24 foot wingspan fff beast -build thread
Alright-
I'm starting to build my biggest foam plane yet. I'm using pink fan fold foam. It has a plastic layer in the middle so you can peel it into 1/8th inch sheets. Specs- 24 foot wingspan fuselage length ~12 feet weight- hopefully under 20 lbs Essentially a full scale foam Cessna  Not sure about a motor yet, but it will be some kind of big brushless. Here's a picture of the foam, peeled into 1/8th inch sheets. More to come soon. -Hans |

Sounds cool to me. What kind of airplane are you making? This has to be one of the largest RC airplane and certainly a foamy. You can ride in that airplane. Good luck with it.

Should be a great project. I would work out the power system and battery first, though...

It will end up looking like a supersize .40 trainer type-high wing, a little dihedral, rudder elevator control. I have a stack of 26 ribs cut out, they are 22 inches long and a little over 3 inches in the widest part. I'm just making up the design as I go... should be fun.

Good luck transporting it.
 Maybe you should build something a little smaller, like a 23ft plane.

What are you going to brace the wing with? I'd imagine that even with ribs and a built up construction, a 24 foot wingspan will get really floppy and saggy. Maybe a combination of carbon struts and flying wires?

Your going to need a lot of CDR motors
Seriously, what are you going to power it with? |

stjobs- The wings are getting pretty strong. The spars are all glued up. It will have some sort of flying wires though.
intermision- I was seriously thinking about having a CD motor every 2 feet or so along the wing. It would sound sweet with 10-15 little 8 inch props going. However, I think I'll try to build my own big brushless something... It really doesn't need much power. I have an 8 foot wingspan model of similar design flying on a single AXI 2808-24. More pictures later today- -Hans |
