Ok, I followed the instructions and mounted an OS .46FX on my OK Models EZ Cap. It took an additional 8 ozs of lead inside the cowl to correct for the recommended CG. Guess what, it barely had enough power to get off the ground.

I've read the RC Mag review on this airplane and took note of the fact that they thought a 45-size engine was not enough -- they used a piped 49.

Well, I found that my MDS 68 crank case was pretty close to the OS FX .46 and weighed in about 8 ozs more so I mounted it. CG was pretty good without any extra weight. I mounted an 11x8 prop and flew it with that configuration for several flights. Nothing to write home about except after about the 6th or 7th flight the wing split in 2, the 2 wings halves stayed with the fuselage until I got it on the ground thanks to the mounting screws and the lip the leading edge fits under -- it was flapping like a bird though. I boxed it up and sent it to the importer and they reluctantly replaced the wing (they took exception to me running a 68 in a 45-size airplane) -- OK Models left out a lot of glue in the wing root area.

I finally got it back together this past week -- after more than 6 months in the shop. The MDS 68 is running pretty good -- 11000 with the 11x8 prop. Unfortunately that configuration does not give this plane much authority in the air -- certainly not even close to trying any 3D maneuvers. I switched out the 11x8 prop for a 12.25x3.75. That didn't improve it much. An attempt at hovering almost succeeded but I was unable to fully control throttle because it required almost full to bring the airplane to a virtical stop. Unlimited virtical -- NOT EVEN!!! This is a 68 size engine in a 45-size airplane.

What am I doing wrong? Did I mentioned that this plane tops out at 7.5lbs? Do I need to go to a 90 to get this airplane to fly as designed?
