Leo, i think it is possible that the "wing camera" already has a wide angle lens fitted?

anyhow, i updated the files on thingiverse, as the V1 with small wheels could drag the back of the chassis on the track when the track has elevations. 

on the rear, you can for sure use 1/32nd wheels. 
for the fronts, i used 11mm H0-wheels due to the reason that the camera holder could rub on bigger wheels when the angle of turn is bigger than xxx degrees ...
