First off I apologize if this question is not appropriate for this forum, I don't know where els to post it.

I have a seagull models superstar. Has a 70" wing, 62" long, weighs 10-12 LBS.

Would a Zenoah G-20ei be ok? Perhaps a 26ei?

Thanks, Pete

G-20 is not going to give you very exciting performance, but it really depends on how you like to fly.
GOOD LUCK
Mike

can I use a saito 125 4 stroke? I dont really need world class performance.

Pete

Saito 125 flies my Seagull Edge 540 pretty well.. I don't know if it is truly "unlimited vertical" but it hauls it up pretty well.. Edge weighs almost 8lbs 11oz.. For tooling around the sky, I'd think it would do fine.. won't pull out of a hover though..

The Seagull Super Star performs very well with a 1.20 two stroke GMS. We have three of them at our club and all are well liked. That would be roughly the same power as a 180 Saito and quite a bit more than the G26. The OS 120AX would be another good choice. Stay away from the gas engines, they are just too heavy for that airplane. The Super Star will weigh 10 pounds with the 1.20 two stroke. When they get heavier than that, they get "tip-stally"

The best advice I can give you is to limit the elevator travel to less than 1/2" each way. More than that and full deflection will give you an instant snap-roll.

Thank you, I a interested in the saito 125 4 stroke just for layed back flying, How will this perform?

Pete

Nice sport plane I would think.

Jim

I have a Brillelli 26 gasser on mine and it is a great flyer.......whatever you choose, keep the speed up and fly the plane down to the landing. It will drop out on you if you don't..........

John ... when increase the wing loading with your Brillelli she will have the tendency to stall for sure! Hehehehe ... A 120 2C would be great for that sort of a plane ... or perhaps a YS110 ...

ok. I take it the saito 125 is ok then?

Pete

YES
