RE: 2nd plane
***Sigh*** Here we go again...
What makes a good second plane is a good balance of stabillity and maneuverability, combined with DURABILITY.
Remember, this is the plane you are MOST likely to crash.
Now everyone is different, but the average person should not get anything hotter than a 4*, Tiger II, or the new GP Rapture. And I only recommend these because most people are way too anxious to step up.
IMHO here's what a 2nd plane SHOULD have:
High, Shoulder, or Mid wing with a constant chord, and semi-symmetrical airfoil, that is held on with rubber bands.
Next, it should have a nose wheel. You are still learning, why throw a tail wheel into the mix?
There are a lot of threads here saying "I'm getting a so-and-so for my second plane!". But if you look through the Crash Forum, you'll find a lot of people who crashed their so-and-so because they weren't ready for it.
