Well, that was some challenge, read the entire thread from start to finish, NOT in one session, not even close, 4515 messages!

Now, to decide which one to build, and the size. Tempted by a big one, but there are practicalities to think of.

This is going slightly off foam, but has anyone used corrieboard for anything like this? Best way I can describe it is that it's the plastic cardboard replacement that's used all over for things like estate agent signs, and it comes from 2mm up to 10mm. I have a supplier locally, and am heading up to them to get some samples later, so I can do some testing to see what the weights are like, and the stiffness. They might also do some foam, will see what I can find out.

Was looking at some of the contra rotating props that HK do, anyone used any of them?

Did anyone get their 250% size in the air yet?

Seriously impressed with both the variety of Twins that have been flown as well as the Quad tilt rotor in the related thread, very thought provoking indeed.

Kudos to all concerned.

On this side of the Pacific we can get Coroplast board from RCFOAM.com so

Go a head and lead the pack by doing your version in coriboard with a build report.

Bob and others , I was surprised to see 1/4" ( I think ) coroplast at a local Home Depot here in So. Ca.. It was on the cart of the customer ahead of me in the check out line. And they said they found it but the associates at the store didn't know they had it. I haven't tried to locate it myself yet. I think it was a large sheet ... But I know for sure it was at least 2' x 4'

The plane I learned to fly on (back on 4th St before the Ont Mills was there) was made of that corregated plastic, it was an Aircore 40 powered by an OS .46 . Weighed a ton but survived my learning curve

Better yet, go collect the ones for your least favorite candidate now. Cuts down the clutter and you can have your model built in time to fly this weekend.

The wires on the esc that go to the Rx are brown tan yellow. They don't always have a red wire. When I get home I'll check and see what my esc's have. On the road at the moment. And yep I hate being on the road. All my toys are at home.

The interest in the corrieboard is that the sheets go up to 8 x 4 off the shelf, and there are also larger sheets in some sizes available to special order. It can be solvent welded, which is a very easy way of assembling, and having picked up a few small samples earlier, the 10mm board is amazingly strong, and the smaller sizes are pretty rigid too, a few pieces of carbon rod down some of the flutes should make it very rigid for some areas.

The local seller also does a high density plastic foam that's a smooth finish on the surface, I've not checked the weight yet, but it looks like it would be very good for things like control surfaces, as it's pretty rigid even in the thin sheet size.

Not sure which way I shall go on that yet, but having looked, it's worth some more experimenting,

Some how it seems a little disrespectfull to have a candidates face on a plane. Especially such a nice flying plane If the guy in there now. Well you know.

I agree, but how majestic would it be to see the plane head in full throttle into a mound of dirt!
