Unlike every other posting hI purchase the Nexstar on Aug 19, used the flight sim for a week and then joined a club and lined up an instructor. Unlike every other posting here, I have had numerous problems with my engine. The first week I changed all the fuel lines because of air bubble problems. That didn't correct the problem so I enlarged the opening for the fuel tank and completely encased the tank in foam. My instructor removed the limiter on the needle valve so that we could tune the engine more suitably. These adjustments helped, but my instructor has had at least 4 dead sticks in the last month for no apparent reason. I received my wings two weeks ago and have had 20 solo flights but I'm always afraid the engine is going to quit on me. Last night my worst fears came true. I took off made a 90 degree turn and then a second 90 degree turn gaining altitude. When the plane was right in front of me at about 50 foot altitude, the engine just quit. No sputtering, No revving up and down, Just plain quit dead. Needless to say this was my first solo dead stick landing and it was at the worst possible position. I turned as quickly as I could and got it on the ground smoothly, but ran out of runway and the plane hit the barb wire fence post at the end of the runway dead on. Broke the firewall and pushed the engine back into the fuel tank compartment. The plane itself has been a very good flyer. Low passes are flat and level, even at very slow speeds. Landings are smooth and effortless. I took the speed brakes off after the very first flight, and the anti spin wing tips after about 30 flights. I have never used the AFS because I have always had an instructor, and the AFS tends to fight you in every turn. All in all I've been happy with how quickly I was able to learn to fly with this model, but the engine problems have become so frustrating that I am seriously considering buying an O.S. AX. I am grounded now until I get the nose fix. ere, I have had numerous problems with my engine. The first week I changed all the fuel lines because of air bubble problems.
