Ultra Stick 40.. Can it be a trainner?
I dunno. I still feel like people should get and fly what they like.
Problem is, until you've been in the air with a more responsive and better-flying airplane it's hard to know WHAT you actually DO LIKE.
We're having to do the US-60 old-school trainer style (handing over the x-mitter) because the guy I flew with last only has JR gear (oops). Was a BLAST. You can actually SEE the airplane... at distances my trainer becomes a small X in the sky.
To answer the question about your US40 being a trainer... SURE. make sure you have someone buddy-box you at the start...
