Hi. I have just pulled a Ryobi from a trimmer. It saw a couple of light seasons on it. I removed all the excess off of it including mag. I intend to use XYZ EI from hobbycity. Also replacing the Zama carb with a 12 mm Walbro. The cylinder bore is very clean, no scratches or ridges.
I have cut all the excess from the back cover.
Starting to draw up plans for biplane that will be just a little bigger than my Kadet Senior. 80 inch top wing 70 inch bottom 13 inch chord, for 1950 square inches. I am will be using boost tabs http://www.rcuniverse.com/forum/tm.asp?m=375915 to cut weight i.e. normal servos (48 ounce inch) and 1000 ma battery. That will cut a about pound versus using 1/5 scale size.
My question is does anyone have a drawing of a mount plate they could share. I have some quarter inch aluminum plate I will cut mine from. My plan is to use aluminum stand offs drilled and tapped for quarter twenty bolts to mount to the firewall with.
