Finished up this nice little model recently.  I do have a question though........how do I keep the nose block assembly on the plane after the rubber has lost its tension?  Even though I built a nice snug fit, with the weight of the prop etc. as soon as tension is gone, it wants to fall off the front.  The frame work around the front is only 1/16" thick by 1/8" wide so I can't really use any magnets etc.  Just curious as to what some of you guys typically do.

Thanks.

You can use a pin to hold it in place, but most guys use a rubber band and some anchor pins or hooks to hold the block in place.

You can also use some tiny neodymium magnets in many cases.

Magnets can be very nice. However, there are other ways.

For instance, I think it helps if you make the part of the plug that's inserted into the plane out of cork. (Real cork, as in from a wine bottle, and not that plastic stuff either.) You can make it a bit snug, and it has reasonably high friction.

For more on plugs, go to this page:
http://www.flyingacesclub.com/FACAbout.html
Download the index for the newsletter, search for "nose plug" and download the pertinent issue. There's a lot of good info. If you prefer Excel files to pdf for the index, you can download it with the first link in the first post of this thread on RC Groups:

If that's out of date, you could go to the FF forum in the Exotic and Special interest section and search for a thread with the word index in the title:
https://www.rcgroups.com/forums/search.php?f=64

Lots and lots of other useful info there, although of course there's a light admixture of claptrap to keep it interesting. Plus fiction, model designs, etc. Some of the fiction is claptrap at the same time, though people's opinion of Phineas and Archie Whitehouse stuff may vary. And you may find the work of illustrations and stories by  Stott and Rogers in this category too, though I usually prefer it. One of my favorites is the Westland Whynotte, both the picture and the story. Someone needs to build one. Some of the Glue Guru's stories are pretty funny too, particularly the one about the duration contest held from the Eiffel Tower. But they usually end up with somewhat more serious meditations on the art of stick and tissue flying scale models.
