I am looking forward to seeing your build Walt! I'll be putting my Open chassis back together next month when I get a new motor and Ball Diff. Went a little crazy last month on RC orders so I'm laying off ordering this month. I'll be going with a Sensored 3500Kv probably a PN Anima, though if someone has another suggestion I'd be glad to listen. I've only had 1 sensored motor, so I don't know if there is a better option out there.

I did get my BoxStock chassis up and running on the new layout. I put KSK Soft radials on the rear and KS Medium low height fronts +1 20mm under a 2015 R8 body. I had to Super glue the front sidewall and about 2mm of the edge of the tire face, along with the side wall of the rear tires to keep from Traction Rolling in the high speed 90*s.
I'm still trying to get Front Tires figured out on my 04. Kyo. Soft (20*)LH tires worked well, but didn't last 1,000 laps. Don't have any Kyo LH Mediums (30*)but I do have some Hard (40*) LH that I'm trying now, and while I don't have any TR problems, it does have a bit too much Push on power in the high speed 90*s. That was on +2mm and I mounted a set on +3mm to see if there's less push while not developing TR. Might try super gluing some KS-M Mediums if I can't get the Kyo's to work.

Well I couldn't sleep last night so I dug through my parts bin and found parts to put my Open chassis back together with the Kyo 8500kv, and I don't know what I did, but it runs much better! It actually is quite good with Marka Soft Radials and KS Medium LH on 19mm and a 12C with the Factory Gear Diff and a 8T pinion. I couldn't use a top shock as the mount plate didn't get countersunk at PN, but it runs great without it, so no worries. Also I had to Heli-Coil the top plate damper plate holes as they both stripped with just one use! It's holding so far.
