Karl,

So what then is the required clearance for the trigear ? 
My 2-blade Woodcomp is 69.5 inches with a ground clearance of 10 inches. 
Cheers, 
Karl 

To test for 1.5g worst case, let the tyres down, load the aircraft to 931.5 Kg
(2025 lbs) and measure the clearance - there should be some!

To test for static clearance at MAW with tyres inflated, there should be 180mm
(7 inches) of clearance.

Remi,

For sure the Monowheel with the standard 62 or 64" prop is far from complying 
with
that requirement! 
Remi 

The reason the XS had it's engine moves 1.5 inches higher than the Classic was
to alleviate this problem. In mitigation, the Monowheel does not really 
"rotate",
but takes off and lands in the three (two?) point attitude.

If you are looking at "non-compliance", look no further than the seat belt 
mounts!

Nigel
