Please help!!!
My wife had the same plane. The last crash was eventually fixed, but in the mean time we bought an Avistar - which is better for a "2nd plane" as it performs areobatics better. But there is nothing wrong with the Superstar.
We fly off a grass field and if the grass gets a little long, we find that the 40LAs don't have enough power to get the planes airborne especially in humid weather. I prefer the 46FX in trainers. As an instructor, I got used to the bigger engines, and when I get a new plane with the smaller one now, I forget that it takes longer to get up to speed and takeoff.
It's a great hobby. Good luck to you.
