I have a wing b-25 with saito 80,s. It has been taxied but not yet flown. I have been flying 18 years and fly low and high wing and
bipes. Do you think I will have trouble with this as my first twin?

Anyone out there have one? any comments welcome

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.

Unless you have had experience with high wing loading models (30 oz per sq in of wing or more) I would strongly suggest getting some assistance and advice from someone who has. The flying and landing technique for this type of model is different than what you may be used to.
