I also added it on my mix for the 2nd one and put it at something like 30% which makes it actually usable for turning. I've never managed to get a single plane into a flat spin, but I might try on the short nosed one.

There are the ESC's. Those KF4 wings work well, don't they?

The term"flat spin" usually refers to the horizontal plane, I'm talking about pulling it straight up, full throttle/left yaw, Set your mix to 100%, charge up your best battery, and go for it.

BTW: I name all my foamies "Flirtin' With Disaster xxx", as in any plane that lets me fly it is.........
I think I'm on 11, or 13, or so and having a ball with this hobby.

Looks like I first commented in this thread in 2008. Today I actually started cutting out a Funder & Lightning. I tried the tiled v2 plans, but my printer and I didn't get along to make accurate plans. Today I went to a library maker space and printed out 2 copies on nice thick poster paper. I cut out one set for patterns, and kept the other copy for reference. I traced out the v3 fuselage over the v2 plans. That was the best solution I could come up with after fighting with printer settings. I triple laminated some dollar store foam and cut it out on the band saw. I got everything cut out but the wings. I've removed the outer paper. I hope its strong enough for the horizontal stab. It seems weak now, but haven't added the CF. This foam board is over 10 years old, and removing the paper has been messy. I have a few sheets of old blue FFF, so I’ll probably make the wings from that.

Is there a preferred foam board that's currently available? Seems all the good stuff (6mm depron and cf88) is no longer available. I haven't built a foam airplane in a while.
I hope to post pictures and a flight report soon.

Thanks again for the fun design.

Iíve been making progress on my F&L. Iím very happy with my wing. I extended it to 40Ē, because thatís how long my carbon rod was (actually 1m, despite the package saying 40Ē). I left the fff between some plywood for about a day. Itís very flat and true. Iím a little concerned about the dollar tree foam horizontal stab. Iíve added two cf strips. Hopefully that will keep it strong. I have the tail and booms glued up, and just glued the fuse to the wing. Iím letting everything cure overnight. I used some hot glue. It seemed to melt the foam a bit. Most of the joints were made using clear gorilla glue. Iíve used the white quite a bit, and didnít realize the clear is a different product. They look very similar at the store. It doesnít foam up, but seems to make a very strong bond. I was hoping to fly it this weekend, but itís supposed to rain every day. That should give me time to give it a nice finish.
