4 meter scratch build - Glass schedule / reinforcement questions

thenated0g · Jan 3, 2020

Also @Konrad , as i dont have any manufactured fuselages or slope planes, i really want to get a look inside and outside to see how the "professionals" are doing stuff. This will be a pretty cheap way for me to have something on hand to look at.

Ok, the shape will be rather useless as the wing profile will not match or even come close to that of your set of wings. Also you will need to match the F3J wing joiner to your project (fuse to wing interface).

Most "professional" fuselages use what is known as a "Wet Seam". I think you could learn more with a You-Tube search.

I also think if you go to the slopes anyone of us would be happy to show you the details (guts) of our ships. Take a look at some of my posts on the horror that is my RCRCM fuselages. You can also see how Aeroic assembles the fuselage in my Redshift thread. Both threads should save you the cost of shipping for a hollow broom handle.

If you have not found your fuse yet, check out the link https://www.clm-pro.com/store-detail/big-sale/up-to-2m-wingspan-6

They might have what you are looking for. Shipping is from EU.....

We must be in the same facebook groups, i was already looking at that, thanks!

I thought you were looking for a more scale (bulbous) fuselage. If making a glorified broom stick I'd think it would actually be easier to start from scratch rather than piece together a broken one as a mold master.

I'm sorry what are you trying to do with the fuselage?

Got the gifted xplorer fuse in the mail and the wing cores i ordered.

Playing around with some graphics. About 2" of forward sweep. Fuse doesnt perfect match the real thing, but the length and wing location are correct.

Some repairs are obvious but the forward section of the fuse is really strong and needs minimal cosmetic work.

Heres the left wing. 2x 30" and 1x 20" section.

Pretty! Not a big fan of the blue fuselage in your drawing, but the rest looks really good!

lol yeah ill probably mess with colors until the very end.

Nate, unless there is a size limit reason - or something like that, there is no point in having quite so many panels at different angles on your wing as per your drawing - though I suppose it looks quite unique!

I'd worry just a little about the span-wise flow on a flying wing of this type, as the leading edge angles will change its path quite a bit. You never know though - directing the isobars in this way could be beneficial!

Interesting!

Using the re-kitted 'splorer fuse is a great idea!

Doc.

@thenated0g - this will be your biggest adventure to date - I am looking forward to your tail integration!

@bracesport thanks! Already to get to work after a quick trip to Hawaii

Got a slope spot picked out already and a weasel waiting for me
@Doc J This was the compromise we (daniel on rcgroups that cut it for me) came up with. The central 60" section we kept straight so that he could make a perfect tube cut to make my joiner install easier. IE i can glue in a 16mm carbon tube and know they match on each side. Its too late now so what it is, it is lol. I think it will fly fine. I have said it before, im not a picky flyer. All my planes fly different and they are all fun. So as long as it swooshes back and forth across the hill im good

Hey Nate : I'm sure it will swoosh along - in any case, high aspect ratio planken-wings are not that well known for their aerobatic qualities, and in any case with such a sterling advisory team how could it go wrong?

Key point is its on the table, in the flesh, and on the way, and it's no longer an armchair project.

To misquote: Winston "War war was is better than Jaw jaw jaw"

It looks like its coming along nicely.

Keep up the good work - Per aspera ad astra..

Doc in chilly Taiwan.
