Looking good! hopefully Mr. Mike allows a few extras to be exchanged

are you making up custom dogbone(s) too?

This setup uses the aftermarket flux center driveshafts.

I haven't ordered them yet or I would have drawn them in there.

hey those are the same as a stock replacement so dont you still need longer ones? hpi measures pin to pin and those are measured pin to cup pin so they arent actually any longer than stock flux. i though they were also and ordered one a while ago to try on a flat chassis project i wanted to make, but it was the same as the 78 with the stock drive cup.
your chassis pics look good. must be a low kv motor you have

i just figured out you maybe made the chassis plates shorter to make up for the more small center diff. is that right?

Im using 2 of the rear drive shafts. When I started the project I centered the diff between the front and the rear and then measured the distance. I determined that 93mm was my sweet spot so I searched online for all available dog bones and universals of that size. It turned out the HPI drive shafts worked.

They arrived last night so I need to model them in solidworks and see how they fit.

must be a low kv motor you have

The motor is a 1600kv

Well you were right^^

The axles are too short. Back to the drawing board. I guess I will either eat the $40.00 and find some new dogbones or eat the $50 chassis and make a shorter one.

I finally have a few minutes to mess with the project. I decided to pull the CVD's out of my LST2 and what do you know.... They fit!! Well close anyway. The are just a hair too long and bind if they are straight. If I raise the center diff they seem to work nice.

I modeled them up tonight without moving the center diff yet. Here are some pics.
