After a few months of focused practice and regular sim time, both with an instructor, you'll be ready for the Skybolt. When you can land and take off with NO RESERVATIONS, ON CENTERLINE and with ten miles per hour of wind, then you'll be ready for the Skybolt. Remember, even the ARROW comes alive when the CG is set correctly as determined in flight testing. With my battery and receiver in the foam tray as depicted in the instructions, my ARROW just slightly drops the nose in an inverted 45 degree upline...just barely nose heavy. Perfect for a trainer! This testing was done with an almost EMPTY tank of gas, very important step!
If you had a competent instructor a 4* low wing symmetrical airfoil plane would be a wonderful trainer. Tail dragger planes are a little more tricky to handle on the ground, but not bad. I would still recommend jumping on the buddy box with someone else on their tricycle gear trainer for a few flights, especially when it comes to learning how to land. Many instructors own their own trainer and would have no problem helping you.
Stick with the sim...don't let up!
