Is te RM 150 the same as the electric? I think I have your plans for that. This would be what I was talking about for a TD carrier plane.

Post by: kenneth cook on April 05, 2013, 07:25:45 PM: I found the White Lightning to be problematic. In fact it builds so incredibly tail heavy I don't know how you would balance it using a TD .049. I rubber banded a TD .09 to it and it balances perfectly. The TD .09 is 2x the weight of the TD .049. I sent e-mails to the designer who claims that by no means should I change moments and that I should just add the required nose weight. A sheet wing when designed like the plan shows flexes far too much which totally kills performance. You would find a built up wing to not only be stronger, but it would fly far superior to a sheet wing. I feel that Pat's recent plane that was on paper the Pegasus would give extreme performance. There just isn't many options as many are for reedies. Ken

Post by: RknRusty on May 13, 2013, 11:14:10 AM: My two favorite flyers are a pair of Baby Flite Streaks, one with a Tee Dee .051 and the other with a Big Big .061. I fly them both on 45' lines, the Tee Dee with a 5.25x3 prop and the Big Mig with a 5.5" or 5.75x3 prop. I've been building kits since I was a kid, but with no experts to help me. And when I flew my first Baby Streak, I felt like I was flying my first plane that wasn't a toy.
