I flew the original Birdi Kaos and last summer I built the Blue Jay {Bridi} Dirty Birdy to replace it after almost 20 years of service. If anythjing the DB flew better then the Kaos. Second weekend out I had my very first mid air with my nice new DB! I haven't gotten to fly the new ARF DB to compare the kit built to the ARF. I agree with Seamus, the old pattern planes do fly faster then maybe a second plane should. I disagree about the controls being too small. Both of my Bridi's could loop tight enough to kiss there own butts and could roll so fast they looked like they were attached to a drill. Be that as it may. Second plane??Depends on how well you can fly. My second plane was the Up-Roar and my nephew went to the Kaos. The old pattern planes can be slowed down to a crawl for landing but they will never fly as easy as the Pulse.
Do you have anyone at your club that will set up a buddy box for you on there old school pattern plane?? I had my Kaos set up for one and I have my Hots set up now for a buddy box. My Hots has some wild control throws set up in it and it is a 60 size with a YS 1.10 in it. I let a lot of people fly it on the box just to give them an idea of what it is like. If you can fly it then you can fly anything. On the box you can never hurt it either. My 5 yeard old grand son flew it. He didn't scare me but my son did, he does things without telling me first.
Ask around, it isn't hard to set up on the box. See for yourself.
