K-77 prop selection on SV-11 ARF
« on: March 13, 2019, 01:27:14 PM »
Hi Randy,
        I won a K-77 in a raffle last year. I wanted to build something for it but that hasnít happened and not likely to anytime this year. So Iíve decided to buy one of the SV-11 ARFs for it so Iíd have a decent glow plane this season. Iím currently flying the electric SV-11 ARF and very happy with it. I figured you would be the best to tell me what prop to start with on it. Iíd rather not start with real expensive carbon props.

Thanks, Matt

Matt I have one on the Muffler from Kaz and use a Rev Up 13x5 which has 4.5 " Pitch works  well around 8700 rpm 64 ' eyelet to eyelet lines.
Airplane is 62 oz and about 660 square inches. works well.

Hi Matt

For  cheaper props  try a  14 x 5  wood, plastic  or  13.5 x 4.5  , You can trim the 14 inch prop down if it gives you precession problems, trim 1/4 inch at a time.  Hint  you can run a little  larger  wood props  than plastic ones
Those will get you close

Randy
