I started to construct truck using
STC, recovered by Dave Taylor. I don't have ork truck though.Cabin is made from cardboard.
Firstly, I thinked about 4x4 sceme with wheels from 1/35 SU-100 model. But then realised that its possible to use electric engine from photo camera with 6x4 sceme.
I don't use Chimera's much, so it will be universal platform for Manticora, Hydra and Hellhound trucks.
Manticora will be something like Soviet BM-31 launcher
