Hey Guy,=20

How about some hard numbers?

1) What is your clearance from prop tip to ground with one blade straight=20
down and the plane sitting "level" on it's gear?=20

2) When you lift the nose, how many inches off the ground is your nose wheel=
=20
when your prop touches the shop floor?

I ask these questions because you kept using the term "normal rotation". I d=
o=20
not know how much Velo experience you have but "normal rotation" for every=20
other plane in the universe and "normal rotation" for a Velocity are totally=
=20
different animals. :-)

For example, on my XL RG the answer to question one was 6 inches and questio=
n=20
2 was 18 inches.  That was plenty. Even less would be fine. Would like to=20
hear your numbers

DM Rob

PS Bear in mind that the with the RG the nose gear spring does compress and=20
you will gain another 2 inches or so of ground clearance once you have weigh=
t=20
in the front seat.
