Body Weight

I did some 1/4 mile speed testing with a body on the car, and without, just for the heck of it.

Stock SE, Purple Motor, red gears, red axle:

No Body:

2.475
2.535
2.463

Average ETA 2.491

With a body (average body weight is 7.5 grams):

2.794
2.755
2.765

Average ETA 2.771


Looks like running a body will cost you 3/10th's on the strip. Weight DOES matter. It also negatively affects handling, I'm guessing the added weight on the front wheels increases it's propensity to veer off to one side or the other, which sucks when trying to go straight. Also, while not tested, I'm pretty sure the higher the RPM motor you run, the more the added weight of a body will slow you down.

some HO slot cars use/can use lexan bodies which would be much lighter than the plastic hard bodies.

I've used those in the past, but they usually don't fit very well. Thats actually my next project, once the car actually works, is to fabricate a lightweight body.

I've wondered how hard it would be to vacum form my own lexan bodies in 1/64 scale.It doesnt seem to be that difficult once you have a mold of a body.
