I dropped out of the hobby about 10 years ago because the it was no longer a challenge to build and keep a plane in the air. Last Sept. I found the SPA and new life is in me! I currently have a stick with 70 Saito and an Intruder with 91 Magnum and am scratch building a Tiger Tail from Ron Chidgey's plans and cores to be 91 O.S. powered. I love the SPA and wish I had found it years ago. I thought it was boreing to do the same thing over and over again....until I tried it! VERY seldom is my last manuver JUST like the one before it, so I need to do it over and over again! Will be out there every chance I get this summer trying to make the manuvers recognizable!
