I dont have one but a guy in our club does. He flys it with OS.70's and says it flys pretty fast. Would probably be a good idea to let someone with twin experience do the maiden on it. It'll be a handfull if the cg is off too much, an engine starts giving you problems and so on. The snowball effect happens pretty quick with a twin, more so than with a single engine plane. If you could find a hobbico twinstar or something along that line, that would be a way to get into it to see what you're in for. There is a company that makes a TwinAir .45 thats supposed to be pretty good.

I would go that route if I where you. I flew a twinstar for a couple of years while building a P-38. Maiden on mine will be in a few days.
