Well, this is a bit embarrassing; I have to admit that summer and other shiny stuff happened between this thread's resurrection and your post...
I tend to accumulate projects on my desk until I can't take it anymore (read: run out of space to put stuff, mostly) and I put everything back in storage, clean the desk and start anew.
And I fear that during one of those clean-ups, the Drache got relegated back to storage duty...
But rest assured; I do plan on finishing it eventually.
As for your question; I have pinned the rotor outriggers into the fuselage, by very carefully drilling into the ends of the struts, whilst the pins were inserted from the inside of the fuselage. I used actual clothes pins, as the flattened metal heads act as a perfect stop inside against pulling the pins out.
The depth of the holes on the struts give the superglue enough purchase to avoid pulling it out there. The resulting construction is quite sturdy.
For the rotors, I plan on creating two sets; one with the original blades, slightly bent down, to represent the rotors in rest. For that set, I plan on using the original bits of the kit, but maybe will forego the most fiddly lasercut metal stuff, as those might not survive the rigors of the tabletop.
The other set, I plan to base on a disk of clear material, to represent the rotors spinning. For that set, I plan on scratch building most visible bits, but they can be a bit more 'streamlined' as most bits will simply be 'spinning' too fast to make out anyway.
Both sets I plan to attach to the outriggers with rare earth magnets, so I can switch them out, even during game play (heroes have to get to the artifacts before the baddies can airlift them out. Helo starts out sitting there, but as the game progresses, the pilots start the engines, etc. 'get to da choppa!'
).
The magnetic rotors will also help in storage, as the whole thing is quite cumbersome to begin with...
