All these update possibilities made the 8110 UnimoC the best possible set for my taste: it's true, it is weakly motorised, but all the time I felt like some solutions were intentionally put that way, to make it easier to upgrade. (the 1stud longer axle for the direct/mounting of an XL-motor, the position between seats in the cabin for a 11stud steering-holder, and so on). I think, one of the last 8043's from Hungary is on it's way to me (no sources in Serbia at all!).
It would be great to have an official RC-mod kit similar to the idea of the 8293, maybe one remote, one receiver one L (or even XL) + one M motor, a battery box, the basic gears, clutches and so on. I think it should make even some cuusoo sets easier to pass the official part for being not so expensive in "basic" version.
