OS .52 4-stroker prop
 

Have a .52 OS 4-stroker on my seagull spacewalker II. Was thinking of running a 12x6 prop.
Does this fall in the suggested prop range for the engine? I run a 12x6 on pete 'n poke (saito .56 4-stroke). I run Morgan cool power 15% nitro on these engines.

Lucky...

I run a 12x6 prop on my Slow Poke with an OS 56 on it. it's a nice setup for that plane. You'll have no problems with at all.

On my LT-40 I am running a 12x5 MAS K series and 10% with no problems. You should be fine unless the landings are a tad hot. Then go down to a 12x5.

My favorite prop on the O.S. 52 for stroke is the APC 12.1/4 x 3 3/4 prop. it pulls like a tractor, and when you cut the throttle, it's like stepping on the brakes. Speedy it isn't, but then you are running a 4 stroke.

When I was first starting out. there was a guy on Ebay selling Zinter 12x6 wood props. Something like $0.50 each in dozon lots. I burnt my way through the first dozen then I tried the 12 1/4 x 3 3/4 and never went back.

I used to have a trainer with a Magnum .52 4-stroke and I ran a MAS 12x6. Worked great.
