Hi There,
I have the Balsanova 120 are and the kit. The arf is easy and pretty straight forward to assemble. Not uncommon, but had to re shrink the covering. It was kinda wrinkled. I built new tail control surfaces for it and added 3 inched behind the hinge line. I called Morris and asked them it any mods had been tested for 3D flight with this bird. The extra 3!QUOT! was their suggestion. I, like you, am using the saito 1.50 on the plane. Great engine as you would expect from Saito. It really flys the Balsanova well. Watch your tank position. I had the Saito inverted initially. I could not get the tank low enough to stop the siphoning of fuel. This is easily cured with a regulator and/or pump set-up. I opted to mount the engine horizontal instead. Then it worked well. The throttle linkage was a challenge, but I took my time and ended up fabricating a pivot bar set up for the linkage. I used ball link and carbon fiber for all linkages and Aluminum Control arms from SWB through out.
It flys very well. I haven't done any 3D with the plane yet cause the engine is not completely broken in yet and has not settled down with the adjustments yet.

Just a note on the Saito 1.50. I had to try several props until I found the right one for the plane. The 18!QUOT! are TOO big for this engine contrary to what the manual says. I know that the engine is not 100% yet, but it is just too much prop. The 16-6 in Zinger Pro, or the 16 X 6-10 from APC seem to pull the best for me.

I hope to have the engine fully run in this winter and completely ready for spring flying. This is my first large aircraft, and was nervous setting it up and flying it this summer, so it did not get the running and flight time it should have. Now, after some help and patience from a great club member, I got over the !QUOT! really cant think of crashing this plane nervous nellies!QUOT! I have a very nice looking and flying plane. I hope to start doing some 3D action with it this coming flying season

Hope you like yours as well
