I really like the superstar ep but I have to admit I knew how to fly long before I got my superstar ep It's a good size plane and takes a lot of room to fly unlike the aerobird. it'd be a better second plane Randy
kihei11 and Aeair:
The problem is, I can't get the plane off the ground. As soon as the plane gets close to takeoff speed, it ground loops. Into the wind, with the wind, cross wind, no wind, before I can take off, the plane spins around.
I put the plane together exactly as per the instructions. The Center of Gravity is at or a 1/8 inch forward of maximum but, while in the extreme, that could make the plane more stable, less responsive and a bit reluctant to rise off ground it should have nothing to do with the plane ground looping.
I've tried to stop the loop with rudder but it just loops faster in the other direction. I have no trouble on takeoffs in the simulator that require a bit or rudder.
I've tried a quick glance at my aircraft design books regarding lateral stability and the solution seems like it might be a larger vertical stabilizer. But that was a really quick look. Have you ever heard of this? Any suggestions? Unless I'm really mistaken, there's something seriously wrong with this plane. But I think it should be easily fixed.
Thanks.
First line above: You are talking about a real plane, not a simulator plane, right?
Are we takling the EP Superstar Electric - 3 Channel?
1/8 inch forward of the maximum what? Max forward CG? Max rear CG? What Maximum?
Ground loop - Aee you flipping over backwards? Nosing over and tunbling forward? Left side? Right Side? Always the same? You say spinning around, but I am not 100% sure what you are describing.
Do you have a steerable wheel?
Are you trying to take off from a hard runway? Gravel? Grass? Long or short Grass?
Have you EVER successfully gotten off the runway? Has anyone?
Are you working alone? With an instructor? A coach? What are they suggesting?
