Hi Bill !!! Wow, the little diesel sounds like a winner !! Let me know how that works out. The teeter head will be a challenge, but I have much experience with them. I hope to have one flying within a month. In the meantime, I will continue having fun with my twin-rotor bird, and hope for the best. Maybe others will undertake this challenge, and share their success stories with us. Two (or more !) heads are better than one, and with more people trying to solve this problem, success should come that much quicker. I believe the key is to use thicker and wider blades, and to use slightly weighted blades and/or a rubber damper of a sort. I remember the old Cricket helicopter, with its teeter head. It used a small thin piece of music wire as a damper for the teeter system. Time to cut-and-try !!! Happy Flying !!! Charlie Anderson
