RE: Siai Marchetti SF260 ARF
Okay, more work tonight!
After settling on the flap arrangement, I decided to get the fuselage back out and take a look at a troublesome sport for me. The manufacture, didn't fully sheet the fuselage. So took some 3/16 balsa sheeting and cut the pieces out using my planer and some sanding bars to fit the pieces to fill the voids. I'll do the other side tomorrow. This will allow me to round the rear the fuselage out for more scale appearance.
Help Engine Choice. I have a 120 O.S. Pumper, my favorite engine and a New Magnum 91 and my tried tested O.S. 91 Surpass, all four-stokes. It PAINS me to cut a cowling. I will mount engines upside down or any way that will reduce the amount of cowling that has to be butchered.
The manual says this plane will be 9.3 pounds with 698 square inches of wing area. I realize that this plane could way in excess of 10 pounds, with retracts! I don't want rocket ship, but do you think this plane would be a DOG, if I put one of my 91's in the plane? Or should I stick with the 120!
