Re: First attempt at a ladder chassis...

Thanks for the timely reply! lol I added some meat to the front of the car (from 3/8" to 1/2"), pulled the rear rear weight pocket in to an equal distance of the axle centerline, and added 1/4" to the front rear weight pocket (is that enough, or more needed)? I am very new to cube wei...

Re: First attempt at a ladder chassis...

FWIW, I did check again to make sure a car with a shifted wheelbase (cut off the back and move it to the front) would clear the curve on a Best track and it does clear. It's very close. If the Derbyworx Jig was used to drill holes I think the front would scrape. Maximum Velocity did a test a short ...

Re: First attempt at a ladder chassis...

That is excellent information! I will be going to the closest hobby town in next few days, and they have a very good selection of both woods. As far as the rear cut off, this car will never see a track and is just a "learning" build, so for sure not putting it on the front. It will be a sh...

Re: First attempt at a ladder chassis...

Ok.....put it on a diet and took off was much wood as I think could possibly come off. Did I go too far, not far enough yet, or about where a ladder chassis should be? I know it was pretty fragile taking it this far with a dremel and a file! lol http://i68.tinypic.com/2rpwgop.jpg http://i63.tinypic....

Re: First attempt at a ladder chassis...

Don't know where the cut limit, before losing any/all rigidness is, lol. I really do have a problem with jumping right in on new stuff, without knowing exactly what it is that I'm doing! I used stock wheelbase on this (leaving some wood in the rear), since I figured this would be a good test mule to...

First attempt at a ladder chassis...

Just messing around in the shop today, and thought I'd give it a shot. Still have some final sanding to do, but pretty happy so far. Any/All critique welcome...

Re: Straight running car

Usually and on a center rail track, that would be the case. The cant (neg) would keep the wheel on the axle head, and at the same time, keep the inside lip of the rear wheels away from the center rail. On center-rail-less track, I'm using the bend to cant the rears positive, to keep the outer edge o...

Re: Straight running car

We are running a no-center-rail track, and we had to build (per rules) 4 flat/straight tune. We used all straight axles, and we settled on +/- of 1/2" over 4'. But as an experiment, we built basically 2 more versions of the same car, but one with straight rear axles & 1.5* bent front axles ...

Re: under body clearance newbie question

BestTrack's center rail height is 1/4" according their website. If you have more than a 1/4" clearance once the plate is installed, you should be good to go.

Re: Morgan '16

Thanks fellas! These car's are worlds above what we've built in the past, and our hopes are high! I agree birddog, I wish our local pack's were a bit more competitive as well. My oldest made it through three different packs in four years, in his Cub Scouting, and we were able to go undefeated in pac...
