<DIV><FONT face=Arial size=2>Steve, thanks, but I am *no* expert. MUCH I
have learned from others who have shared what they know, and I add my piece to
that mix. What I have found, without exception, is that the current crop
of 1.60's, 1.70's, both 2 and 4 stroke, are COMPLETELY capable of hauling 5kg
models in FAI with three blade setups. Period.</FONT></DIV>
<DIV><FONT face=Arial size=2> The choices are pretty subtle,
and not real obvious unless you're willing to try "weird stuff"....like the
Master Airscrew 16 x 10. Proving to be a great choice. So is the
"GRS" (looks like a Mejzlik) 16 x 11, and the Mejlik itself. Then, of
course, the APC's, but Fred refuses to retool and reduce the 13 pitch three
blade (Completely understable considering the "fickleness" of US).
Lockharts' repitching works VERY well, and I've had the 10, 11, and 12
pitch. All work very well on the OS 1.60 piped.</FONT></DIV>
<DIV><FONT face=Arial size=2> We need a Webra expert who had
experimented to chime in here, and they're probably contesting today.... but
I've had the Webra 1.45, and the only three blade that *IT* would turn well
was the Bolly 16.5 x 10 !!! And that was un-piped on a Bolly MF 590 R
muffler. With a TP, it would probably do okay on the Bolly 16.5 x 12,
but those props are lighter motor-loaders than the APC and
Mejzlik.</FONT></DIV>
<DIV><FONT face=Arial size=2> SO far, the MA has the
lightest load, most effective braking, and best overall
speed/accelleration.... but then again, it probably is not a good enough prop
for us to use consistently.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If I had a Webra on a Pipe with ground clearance
issues, I'd get the MA 16 x 10 three blade in a heartbeat. $18.95
delivered to your do from Windsor propellor. If it *didn't work*, you
can sell it to me....</FONT></DIV>

diameter, and you would need the pitch so high, it would make the airplane
too fast.</FONT></SPAN></DIV>

I have a definite ground clearance concern. A 17" just barely clears
