A 50 something is a great way to go, fewer troubles with tuning or heat, plenty of power for aerobatics, so it won't get outgrown. The only one i have flown is the raptor, liked it so much i have two now, but i doubt the brand matters much, the Scedeu and voyager are also popular choices available in a 50 size. Check with your local shops, having spare parts available localy really is nice.
