Awfully quite around here

Why would you ever put an 11 pound prop on a plan? <VBG>

If everyone wasn't so focused on using "pylon racing props", that would
have been achievable a couple years ago.  High pitch props make their
thrust at high speed.  Large diameter, low pitch props are what you need
for long, busy uplines.  Keeps the speed across the box down below Mach 2
so you have time to fly the sequence with out rushing.  I know the reason
for the high pitch props was to load the engine to keep the RPM's down
thus lowering the noise.  All one has to do is manage the throttle a bit
and the noise won't be a problem.  I guess another problem with large
diameter props is ground clearance.  Finally people are getting wise and
using fixed gear that should raise the nose another inch or two.

I flew a friends Midwest G-202 with a YS 1.40L swinging an 18X6 carbon
prop that weighed a hair over 11lbs.  Knife edge loops were no problem as
were multiple upline snaps.  Just imagine what could be done with a 9.75-
10.5lb pattern bird.

But what do I know... I'm just an IMAC convert who has yet to be
re-programmed.  :)

Flame suit on!!

The only sound I hear is "practice, practice, practice!" Been out flying
the Temptation with an OS 1.60 FI dangled on the front. Boy what fun.
Even if I never win another round or contest I will go to sleep dreaming
about the figure-9 with three 1/2 rolls going up.  


With the OS's YS's, Webra's and the recent Mintors, out there today
combined with 10lb planes we now have universal greater than 1-1 vertical
that does not lose roll rate going up. It really was worth waiting for!!
