"Soviet" Prop Weights
Posted: Fri Feb 17, 2012 9:22 pm
Well I'm "up", but the "about" part really tires me out quickly!! Over did
it a bit by driving out and picking up FOKM's owner at Midland airport
yesterday, so he could fly her out of here on wheels back to Ottawa. My mind
says get in the shop, but If I'm smart I think I will stay close to the
couch today!
I guess the V520 will make a great float prop at 106 1/4"!? Might have to
find out more about it, such as to whether I could whack 5 " off each end
and readjust the pitch angles to make up for the lost blade surface! The
other concern is that according to the prop log, it looks like, it weighs 49
kilo's = ~108lbs! Unfortunetly, with the current state of my body I can't
lift it onto a scale to comfirm this!!
Anyone have a weight for that 94.5" wood V530 propellor on the M14P as
installed by Murphy?
Thanks,

V530Hi Wayne !
Glad you're up and about !! Hope it wemt well, and you ARE
taking it easy !!!! ;-)
I was told that prop was 96", but it seems that was an inaccurate
translation, and 94.5 is closer to reality. With the shorter SR2500
gear legs, it definitely made me nervous, but there was no problem
with clearance with the longer legs. A side benefit is that it lands
much nicer with the longer legs - I guess the higher angle gives a
better stall for smooth 3 pointers. I never had enough nerve to try
wheel landings - in fact, for a long time, I took off with the tail
low, just to be sure ! (and that was with the larger tires ..)
I spoke to several M-14 pilots at Sun 'n Fun, and the consensus
was as mentioned in one of the recent posts - the 2 blade prop that
is on the SR3500 is not the best prop for that engine, BUT it IS the
cheapest (at about $6,000 !). Everyone who had tried them agreed that
the larger diameter 3 blade MT was a FAR better prop - BUT it was
over twice the price !!!! That situation may have changed, but the
price and the extra length were both major deterrents for several
SR builders ....
Not sure how you'd make out with that 106"-er ..... you
might indeed need some really big tires !! ;-)

part! The prop I have is a V520/7 not a V530. Mine is all aluminum, the
longis wood. Measured it again this morning and it is definitely over 106"
andthough. Each blade length from tip to the hub collar is 46 inches long
totalthe hub is just over 14 inches outside collar to outside collar, for a
bladedof 106" +.

Those numbers are supposed to be with the new gear legs and the two
newinches.prop. My understanding is that the V530 is 2.4 meters or about 94.5I am looking at the MT 3 blade prop that is 98 inches.

Scott, are those numbers with the M14P's 2-blade wooden prop and the
itSR3500 gear legs??? Do you know the length of the M14's prop?
I ask, as I'm now the owner of a partially completed SR, and if I take
lesstoobtainedcompletion will be most likely installing the M462RF (315HP) that Iwith it, along with the V530 metal 2 blade prop that is 106" long (2"
landing.than 9 feet!). I am curious about sufficient clearance when wheel
