Re: Saito 91 issue

A 14x6 @ 10,500 is quite good. My Saito .91 would turn an APC 14x6 @

11,000 on a good day when new.

The Saito .91 can hang around 8.5 lbs on the prop.

At 11 lbs the .91 is probably starting to strain. You can play with different prop sizes but its maybe as good as its going to get.

I believe the SE5A is a bi-plane. Bi-planes have a lot drag and its 11 lbs. You may have to make a sacrifice somewhere.

I have a Fun Aero SE5A with a Saito 91. I bought this engine from another >club member who couldn't make it run. I fixed the air leak, runs great, but >now I have another problem. It turns a 14X6 Master Air Screw prop right at >10,500 RPM on the ground. I am chalking this up to the size of the cowl and >am wondering what would be the correct prop to try. Plane came out a little >heavy, 11 lbs., and could use a little more thrust. >Thanks >Bill >

ROFLOL!!!

Real "scale" manuever!

10.5 is not bad, mine just barely broke 11 on that prop when new out of the box. If you want more thrust, try a 15X5

Nothing like horsepower. When you just can't flog anymore power out of the 91, look to a Satio 100. Even a 120 if you had to add nose weight, you could change the lead for working horsepower. good Luck, Andy
