I've adopted a CG Super Chipmunk, and I'm learning about the late, great Art Scholl. From what I can find Art learned about aviation with models, and got into full sized aviation with a determination to learn aerobatics. His classic Super Chipmunk is really a different aircraft than the DHC-1 Chipmunk it was based on. Art clipped the wings and enlarged and changed the shape of the tail. He shortened the fuse and made it a one place instead of two, with a custom bubble canopy. He eventually changed to a different engine layout and added retractable landing gear. There were so many changes to the aircraft it was essentially a ground-up redesign. Few would argue Art's place in aerobatic aircraft design history. How did he get there? Did he just whip out his changes on a full size Chippy and go for it?

We know he licensed his design to numerous model manufacturers, such as mine from Carl Goldberg. I came across a video from 1966 where Art was using a model of his Chipmunk in his aviation class. Whats interesting is its apparent the model is flyable based on details like control horns on the control surfaces, and this version of his design was a very early iteration before he changed to a flat 6 engine. So, I was imagining if I were Art. If I had extensive hobby experience and I wanted to design an aerobatic airplane I was going to fly, it makes perfect sense to build a model and wring it out first.

Perhaps I'm out in left field, but we know Art had a very early version (likely) flyable model around 1966, and he later sold design rights (and plans?) to multiple hobby companies. I'm thinking about taking on my CG Chippy, but I may take a closer look and see if I can build a replica of this early version model.

I wanted to post a mini review of the model. I enjoyed the build, my son and I completed it on a rainy sunday in about 4 hours. I've flown it a few times now, and I'm completely comfortable throwing it around. I am a heavy right hand piro flyer, I guess I just watched too much of Curtis Youngblood in my early days to figure out how to go left! The good thing about that though is a push a heli hard in aerobatics pirouetting against torque, and I can find a helis tail limits quicker than others because I go hard left. Going hard right just unloads the heli, so it works a lot harder going left. The Blade Fusion 480 has no problem pulling through when I really ask a lot of it. Big sideways loops transitioning into a hard left piro flip, hard backwards into a hard piro flipping reversal, tight funnels and pulling out with a left piro thrown in, these are the kind of loading maneuvers I do that often find those limits on a machine, where the tail will let go and just give and cry for mercy and flail around. Not the 480, its a well balanced machine, its big enough to have good presense and use standard size servos, but its small enought to be practical on 6s and cost a little less for blades etc. Its fast and aggressive, but stable and planted. Its powerful but still gives me over 5 minutes of flight time (yet to see how much I will get with full pitch range and working into my comfort zone, that may come down)
