I am running the Saito 72 in the twist but I have a Magnum .91 in another slightly larger but similar plane (Funtana 40S). I think the Magnum 91 may be a bit heavy for the Twist. The power would be OK but you will not need that much. The 70 size Saito pulls the twist up verticle faster than the 91 Magnum does on my Funtana, which is a little bigger and a little heavier. I would go with the Saito .72 or .82 or the Magnum 70. The Magnum versus Saito debate seems to be the Ford versus Chevy debate. I like them both, I find that my Saito is easier to adjust the needle valve for the appropriate high end speed and it cranks a little easier. My Magnum on the other hand idles better...? All good choices, try the 14X4W prop, or if you want a little more bite and a little less breaking spead, go with the 14X6. Put some 2.75 or 3 inch wheels on it for clearance and better grass landing. The twist is a great little plane.
