Ouch!  I can't use it.  The prop will strike at a normal rotation.  So I
did some measuring ... and unless I'm crazy ... it looks like I need 30"
blades to be safe!  That's only a 60" prop!

Hey Guy,=20

How about some hard numbers?

1) What is your clearance from prop tip to ground with one blade
straight 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 when your prop touches the shop floor?

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

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

DM Rob

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