Thumbs up Largest Foam plane built

I have seen a 50 ft.(wingspan) foam plane built in another forum! I and others, I am sure, would like to know what is the largest foamie you have built or are currently building. This will probably be with fan-fold foam I think, as I have heard there is a grain direction simular to that of plywood for strength. I would like to see SIX foot and larger,but , you may show anysize. I would really like to see anything over 12 foot though! I would like to build a big one and I hope this might help me find the big one to build. Feel free to include all pics and drawings you like. I am thinking that this is the blue fanfold foam.You may include a stick built plane too. Thanx for visiting. Scott

That's amazing! I can't believe how slow it can fly and how softly it touched down. I would never have thought something that big could fly indoors either.

I carved this 8 footer outta the 4'x8' poly styrene "Insulfoam sheets. I have glided it once but haven't motored it up and tried to fly it. It weighs about 4 lbs. without motor and battery. I also did a 8' flat foam wing outta the Insulfoam. As a concept prototype. Powered with a E-Flight 25 motor as a tractor and it did fly on elevons ( straight ahead) but was turned over by a slight breeze on the 1st attempted banked turn. My conclusion was that a 8' foamy (flying wing) needs completely calm wind conditions to avoid being blown over in a banked turn.Of course then there's Chellies 10' w.s. 11 lb. Bipe. I watched and flew it and the breeze didn't hurt it at all. LOL And don't forget Imopar69s 14' flying foam wing

That B-17 is awesome. I just noticed how old this thread was and that the originator is banned. LOL But it's an interesting subject.

That would be a cool power system huh? Probably non scale verticle stab. fins would help. But I was trying to avoid that route. Here's a little flying wing B-2 sorta scale that flew well without fins.It had a KF airfoil.

The main trick to flying big, lightly loaded, slow flying foamies in the wind is to have LARGE control surfaces with lots of throw and BIG HONKING servos to power them

I love flying my Mega Capricorn (60" span x 84" long, 3300 sq inches of wing area) in the wind even though it has a lower wing loading than most thermal gliders.

Thats because it has huge controll surfaces (I have just about 1000 sq inches of elevons and about 500 sq inches of rudder) with 45 degrees of throw and hi torque digital servos driving them. You have to be able to fight back at the wind by beating it half to death with BIG control surfaces

A fair amount of power helps too
