All went well in building. Be sure to glue magnets in place for top canopy. I would use a different means of attaching the ailerons , rudder & elevator to the planes brackets. The nut that holds the mounting arm comes loose. I would at least drop some Epoxy on the nut and threads so this don't happen. I used a 4 cell 4400 ma battery, I had to cut alittle on the foam to make fit and set plane up like instructions said. It took off from grass run way without any problem. First flight I thought went very well . No bad tendencies . I actually loved flying it. Landing you have to remember where your throttle is at, I never had a problem but, I watch for stalls and keep power on until you get close then land. I would recommend this plane for aerobatic and 3d and just plane pattern flying. It did everything I ask and then some. You should be happy with your purchase of one of these Bach 342 I am. Hoping for a lot more flights.
