Why reinventing the wheel? We have build many Correx creations using hot glue and contact glue only and never had any issues with glued joints coming apart.

Sorry about the S-flute correx Billy....you can build with it....but leave it till later when you have plenty experience with it!
What it does is, at the end....the planes lines are not as neat. You need to cut V's with a soldering iron to bend it properly.

But the straight flute.....well.....it was designed for us glider builders

UHU Por

Hi Rhys
I have used UHU Por on the spar and on the trailing edge/ailerons.
I had issues with the trailing edge gapeing open in places. Possible that it was not under pressure long enough or had gone past the tacky point. Not sure.
One thing though, UHU Por is expensive stuff, I now get tubes of contact glue from the 1 shop and save the Por for foam only. Ten tubes of cheapy CA super glue for a quid as well. Just as good as the expensive stuff for what we do. Only problem with that is as it is cheap, I tend to spash it all over and end up with skin stuck all over the place.
I have also used spray on carpet glue.
Regards
Simon

Thanks Simon, what 1 shop is this and what would be the name (if any) of the contact glue you get? Lke you said, need to get something cheaper than Por for general use.

Yes I have tried it...was not very successfull.....but that does not mean it does'nt work...maybe it was my process that flawed the joint...did flame the surface though.
However, CA is not flexable.....correx is ...IMHO.

Never seen it here in ZA!....
Must be good though...when you do a Google Image search, just that and model airplanes come up!

But yes!...I recon it will work......again, if you get your process right....close when tacky and clamp for at least 30 min!

Not sure what the shop is called, don't they all sell the same stuff?
I must admit, it smells the same as all the rest, just like Evo Stick, possibly more so. I get the same head ache after 30 minutes anyway.

Hi, TRex99, always good to see someone else enjoy the Mig.

I've always used the ca. Some days work better than others. After looking into it, it seems the temprature makes a lot of difference. A slightly mild to warm day it works great. If it's very cool out, trouble. Preheat the material if you need to ca when it's cool.

About the Goop. other similar products would be, Shoe Goo, might find it at a shoe shop.

or E-6000 found in hardware and craft stores
http://www.eclecticproducts.com/e6000_series_retail.htm

Good luck with those. You make us feel spoiled when we hear you can't get stuff there. But when you guys get together on those SA slopes, well lets just say, it's a long drive from here.

Once I discovered the wonders of hot glue, I was sold! I still use the goop stuff when I need a good bond, like with firewall doublers, (Combat!)

CHeers for the input guy, I'll give the UHU por a little go on the wing and aileron I think. I'll have a look out for the cheap stuff too, thanks Simon

So some good progress this weekend (yesterday) after having a few hours off from the other half
Managed to get the Fuselage sorted up to the point of doing the nose. Had some slight bother with formers F2 and F6, F2 didn't seem to fit at all (see picture) so was a slight fiddle to to get right. I ended up glueing one in and then ripping it out as the Fus was as crooked as a crooked thing. F6 was just too small too work with for my liking! I squashed the bottom piece so had to reinforce it.
I started with F5 as that was the easiest and worked forward, not sure if this was the way to do it but it turned out good and am pleased with the result.

After glueing F5 and F3 (skipped F4 to get the correct shape of the fuse before gluing) my Glue Gun snapped a trigger.. Oh ****! See the pictures for my bodge job

So all formers are glued and the fus is as straight as I could get it, it's not perfect (far from it actually) but for my first attempt I think it will do I fitted the tail just to check and it is slightly off, I can glue this in straight when the time comes.

Enjoy the pictures, hopefully I'll get the tail started later today and start a wing

Looks nice, I should have cut the bulkheads from coroplast too, the plywood I used was very time consuming.

Keep up the good work!

Hi Guys,

First of all let me say, its the only coroplast PLAN that I found on Rc Groups, (if u know anyother please post a link or PM) and its equally beautifull. I am planning to build one, I am new in scratch building (not very new) I build my 2nd F-22 with 3 mm coro.

I am planning to build this beauty with 3 mm for fuse and 2 mm for wings. Got few questions and will appreciate if u guys can take out some time to answer the followings:

1. I am planing to build electric one, the size of original (44.8 inch wingspan) looks big for electric? if yes then can I get some plans for smaller size.
2. what modification do I need to make in Fuse Formers to achive electric outrunner fit?
3. Fuse Formers can be made from Coro (with some extra strength added)?
4. Last but not the least, if any one is flying electric MIG, can u please tell me what power setup is best for it?

Thanks for all your time, looking forward to start the build in few days (after gathering required info) Once more great plane.
