To Flatten or not to flatten? What do you think 19k or anyone else for that matter (you too, Sol)? Should I flatten my new wing and put in the ailerons or put in the ailersons and flatten after I get a little more flying time under my belt.
BTW, I don't plan on putting the new wing on until later, when I get more proficent with the stock stuff.

Since I don't have a PKSC and don't know WTH you're talking about, my input will be moot at best. Flatten the wings? Do you mean remove the dihedral? Do the ailerons get added to the wing or cut out of the existing wing? I'm guessing the latter.  |

The Ailerons are cut out of the existing but I've read of people taking out the dihedral and then cutting or just cutting. BTW, I think I damaged my servos during my tree adventure. It STINKS in there. And they seem to be moving slowly. One of the heat sinks on the TX/ESC got hot enough to melt part of the plastic case. I have a spare ESC but no spare PZ servos. Hobbyking to the rescue sometime next week with new HX900 servos. |

I'm sure the other SC owners will have the proper procedure, but I don't think you should remove the dihedral. That's part of the stability of that plane.
I think cutting out the ailerons as it sits would be a workable procedure. Once cut out, it might be a good time to reinforce the wings just ahead of the cutouts with some flat CF. You can CA the exposed wing openings back together with your hinges in place. The cutouts can then be flattened and also CA'd also with some flat CF in between the two surfaces. Just leave a couple of spots in the forward edges of the cutouts to accept the other side of the hinges. Rounding the two meeting edges (the hinged part) will give you better range and less chance of binding.
BTW, this is all out the door if it's solid foam you're working with, but should be an easier procedure. Reinforcing, if it's necessary, would have to be external.
What type of hinges are you planning on using?

What type of hinges are you planning on using? It is solid foam. Pretty easy to work with if you keep your knife sharp, There are a blue jillian youtube vids on this mod. Some top hinge with tape to add built in differential. Others hinge in the middle and add differential via the TX. I've decided to put small nylon hinges in the middle. There is one guy who has a whole series of videos on all the SC mods. He does a lot cleaner work than I can. I still haven't worn the "Great Stuff" off my hands from the last incident ;D I might start on this if I can finish cleaning the garage soon enough today. |

BTW, I don't plan on putting the new wing on until later, when I get more proficent with the stock stuff. I'd suggest using the dihedral with the ailerons at first. Then flatten as the next step and chop off the tips after you're used to the flat wing. By the time I got around to flattening the wing it was already practically flat from the G loads. That's when I put in the CF spars. The way I did the ailerons was to cut them out of an old wing and then did cutouts on the new wing. The thinking being; if I screwed up the first set from the old wing I'd still have a fresh wing to cut. I cut the aileron at a 45 degree angle on the wing side edge and used hinge tape on both sides. It's been to hell and back and still is in good enough shape to be my top wing on the Beech staggerwing I'm building. |

I get the feeling he hasn't had much luck with some of the plank guys. Bet he would get a kick out of one of these foamies though. Ern? Are you out there? |

He, looked over, and jumped over, waving a beer in both hands, the edge quite some time ago. ;D I don't object to having a plank section, but I'm comfortable with what we're doing now; sticking it in the general section, video section, dealer section...Holy cow, it's a virus!

Well, glad to see more guys coming around to the dark side of the flying field. I have been flying both helis and planks pretty much from the beginning of my RC addiction. I like both a lot and fly both as much as possible. As I saw in someone else's post, I am addicted to scratch built foamies. It is simply amazing what you can get $10 worth of foam to do. I am actually just getting started on the build of my first "slimer" plank, a Hanger9 Pulse XT 40 w/ an OS .55AX providing the power. |

Dammit Tony, don't be showing off any pictures of that one around here. I drool over ALL the Hangar 9 stuff.

I'm really not trying to enlarge the scope of this thread, but this past weekend I went down to the city auditorium to see a free competition of rubber band powered airplanes. People came as far as Atlanta to here in Colorado Springs to participate, and it wasn't even a big event. I didn't think that it was going to be very interesting, but it was really fun to watch! Wingspans were from 12" to about 20" and some planes weighed less than a dollar bill. There was even a catagory for 2 grams and under. With a 37' ceiling, people were posting up to 10 minutes aloft, and I was told that with higher ceilings, flights up to 18 minutes are possible. These are the most lightly built planes I have ever seen, and wing frames were no larger than 1/8" thick sticks. If you ever have a chance to attend a show of these planes, go see them!

Looks like fun Dube...It's a "gateway" plane for your full blown addiction. Scars post reminds me there are indoor elec. planes that can fly for unbelievable lenghts of time. I think the record is 15 HOURS. No, it's not a typo...15 HOURS. |
