You want simple, what's more simple than using you'r existing chassis. It may look like an afterthought, but it works. And the balance is fine.
Never been a fan of mechanical brakes in electric cars either, I like the K.I.S.S. approach.
I got into electric because it's fun, and requires less maintenance. I don't want to check for brake fade and clutch shoe wear.
I'll admit I'm extremely biased. I've never held a Tekno product in my hands.
Since v3 the buggy could use standard pinions.. no long shanks.
The tekno motor mount system works fine and provides a lower COG to boot.
No tekno kit requires mechanical brakes.. it's an option
The use of the traktion drive is also optional and a good one.
With the traktion drive you don't need mechanical brakes or you can use them, your choice. The traktion drive helps tame the initial torque of a brushless motor on your entire drive line (diffs, shafts etc) making everything last a LOT longer. The traktion drive can be tuned allowing more power to the ground, I'm not sure how much more 'kiss' that could be :P swapping out clutch bearings every now and then I wouldn't consider much in the way of maintainance. Again if you don't want that, just run any standard pinion and be done.
Either setup will get the job done, the tekno has a much lower COG with the battery actually recessed into the chassis and weighs a little less. At this point both have very similar layouts and features if you run direct drive with a standard pinion.
