Okay, I have seen it as "wing load" and "wingload." Not sure which is right. I have been looking for information about wingload. I figured there is some magic number out there to help with the design of these scratch builds, but I haven't found it yet. Any of you flying aces able to enlighten me?
My current toy is looking like it will have a wingload around .04 oz per square inch. If I calculated correctly, the SC has a wingload of about .075 oz per square inch. I am assuming mine will be okay, but I would like to have more info on this.

Actually, it is properly called "Wing Loading" and is calculated in ounces per square foot of wing. The Super Cub LP in about 10.4 ounces of weight per sf. (25 oz. all up weight divided by 2.4 sf of wing = 10.4 ounces per sf.) Check out the first few posts of this thread: www.rcgroups.com/forums/showthread.php?t=1136470 |

BT, when you figure it out, please teach me. I don't understand it either.
All I know is that it affects your plane in huge ways.

Well, if that thread is correct, my current project calculates to 7.2 oz per sq in. My fidget comes out to 8.74 per sq in. Looks like both can survive with an 8-4 prop. Top calculated speed (never will happen) would be a potential 43 mph. My current project is like a cub. It would never hold up to that. The fidget would be doing circles and loops all the way to the horizon ;D

That link was written by "NoFlyZone" (Chuck) who is a really nice guy and is very knowledgeable about fixed wing RC planes. He got busy around the end of last November and has had to stop writing his thread for a while. I nudged him a while back and he said that he would get back to writing on it and get it finished. I hope it will be soon. Here is another fellow: AEAJR (Ed Anderson) that has written a lot of informational data that is very educational. He has forgotten more info on RC planes then I will ever know. His threads are best read a bit at a time or you will suffer from informational overload. www.wattflyer.com/forums/showthread.php?t=31368It is nice to find that there are so many good people on the various forums willing to share information with others, and to help newbies just getting into the RC hobby. (There are quite a few right here at RC Heli Talk Forum too.) |

Another great link. I usually go into information overload right after, "This is the most important thing to remember..." ;D |
