3D printed chassis with a body scavenged from the local model show (former RC car)21k motor and 48 pitch gears. It's a little over engineered to create the body mounting but that's my OCD lol. I think the black wheels look better!

Interesting use of the 3D printed chassis. Being intended for bracket racing, might be a good choice. I like that

it can be flown inverted like a stunt plane. LOL  All kidding aside, I'm interested in knowing how it works out.

I won't get in all the crazy machinations I had to do, after I accidentally deleted one of the photos, but I got all the images righted.

Hi Charles,

 

The chassis looks great as well as the completed car!

 

The black wheels really give the car "attitude".

 

May I ask, what type of filament material did you use to print the chassis please?

 

Thank you for sharing Charles!

 

Ernie

I did not print it myself but material is very dense and sturdy. I acquired it from Mike Swiss (he may know of the origin).

Charles got it from me.

I had gotten some from Bent Wrench, a local, part time raceway, that closed about 6 months ago.

I do not know the material, nor do I think that program is available to the public.

The seller did mention that before the gusseting was added, the front uprights were breaking off in crashes, even on his short, 4 and 6 lane tracks.

I have one of those chassis, so I'm interested in seeing how some people are using them. I was going to go hardbody for our Saturday evening

racing, but I am suspicious about it's durability.

Greetings Dave, I'm pleased to announce that the performance was good as a bracket car could be. I used my bench top band saw to cut off the pan material to be flush with pan uprights. Then used that removed material to bolt together with pan uprights achieving the desired width for body. The pin tubes are press fit into plastic material and counter sunk flat head 2/56 screwed to pan uprights. Due to the weight of the hardbody no wheelie bars were needed nor any ballast lead added. It launched well and stayed planted through the short drag track. The 21k motor is probably the right amount of power for a no-bar version.

Any pictures of how you modified the chassis?
