Here's a YAK that should hover with it. Couldn't ask for better control surfaces.

They also sell a CAP and Extra that will work. If thery're out of stock try here.

Your .46 will hover this CAP. It builds lighter then they say. I had one with a YS .63 in it and it was insane. Can't help you with kits but RCKen sure can if you want to contact him.
