Re: Weight placement question

Thanks again. I'm going in circles as to whether I want to just leave it be, or if I should nix the dome and instead start carving out the bottom for a 2 oz plate. If I carve out the bottom in front of rear axle where the dome currently is and put a 2 oz plate there, I can get 2 advantages; 1) I can...

Re: Weight placement question

I wouldn't use Domes. They're too restrictive. However, if you have a COM of 3/4" in front of the rear axle slot I'd say you're in good shape as far as that goes. If you do everything else following science you should have a competitive car. Thank you. I temporarily put on some wheels/axles an...

Re: Weight placement question

Updated with some images/descriptions. All options put the cog between 3/4" and 1". I'll probably be able to adjust it a little further at the end with some putty, as I'm just under 5 oz (assuming I don't fill in any un-used holes, which of course could change everything...) https://i.imgu...

Weight placement question

I've cut my car to a flat 3/8" or so and with wheels and axles it weighs 1.5 ounces. I drilled a few 3/8" holes for cylinders/domes in the rear, with 2 in the very back, 1 about 1/2" in front of the rear axle (I don't recall why I didn't place it closer to the rear axle) and another o...

Re: Cutting grooves in side of car where wheel edge might touch

Thanks everyone. This is just something I saw a few people online doing, but wasn't seeing the masses do it, so I wanted to see if it was something I should consider or not (in general, not specifically related to anything else).

Cutting grooves in side of car where wheel edge might touch

Hi. First post here. I wanted to ask if anyone does anything like this? This is the front of the car looking down at the top. https://i.imgur.com/OQYfDwz.jpg I can't decide if it makes sense, or if the edges of the wheels shouldn't be near enough to hit the car body anyway (and if they are, the leas...
