I have looked at a lot of the bruder stuff.....but like you said finding one big enough to put all the guts in is the big problem.I wanted to use HL gearboxes and boards.I thought about a total scratch build....but it would be a lot of work.If i can find one big enough then a lot of it would be done as far as the main body and blade.

Tapkoote i tried clicking on the youtube post and got a page with a big red X and it said page could not be displayed.?

BIGMIG

Also as a side note i would like to find one with the older style tracks.
