IO-720
Posted: Sat Feb 18, 2012 12:04 am
Had the pleasure of seeing Brent Brown's SR w/M14 (@ Bountiful airport Utah)
land last week. Sitting at the airport waiting for my friend to get back
with my brother from a cub ride I heard the call sign "experimental ###SR"
and jumped in the truck to see if it was him coming in. Nice dusk, non event
landing and he rumbled up to the hanger and took his time shutting down. He
got out grinning and couldn't say enough about how good everything was going
with 7 hrs in the air. Brent had had some trouble getting the engine started
initially apparently a mod was machined into the air distributor (unbenownst
to him) for starting and was holding the face plate a couple of mills off
from sealing and while a majority of the air was going to the correct
cylinder, there was also some air going to all of the other cylinders too -
causing it to turn less than enthusiastically. Brent found the problem by
measuring all of the components and adding them up - and finding the
discrepancy.
Brent likes the Radial and says it runs like a sewing machine with so much
power he doesn't even use full power on takeoff.
Here is the question - Brent mentioned that I ought to consider going with
an IO720 - Looking out on the net it seems like it weighs about 600 lbs
compared to 500 for a fully rigged IO540 - Any Thoughts??
PS
Having never seen a flying Super Rebel or ridden in one and having bought
into it lock stock and barrel - I gotta say that just being in the vicinity
is like putting a fire under me! - Working on my first wing spar woth
renewed vigor.
