Congratulations on your Twin-Stik. It brought back wonderful memories. I had one about 20 years ago. At first it has OS.25's on it. Not enough power so I switched to OS.25FSR's that had just come out. It still needed to hit a bump in our field to take-off. I had a lot of problems getting the motors in sync. Wish I had had today's radios. I was the first in the club with a twin and I still have it in the cellar. It needs to be recovered as it was covered with Fabricote, a faliure as a covering. I did get a lot of flights with it. Thanks for the memory. Good luck with yours.
