Will 85 grams be too big of a problem? I'll run LiPo/13.5 if my externally set budget allows.
So, my choices for a chassis right now are
TC4 new or used
used TB Evo
Belt drives I cannot find one that will fit this controller without mounting it vertically or to the body.
As a last resort, I'll run 1/10 pan car. That should have plenty of space.
Any suggestions on chassis?
Sounds like an old BMI TC3 or TC4, whatever is cheaper (TC4 is more durable) will fit the bill. Don't know about any of the others, they may be good too. The BMI chassis was great and has all that room on top for stuff. 85 grams is not too bad although up that high will mess with the CG. I would guess the TC3 is about 1/2 - 3/4 lap down on the belt drives for a typical driver, and maybe another fraction of a lap with another 3 ounces up high.
Another possible option is a custom mount you fab for one of the belt drive cars you like. You don't have to be stuck with the OEM deck, just drill out holes and fab something out of plastic for a mount.
