Thanx for the Tamiya colour numbers. I checked, and I, indeed, got those around.
4100kv sounds exactly right. It’s a KOH buggy after all. It shóuld be able to get to some real speed. For now I use the 21-turn brushed motor that came with my first, rtr, Wraith. Also just 2s. After running-in, I’m thinking LRP sensored K4 8.5t. It’s great in my “crazy speed Wraith”
I dìd run into a slight problem with the build, though. Since I wanted to use the Dig ànd the 2speed, I wanted to use my Carson reflex wheel, because it’s my only set that has a proper 3-way switch for channel 3.. well .. that receiver is a huge 6-ch box. ( and my Spectrum 3-channel , with the tiny yellow box HK receiver, only has a 2-way switch) no way that big Carson box is going to fit into the small-ish receiver bay in the front. Verflixt!, dickes Ei.
However. While building, it became clear that the front of the car is quite roomy, so plopping a receiver somewhere under the front bonnet won’t be a problem. And if push comes to shove, I can always stick it to the passenger seat, camouflage it as some luggage, or something. I’m not going for water tight anyways. And ìf I insist on dumping the car in puddles, there’s always party balloons. Works fine for my hydro’s, should work for the car.
For the rest of it, the build has been an utter joy. Challenging here & there, because many parts can go in the wrong way (say, the shifting forks, or the gears..

and there I was, wondering why I couldn’t close the gearcase without blocking everything from rotating.. ) But ultimately rewarding.
