This is turning into one of the most informative tutorial threads that I have seen on this forum! And the information just keeps coming - This is excellent! Shufflez, that was a very good analogy that you used - the bicycle wheel / rpm / wobble. You handle the 'foreign language' better than a lot of us who have English as a first / only language. I knew that there was a reason why the higher head speed was more stable, but I wasn't certain why. As a kid I used to play with gyroscopes, and there was no doubt that it was more fun for the first 15 seconds of run-time than the last 15 seconds when the speed was way down. You mentioned hotter batteries and gearing. I assume you are looking for more head speed. Remember this is a fixed pitch heli, so head speed = altitude gain. Racin06 shows some really good footage of his fixed pitch working really well. I expect that he would see improvement even beyond what he is demonstrating with more head speed. I am truely impressed by the demonstration that racin06 shows. It has become obvious that I don't need a cp heli. But I sure want one. At the next flight I will have the antenna fully extended. I demonstrate a really bad attitude when I loose concentration from nearly flying into my own antenna. I'll deal with that. And I am going to dress my heli antenna differently to keep it out of harm's way and not wrapped around the tail stay with the metal rod in it. cx2cp+ - I have reset my paddles to neutral. I don't need any more rotor drag than I have now. And I'm all about stability. For the record, I don't expect the single rotor to ever fly like a coaxial. In fact I don't want it to fly like a coaxia - I enjoy the challenge. The purpose of this post was to learn the setup details and to help me decide whether I wanted to fine tune the fixed pitch or just get a collective pitch. I was so far from the control that I expected of a fixed pitch that I needed to know if my problem was setup or just pilot error. It seems that I did a good job of setting the parameters that I was aware of - but I was only half done with the job. I don't know if it flies better yet, but it is more technically correct. That should be an improvement as I get more stick time. Looking at your photo, looking from behind as we are, your flybar is 90° to your rotor drive shaft and the blades are parallel with your flybar. I had an exchange with stump3r and both of us have level flybar but the rotor is a few degrees right of horizontal. That seems wrong to me, but I have no idea what to do about it. I'll look at the paddles again. I may have one off level just a triffle. ALL - I have learned an encyclopedia's worth of great information through this thread. Because of all that I have learned through this thread, I'm not ready to give up on the fixed pitch yet. Had I gone to the collective pitch as Shufflez did I would probably have not only frustration, I would be in debtors prison. I have learned from racin06 that I am way too concerned about the super skid's added weight. A little additional weight adds head speed. Perhaps shortening the rotor by 10mm ( 1/2" would also increase head speed. And a faster motor may help some too. I'm back to experimenting / learning again but this time I am well armed with information. Thanks to all, Soloboss
