I solo'd after 4 flights on buddy cord. I have an Arrow. But, I have been flying electrics (flying wings, war birds, sailplanes etc.) for 3 years too. The Arrow doesn't have much dihedral (wing in a vee type shape when you look at it from the front). It also is a semi symetrical wing. Therefore, it doesn't really have the "plane will right itself after a turn". You have to straighten the aircraft yourself.
And you'll drop altitude quickly in sharp turns if you don't give it a little "up" on the elevator. I also think you have to respect the power of these planes. They sure don't fly like any slow stick!!! I'd say the hardest part for me and I'm still learning on how to be smooth is landings. Just when you think your on a nice graceful glide for landing, a small wind gust pops up!!! And getting lined up for a good landing. When you start getting cocky, thats when you will crash. Ask me how I know this firsthand when flying electric!!
