    Well so far new project is looking good ..a REAL scratch build...cessna Agwagon...60.5 w/s .....what a task cutting an shaping wing ribs..no problem, I got more time than money lol, but anyway got all fuse formers cut out ....firewall. .just about to have wing complete....here's a question gonna have flaps ..my question is plain flap vs split flap.. From what I've read split is the most "draggest" really slows down without as much loss of lift an can have much steeper descent..an that on take off with split flap not as much deflection to get same lift charteristics with less drag as plan flap ..know it's not to scale ..just like the looks of split flaps..:argue: I

    I have always just used standard flaps. Way easier to put into a plane.

    That is the easy way out, but hardly ever see split flaps, Well at our field anyway...is it true that split flaps generate more drag on decent opposed to plain flaps an it take less flap deflection an less generated drag on take off opposed to plain flaps

    Quite honestly on models this small, you won't notice much difference between any of the flap designs.

    Anybody know if a 4-40 left land swivel ia available, even no returns even from Google, what I'm trying to do is on that wing it has a wing strut from top of wing to fuse. Want to make turn buckle type strut with swivel at wing attach point an 4-40 clevis at fuse attach point..that way no loose parts to lose when assembling at field ...just spread clevis an insert in tab..no loose parts to drop

    Not that I'm aware of. I have never seen one in the years I have been in the hobby. I just did a search and the only thing I found was 4-40 left handed bolts and threaded rod. Which does no good without the clevis.

    Looks like I will have to make an insert...a heli coil...the barrel on dubro 4-40 ball swivel has .2295 od drill that out to #36 drill an tap for 6-32. Next cut 1/2. CR rod 1" long. Chuck up in lathe bore #36 hole an tap 6-32 ...install 6-32 x 1 screw. Turn part around in lathe screw head inside Chuck now bore #43 hole to a depth of .500 an tap to 4-40 left hand. Only reason for 1/2 rod is to hold screw on ctr to chuck up on lathe. Screw into ball swivel put some #620 loctite bearing retaining compound on 6-32 threads, so now cut head off screw with cut off wheel..got a 4-40 left hand ball swivel ....think it will work

    There's 2 ways that could be done make a 4-40 right/ 4-40 left all thread stud then have 4- 40 left hand male swivel. This way isn't as much work. Any thoughts:argue:

    I didn't know you had a lathe or the bits to accurately do 6/32" threads. What you are saying is making sense to me and as long as it works I think it's a perfect solution. If you do what I'm picturing that is lol.

    Got some more tooling for shop today, mail lady brought a 4-40 left hand tap an die today to make left hand swivel for wing strut. Gonna make the 4 tube inserts tomorrow or Monday , have some .250 hex 6061 aluminum. What would suggest on holding stud into swivel..jam nut..put some CA on threads ...loctire red ? I've got some .1875 x .014 wall aluminum to use as strut itself...that an some brackets will probably be some of the test parts for anodizing project.

    I would just make some jam nuts with the aluminum rod you are going to use. Finding left handed 4-40 nuts is going to be a chore. Making your rod a tad longer than you need and just cutting off a nut from it is by far the easiest way. CA will come loose, surely not red thread locker unless you never want it to move again.

    Oh, the plastic end? If so, a slight knurl on the threads and screwing it on quickly should hold that just fine. If you are already holding the shaft into the turnbuckle and the plastic end is held with something else, it's not going to spin out of there. And if there is something that is strong enough to pull the threads out, there is no option that can stop that lol.
