Did you know that Foamy Day is May 28th. It replaced Balsa Day a few years back.

Looks good Dave. You may have noticed on the last few I've build, I made the fin smaller, both for looks (a personal thing) and weight. These LAR designs are always difficult to balance with too much added bit n' pieces at the back end.

The last time I flew my bigger blue foam one, it didn't quite do what I wanted. It used to fly like on rails, but for some reason was giving me grief. On inspection I found the motor down thrust no longer existed. The foam had compressed from smacking the ground a few times the last time out. A boiling kettle of water fixed that up and now it back to it's old self.

So, you may have to fine tune the down thrust as it's that important on this design.

I know you'll like this design, it's like a close cousin to the NutBall.

"A boiling kettle of water..."
Do you just use the steam plume to heat the spot, or do you do something drastic with the hot water?

Dave:
Thanks - I have been wanting an excuse to learn SU.

For dents, dings, gouges and compression on 'most' foams, just pour boiling water over the blemish and it will expand back to normal. How much depends on how nasty it is.

I started this thread for sketchup, when I started playing with it..and I post info as and when I find usefull bits.. I mostly do simple plans, but others there are doing some good scale work, and there are some usefull bits of info on the thread..Its a great program for free, and for foamie plans is a quick way of getting a plan with dimensions that you can scale to any size with just a couple of clicks

Check out the ailerons on mine in post 193. I added the tabs just to see because my Osiris has them and rolls great at slow speed. They seem to add a boost and need to be directly in the prop wash.

We have several flying now with this mod and it seems to roll with more authority at lower speeds.

Thanks, Dave:
I've been following that thread for a long time and have it on my LIST of projects to attack. I have been interested in SU since I attended SIGGRAPH a few years ago and went to a half day seminar on it - they clicked and gestured through it so fast I didn't really get it all. Then when I discovered that the curves I wanted weren't as easy to do as the stuff demoed, I put it on the back burner. But all of the great examples on your thread have reawakened my interest.

goldguy - thanks I will put the pot on and attack some of those dents.

Can the entire airframe, including the wing, be built from 6mm Depron? Looking at a 19" or 20" wingspan here.

You can use whatever foam you have on hand. Just make sure the bottom fuse is strong enough to hold the airfoil to shape if there's a lot of tension when bent. The great thing about this design is, you need bracing at the TE only, the bent airfoil produces tremendous strength to the foam, even EPP.

A fellow foamy flyer built a 36 incher from 3mm Depron and it was amazing. It held it's shape for about two years until it was finally scrapped.
