Try the Ultimate Bipe form great planes I am running it with an OS .46 she handles great, I'm thinking of throwing on the OS 70 surpass II Just for the sound and more power of course, the verticals on the .46 aren't that great but she does fly great with it, very easy to handle after the first flight jitters. this was my second Bipe, the first one was so long ago I can't even remember what it was, I'm still flying this baby today, this is my 3rd season with it.
