According to the links I posted, that is no longer true.

Interesting, I'll have to experiment with that. I did a test earlier this year (in August, I didn't check the temperature in my workshop but it was probably in the mid sixties or low seventies). Putting a coupler into a piece of BT-60, a thin film of Glue-All grabbed immediately. A heavy application (2 or 3 times as much) stayed mobile for a minute or two. Both thin and thick applications of Elmer's Wood Glue (yellow glue) grabbed immediately. Of course a comprehensive test would involve many trials of several different glue amounts. But this showed that Glue-All (at that temperature) can grab right away, and without a lot more experimentation I'd be uncertain how much I'd have to use to avoid grabbing. Certainly the thick application I used was what I'd consider excessive for good building technique.

I have two broken skywinders and was wondering if you fixed yours. |

I would be interested in buying the two broken skywinders off of you If you are interested in selling them. I had one when I was a kid and one blade some off and hit the ground and cows ran over it so I have been looking for one to buy. Thanks for your time Jordanlammers@yahoo.com |

I’m sorry but already bought the nesting tubes to repair them and they are high on my list. I’m really attached to them, one has 37 flights and the one with the D mod has 6. The one with 37 flights has short rotors because of a non eject so the rotor tips are missing(central tube was shortened in first repair). I hope you can find one. |

Did anyone confirm which tube ended up working the best? Getting back into my remaining rockets that were left over from our house fire back in 2011. Lost most of my collection at that time but the skywinder was one that survived but the tube below the nose cone is bent badly. The virus has motivated me to finally try to get back into the hobby and I figured might as well start with the broken ones.

I haven’t repaired my 24mm conversion yet which was outside for 6months. I went to repair my original skywinder that was outside for one month because the fincan seperated from the tube and I couldn’t find it. When I found it the tube and was wet and curved a bit. When I looked at last year before repairing it, I discovered the tube dried with only a little staining and lifting in the outer wrap and had straightened out. So the repair just required gluing the tube back on the coupler that’s above the fincan. The bad news is on the 41st flight and fourth launch after the repair, the plastic slide that joins the nosecone to the tube that takes the brunt of the ejection charge and vents the charge, sheared through the three legs, one that was previously reinforced with a piece of styrene, you can see in the pictures. If anyone has an idea about how to repair this damage let me know.
I’ll prioritize repairing the other Skywinder with the tt20+ and bt20 nested and let you know how it goes. |

I got the two Skywinders out to check on what needed to be repaired. I knew that Estes made improvements for durability after the initial release and looking at both models those changes were clear, specially since the slide on the original version sheared off. The changes I see are:
1) The slide/exhaust vent plastic is around 2.5 times thicker in the second release. I don’t think it would ever burn through and shear off like the first version did. On my original version, one of the retaining ‘fingers’ cracked and I reinforced it with styrene, but the whole thing sheared off after 46 flights. 2) A paper retaining ring was added to keep the three ‘fingers’ that retain the slide on the tube from separating. This happened to me, causing the nosecone to seperate, and I added a retaining ring even before the kit revisions were made. 3) A paper insulator was added above the motor. The ejection charge would melt and crack the plastic tube/rotor part since it was not protected. This happened to me on the first version and I glued the part back together with JB weld and added an insulator. 4) the plastic tube/rotar part was given four strengthening ribs. This was to prevent the cracking seen in conjunction to number 3. I can’t think of any Estes kit so extensively modified in a second release to improve it.
