So many people have recommended glueing an ice lolly (US = popsicle ;D) stick to reinforce the wing saddle, I want to do it. However, I understand that it is vital to cut back the foam precisely at right angles to the fuselage before fixing the wooden insert - otherwise, the wings won't be straight and the plane won't fly properly (  ) I am not the cleverest of mortals. Please can anyone advise me how to achieve this right angle cut? |

If you are going to cut into the foam for the popsicle stick, then YES, it is vital that you keep it on the right angle, and square. I don't think reinforcing the front with a wooden stick is necessary, only the back. Simple tape will suffice to reinforce the front, the front of the saddle doesn't take nearly as much punishment at the back. I've never cut out a recess for popsicle stick before, other than cutting a little foam out of the corner at the bottom so the stick can sit flush, and I've never had any problems. The wing sitting 2mm further forwards isn't going to make much difference at all, the saddle is at least 3mm bigger than the wing. As long as the wing sits snugly into the saddle it will be fine, I don't think you should risk cutting into the foam if you don't have to - you might end up like Skivit. supercubclub.proboards.com/index.cgi?action=gotopost&board=ts&thread=3155&post=21586 |

Yes,trying to avoid being like me is a good idea.  Funny Dill I thought the same thing when I read this post.  |

Very many thanks for the advice.
I thought it would mean cutting back the foam at the rear of the saddle. Now I know better, and can go ahead with confidence.
Some of you experienced people may not appreciate how invaluable we newbies find this forum! It is just great how helpful everyone is.
Thanks again.

You are so right on that renard. This place is a big help.

Sorry for the misinformed advice I like you too am learning. I just did and posted what made sense to me.
Once again sorry for the poor advice.
John

Actually John, I thought your mod turned out pretty well. It's just risky, somewhat difficult, and not really necessary.

@ Dillzio
Hi so after reading up a few here in the Thread I read that you don't trim away the Foam you just Epoxy the Sticks on...? What about the Space or lift on the rear of the Wing.? So I guess thats not a Problem because it seams to not be that much of a Gap but I don't know & that's why I am here.?
Thanks

@ Dillzio Hi so after reading up a few here in the Thread I read that you don't trim away the Foam you just Epoxy the Sticks on...? What about the Space or lift on the rear of the Wing.? Thanks Are you thinking that the Popsicle stick goes under the wing? It goes on the part of the fuselage that holds the wing from going backward. So it moves the wing forward a tiny bit. That won't hurt anything. as it is such a small amount. The SC is such a floater and has so much lift to spare, that making little changes will be nearly imperceptible in flight. Remember, some are putting digital cameras into their cubs and flying them to 1000 feet. I found that while I was adding the wood to the fuselage to reinforce it, that the back of the wing was now the weakest link, and so I added a thin piece of airplane plywood to the bottom of the wing, glued even with the back of the wing, and slipped underneath the plastic piece on the back of the wing. This has kept my wing from cracking along the back edge after several cartwheel type landings. Here's a link to my thread, with pics: supercubclub.proboards.com/index.cgi?action=display&board=sccgeneral&thread=3439&page=1 |

Please can anyone advise me how to achieve this right angle cut? Let's clarify some misconceptions that a lot of new Super Cub owners may have. The Super Cub is a very stable trainer and is very forgiving. Even if your CG is a few millimeters forward or aft it will fly just fine. You used the word VITAL and PRECISELY when talking about the wing saddle mod. I have never found anything about the Super Cub to be vital or precise. It is nice to try and achieve these goals when doing mods because you learn how to do things that later on another model MAY be vital and need presision but believe me when I say that if your wing it not perfectly straight in the saddle you WILL NOT BE ABLE TO TELL THE DIFFERENCE IN FLIGHT. Don't go crazy unless you are a perfectionist and enjoy that level of perfection. Cut the foam lay the stick in as it shows on the video, place the plane on the floor and put the wing on the plane. Stand back and look at the plane from the front and the back. If it looks good, glue the piece in. No measuring needed. Ifly |

while we're talking about wing saddles, what about the tail wing mount? i just cartwheeled mine on takeoff (better than getting hit by a car on takeoff roll), and i found the two holes that go through the back of the plane that hold the whole tail assembly in place damaged, so my whole tail could move a half an inch in either direction (i took off after wards, and i was wondering why it was flying funny)what i did was cut a chunk of lexan ahd hot glued it to the flat spot where the tail wing meets the fucelage, after cutting away the thickness of the lexan. i don't know how it'll work, but i hope it helps some.
