I replaced the problematic Super Tigre G.61 2-stroke engine (flamed out on almost every flight - sure got good at dead-sticks!) in my UCD.46 with a new Magnum XL-70 and it runs great. I now have about 8 or 10 flights on the new engine and I'm wondering if I have the best prop for this combination. I'm running a 13 x 6 (the recommended break-in prop). I can hover at about 3/4 throttle. Anyone have any experience with the XL-70 in the .46-size UCD?
