Thank you very much for answer. I agree that the easiest way is to
design two different reduction gearboxes - also it will be more
reliable and (hope) lighter. Every gram is counting.

Our goal: two person in tandem VTOL aircraft, max tow 1200kg/2670lb,
power rotary 2x300hp, rotor diameter 2x4.5m/15f, wing area
4m2/44.4sqf, wing sailplane laminar airfoil 20%-18%, wing span
6m/18f, airplane minimum drag coefficient Cx0 0.018, composite type
structure. Machine can be fast if the problem with rotor flutter is
solved. We would like to use turbo compressor charged Renesis
rotary. Grateful for suggestion and opinion.

Sincerely,

Viktor




My kids and families were home for the weekend.  They rented
a DVD, which I saw part of before dozing off.
I think I saw your aircraft thoroughly field-tested
on the video Avitar  :)
