Stick to Polyurethane, such as the previously mentioned Sika PU glue, as it expands into the foam core and forms a very tight bond. Not much is needed either - just a thin layer.

Are you going with the wing as shown on the plan?

Don't know if you have the original magazine article(I've got it around here somewhere), but I seem to remember that the author mentions that increasing the wing area by 10% over that shown on the plan would be a good idea.

Yeah, have already had cores cut, but may be able to increase the span a little but not much more than that unfortunately. I have the magazine in a box somewhere, might find it one day. May just build as per the plans and later on get a new set of cores cut with a slightly larger area.

Yeah, I might have a look at it tomorrow. Good thing is I know how much another set of cores will cost and I know I have the balsa to skin them.

Got to say Steve, have been enjoying watching your Boomer' come along. My late Grandfather was a flight test engineer on the Boomerang, CA-15 and Woomera before moving over to GAF after the war. I'll give you a guess at what he designed there. Always enjoy seeing models of the local hardware being built.

Hi Guys,

Just a quick update tonight.

Started shaping the engine pods, one side almost done, one side still to start.

Still thinking about the wings, whether to extend the span or not.

Decisions, decisions.

I have the same planes from Phil and it looks great. I ended up building a hybrid from those and another set of plans as mine is a pusher F-111. One day I will build a EDF with the two 68mm ones I recently purchased.

Your fuse looks terrific so can't wait to see the final product.

Thanks Shane,

Humidity has been a problem here this week and to top it off on Thursday we had some heavy rain which came into the garage. Fortunately nothing for the model got wet, but I have had to move some stuff around which is making it harder to work on the plane at the moment.

I would love to build a powered model of the Pig, swing wings and all, but after shaping this fuselage so far I don't know if I could put myself through that again. Might wait to see if the rumors of a EDF foamy come true.

Hi Jindivik,

Your Pig is looking excellent.

As Steve said I built one from Phil's plans at 150% of the original size.

Stupidly sold it and have been trying to get her back.

I extended the wings to the profile of an F111C. I would suggest doing the same but also increasing the chord a little. Every bit of area helps.

F111C:


F111, the rest:


Note how the C model wing tips reach the horizontal stabilser tips when fully swept.

Hi Glenn,

Was going to send you a PM and then you appear here

I found a couple of photos of your Pig on here and it was those photos that reminded me of the plans.

I am thinking I might extend the span a bit to more resemble a C as I am planning on painting it as A8-132 in the ARDU colours. I dont know if there is much I can do with the chord with the cores though, but as I said earlier, I can always get another set cut in the future and have a couple of wing sets.

I was going to ask you Glenn, how did you tackle the tailplanes? Did you stick to the plans or did you use a different method? I was going to use carbon fibre tube to join them and some brass tube through the balsa sides and foam engine nacelles as a bearing.

I would really appreciate any tips you could give me for this plane Glenn. Have been really enjoying getting back into building, looking forward to being able to take it for a TFR run along a slope.

Would you consider building another one, or do you want the old one back for sentimental reasons?

Chris

Actually the G's had the extended wings as well. But they did at various times experiment with using shorter wings on the C's due to the fuselage stress issues prominent in there later years. They were very strictly G limited and any over G (around +4 from memory) required extensive inspections before any further flights. It was shown that the use of shorter wings transferred less stress through to the fuselage wing carry through box, and instead just stressed the wings of which plenty of the shorter varients could be sourced easily. So it wasn't unheard of to see a C getting around with shorter wings fitted.
