CF-FZG,
1. After placing the wing on the fuselage, the tubes in the wing slide rather easily in to the stationary tubes in the fuselage. The alignment is perfect because I epoxied the stationary fuselage tubes in to place while the sliding wing tubes were extended. Just a reminder, the wing tubes slide within a stationary tube that is epoxied in the wing. There are no places where carbon fiber tubing is sliding against balsa. I believe that your question is; how do I make sure the wing mount tubes don't slide out during flight. I haven't determined that yet. I want to make that decision at the very end. I want to get the batteries and receiver mounted first, so that I can see how much space I have. I am hoping that I can come up with something simple and reliable. I have some ideas, but it's really a matter of space.
2. The B-52 crash.... I must admit that my information came from someone who told someone who told someone.... Thank you for setting me straight. Perhaps you can answer a question for me. Is the B-52 in this video http://www.youtube.com/watch?v=JlTbAvnTAak the same B-52 that is in the crash video of http://www.youtube.com/watch?v=aRmg88t35Y0 I must admit that I am amazed. That was an astounding plane. I have heard that it was a club build project. If so, then I would assume that they would put only the best of pilots at the sticks. I hadn't even considered pilot error. I can see that it would be easy to get disoriented when flying it on a coudy day.
3. I don't have PatMac's comments in front of me, but I seem to recall that he was promoting 2 large battery packs wired in parallel. At first that didn't seem like a good idea to me, but I was applying my NiCad knowledge to LiPo's. It seemed logical to me that two LiPo packs would not charge identically, so when connecting them in parallel, the pack with a higher voltage would drain off it's excess to the pack that was charged to a lower battery voltage. It's not that I distrusted PatMac's advise, I just needed to take some time and get LiPo battery pack information from a few sources before making a decision. I like the idea of 3 packs, running 2 motors from each pack, but I think it's going to be much easier to install 2 packs. I would be foolish to use one pack per wing because a battery pack loss in flight (for whatever reason) would be catastrophic. The best option seems to be 2 packs in parallel. So PatMac was right. By the way, PatMac really helped me out with the documentation.
4. Thanks for the compliment. I have had some home maintenance to do so the B-36 was ignored for over a week now. I will have an update soon.
