comparitively massive.
However after saying all the above in stock form this car is awesome and accelerates really really well. My "heavy" R40 out accelerated some cars on the weekend and also carried a better top end than most.

AMG-I see you on the 710 thread alot- whats your take on both cars? I have been looking at the cost of both plus extra parts. Our nitro season hasnt started yet but its time to start buying. The price difference if I buy 1 car plus a spare car for parts plus extra spares of common items that break its a big price difference. Enough for 2 motors almost. Serpent has HPI beat in support for the car, and I really like the DRS rear end. Decisions Decisions
BTW the DRS is not a new idea- Team Lola used it on there race cars in late 60-70

Well, I think I'm gonna go out and actually race the car instead of trying to put in on a diet. I just weighed my NTC3. It accelerates awesome and is nimble in the turns and is at 1770g with full diameter foams, body and no fuel. That's just 20g lighter than my R40. Actually, I know the NTC3 is a bit tubby since I'm running the RDLogic aluminum diff cases. But after comparing the weight of the 2, I realize that it's more about what you do with the car and less about the car itself.
