Big Drak VTOL Conversion

There's now a Facebook group to discuss builds, successes and problems. Come join at https://www.facebook.com/groups/vtolhangout

Oct 5 2022: Added a nacelle and motor mount with an cutout for a 3x6x2.5 bearing on each side to avoid wear and tear on the printed part. Use a 3mm rod for the hinge.

The Nano Drak VTOL has been a success and I had a few requests for a Mini Drak version. The Mini Drak version has been around for a while now so next comes the Big Drak. I'm sharing these files but I haven't actually built one of these but others have and I will list a working spec below. I printed the wing mount portion and it fits the wings well. The tail mount is a beefier version of the one for the mini drak. Hopefully its beefy enough. Feedback welcome. There are 2 versions for metal or ABS plate depending which you have on your Drak.

The nacelles have a hole on the end that allows for an M4 bolt that sits just behind the spar.
The motor in the rendering above is 42.5mm w
