ok a play around with an assortment of bits laying around the house (main part a cheap old air freshener), at first i was going to make a aeronerf but then insanity hit, if you can make a tub fly why not turn it upside down and drive it with a big mono wheel !!!
well here we have it a mono wheeled tank !! access is from underneath
perfect for those low gravity planets that need to be tamed
Second pic has a pic of a standard 28mm scale mini to give an idea of scale.
(this was just a fiddle around this afternoon i threw some paint at)
ps the turret rotates
and this is still not finished..
