Dick:
Sounds like you are a pretty well rounded pilot that fly's everything. I enjoy the tinkering of this hobby just as much as the flying. I suppose that's what drew me into helis 4 years ago. Started 30 years ago as a kid with planes and got away from it for a while. Well I'm back now and have a good home for my extra $$'s. I don't have a very large fleet accumulated yet, but its slowly growing. I'm not familiar with ACE/TT or even Ripper motors. I'm running Castle stuff, as you know and Align electric motor in my goblin and OS 91 speed nitro in my Rave. I long for Kontronic ESC's and Scorpion motors but they are out of my budget. I don't fly top end equipment but I sure do have fun with what I do have. I'm a little OCD ish about the maintenance and order of my RC stuff!
