I am at the stage of trying to build a mount for a 20b to an Australian
Lightwing Speed 4000 fuselage.

Firewall mount dims are 715mm horizontal, 505mm vertical. Engine thrust
line  needs to be at least 160mm below the top firewall mounts for cowl
clearance at top of engine, and prop flange using RWS RD1-C re-drive
needs to be 1100mm in front of firewall.

Any help for the mount dimensions and general mount design would be
greatly appreciated

I need to know the positions of the hard points on the firewall.

Are you in touch with the other aircraft rotor heads in Perth?

Andrew,

Are you talking about putting a 20B in this?

Cute airplane, but stick to the 13B for this aircraft.

If you want a side by side airplane to stuff a 20B in, check out a Glasair
II RG.  It would carry it well if you used the aluminum end and intermediate
housings.  It should be faster than the Glasair III and fly better.
