This is one of my favorite everyday desktop 1/35 scale micro rock crawler:  "ORLANDOO OH35A01 4WD Crawler".  Extremely tiny size R/C 4wd platform and a joy to drive on my table with lots of challenging obstacles to drive around.  Btw its pain in the ass to build since all the parts from the kit box is extremely tiny  and hard to build even with normal size finger.  Required some airbrushing work too. But at the end it was all worth it and nice to have truck. What i see on my table was bunch of muddy tracks, jungles, hills and valleys...this tiny trucks rolls and crawls!
