Re: SIG

I thought the same thing when I seen it.......looks like they altered my 4foursixty to accept a plug in wing. Is there any way to convert this to bolts BEFORE you use elastics? I've done this on a lot of planes and would suggest it to SIG in the letter.........granted you guys are doing 3D away from people I would assume...........but it can also be a safety issue. I was thinkin of getting one of those or a UCANDO3D. By the way.........in the second picture........I thawt I thaw a puddy-cat!! Good luck!!!

It could be done with a blind nut type setup but the wing rib would require some major reinforcement to be able to hold it.
I think a much easier way would be to have a MUCH longer rear dowel that extends into the wing so when the wing does pull away from the fuse, the rear is still going to be supported by that dowel. You still have to deal with the elastic problem but this is one solution. Using two/three/whatever elastics is not that great an idea. The lateral force exerted by the bands on the hooks might just pull em out. That's why I didn't use the zip tie suggestion. I had reinforced the hooks with additional ply on the inside of the rib where they screw into but man, those threads on the hooks are pretty darn small. The hooks survived the crash (no lateral force at that point) but the wing/wing tube moved a couple of inches forward. Changed the CG on me, drat it all. Instead of trying to rebuild the front of the fuse, I'm thinking I might try to stick these wings on a fazer that went in a while ago. The Fazer has a one piece wing that just slides into the profile fuse (fazer is just the profile version of this extra). Maybe fill the hole in the fazer fuse with balsa/ply and figure out some way to mount the throttle servo and receiver/battery. In the fazer, that stuff is inside the wing. Longer rear dowel is an possible response to a poor design. |

I agree that the J hook and rubber band thing has always been iffy and there have been many references over the past few years in discussion groups about the SE and how to improve on this wing fastening methodology. My SE has over 190 flights on it now - I have always tripled the #64 rubber band (ie fold over 3 times) and I also always turn the J hooks so they face 'up' after I put the rubber band on them. With the way the slot is cut in the fuselage sides to allow the J hooks slide through, once they are turned up there is no way the wing could slide more that about 1/4 inch and would still stay on the rear dowel.

Was talking with Jollydude about this thread. We both have SE's, and neither has had this problem. He has a lot of flights on his, and believe me they have not been put-put around the sky like a trainer ones. Of course he also left the wing dowls longer than the plans call for.
He also uses 2 #64s, installing them as follows: hooks 1 end of band on hook 1, runs band to hook 2 (with both parts going around hook), then hooks 2nd end around hook 1. Then does same with second band. Wade

It was bound to happen, but considering all the hundreds of SE's out there, most have survived with the stock setup. The only time that I saw a problem was a friend who forgot to install the rubber band. Fortunately, the wing freefloated, and he was able to bring it in for a safe landing.
I had 1/4 nylon bolts securing my wings to the fuselage. It was a real pain getting the wings on and off, though......

Never any trouble with mine.Once I wrap the same one on there twice each hook gets twisted in the opposite direction.I have only replaced the band a few times but in some cases I have flown dozens of flights before the wings get a new band.I have now had this plane for three years and I still love to tear up the sky with it.

sorry i lost it back there.....lol......was having a bad day and it seemed like a good time to blow off some steam.....
i do agree that SIG should be trying to fix this for the later kits, but that is an accident that could happen to anyone, anytime......on almost any plane even..... i could have lost the funtana the other day if i hadn't changed the nylon bolt that was holding the wing in because it was all stripped at the top..... |

I apologize for the use of the term "crappy design" in my first post. I should have used the term "in my opinion it is a poor design". It was written on the day the plane went in and obviously I should have waited till I had recovered from my disappointment and upon reflection, chosen my words more carefully.
I should also add that SIG has contacted me regarding this incident (my crash, not my post although reference was made to it in an email reply to me) and I offer the above freely and of my own will. I have learned a valuable lesson from this: get your head on straight after adversity and you won't say things you'd like to get back. This goes for all things in life, not just this one. What I said could (and should) have been phrased differently. And that is what I apologized for. |
