I'm finishing up on mine and also put a 91 Surpass in it. I have the original version of this engine. NITB and just didn't have a model to put it in until I purchased the U-Can-Do. Honestly, I was pretty impressed with the model from the get go. Saw one fly at our field and liked the way it flew. I didn’t buy it to do 3-D, but sure I will experiment with it. Here are a few things I realized when assembling that may help.

1. I used an OS aluminum engine mount that fit the pre-drilled holes perfectly. This does put the cowling back further. One thing to note here is that the sky blue covering is not lined up well even with the stock mount. If you use the aluminum mount this will be exaggerated in that this pulls the engine back more than the stock mount. I used sky-blue monocoat to fix this in the picture below.

2. I did use the canopy glue and wish I hadn't. Even though it cures clear, it still shows up with a nasty appearance under the canopy against the dark blue covering. Fixed this with 3M pin-striping tape. If I had mine to do over again I would have placed scabs behind the fuse and installed the canopy before mounting the tank or anything else in the fuse. Do this early if you plan to use screws to mount the canopy.

3. I also fiber glassed the wing in the middle on both sides to add strength.

4. The directions say to mount the battery and the Rx under the wing hold down. I mounted mine forward of the wing saddle behind the tank and balanced right 5 7/8" as suggested in the book. I don't see how the guy in the directions can suggest mounting these under the wing hold down. Maybe I read this wrong, but the picture even shows this.

5. Odds and ends - Put a True Turn spinner on to replace the plastic one. Also used a Sullivan 13 oz tank vs. the stock tank. Used solder clevises on 440 rods with threaded Sullivan threaded clevises on the adjustment ends for all control surfaces. Mounted a remote glow and used Slimline rubber wheels - same size. Hitec 475 servos with a 7 channel Futaba PPM Rx. Mixing the elevators on 2 and 7 and the ailerons on 1 and 6.

I'm ready for the maiden flight hopefully tomorrow if the weather is good. Been cold and windy with rain in the forecast for tomorrow, but will see.
