I'm going to try and fly my Twist with a Saito .56. Had the engine sitting around, and got tired of listening to how much better said airplane would fly with a 4 stroke. I know that .56 will prop hang a 40 Rascal very nicely, so I'm guessing it's going to be more than a match for the Twist. It turned a 12x6 at better than 10 grand, so a 13x4 APC, one of the broad bladed 3D props, is mounted. I also have a 12.25x3.75 if that turns out to be too much.

I know I saw a post where someone else mentioned they were mounting a .56, if so, and if you're still around, how did it fly? I don't expect to rocket off from hovers, but I'm not quite up to hovering reliably yet, so it's not an issue.


TIA,

.56 mounted on Twist, was just about the easiest swap I've ever done. Throttle linkage wasn't even an issue, just had to turn the carb around. Engine is pulling 9600 rpm with an APC 13x4, and about 10,900 with a 12.25x3.75. Will try and fly with both, hopefully tomorrow, and will drop flight report when I get it. I really like the throttle response already... but we'll see when it gets in the air.

I had a TT .54 FS in mine and changed to an OS 70 because I could not get it to go. I hope you have better results with your Saito 56! I also found that it needed a lot of nose weight in otder to obtain good balance.

Well, the .56 was just right. Unlimited vertical, couldn't really say where it hovered at because the wind was blowing a bit harder than I can hover in, not that I can hover all that well when it's calm. But it was more than enough power, and the 12.25 prop was perfect. I've only got one ounce in the nose now, and it's flying perfectly. Coulnd't think of a better engine/airframe match.
