The Dayton spot was a bust, it was covered in 10 ft tall junipers. On the plus side it was biggger than it looked on GE. We did find a couple more places that could be fun. Nothing epic.

I am currently building a JW and wondered whether to hinge the elevons from the bottom or the top. I usually do the top because it looks better but is either way better than the other???

Thanks

You can use shorter horns if you bottom hinge ( assuming top drive ).

I like bottom hinged for the reason Aaron mentioned and Peter Wick recommends bottom hinging on planks.
IMO, the quality of the hinge is more important than location.

I think jonoashton is asking about the location of the hinge pivot point, not the construction of the hinge.
IMO, the best hinge for a JW is 3 sets of tension hinges followed by a full length compression hinge.
The compression hinge only gives too much.


Repost..."Tension hinge/Z hinge/over-under, whatever you want to call them, will really lock in the position of your elevon, up/down, fore/aft, and help to establish the perfect hinge line. A compression hinge alone is difficult to make accurately and doesn't lock it in.
Do a search for tension hinge and you will find some good pics and diagrams.

here are some links...

Here is a sketch I made for the Mako. If you flip it upside down, it will work for bottom hinged surfaces. If you "wrap" the hinge line prior to applying the tape hinge, you won't need to do the tension hinge treatment. The straight piece of hinge tape maintains the tension while the per-wrap keeps the monokote from peeling at the hinge line during heavy use.

Yep, you are correct. I was just wanting to know if the pivot point should be top or bottom. It looks like the general consensus is the bottom so that is what I will do.

Given that the wing trailing edge is carbon and the elevons are carbon as well (bagged), I was considering doing silicon hinges. Anyone tried silicon hinges on a foamie before?

I just recently bottom hinged my JW60, BEST THINK I COULDVE DONE TO IT. Made it way easier to get a good servo resolution off a top drive set up. Good Luck with the hingeing, ive used Alexs secret Ultra Clear Tape and has worked out super solid.

Hey guys got my JW kit in the mail yesterday!!! Now for another question, how to build the wing. I have been looking at build logs all week but they don't tell you which side to lay down on the beds so the other side has a di-hedral. I'm thinking it is the top surface that needs to be in the beds when gluing in the spars. Should be a fun build.

Servos:
I use the servo wheels instead of the arms. I grind them down until they look like the pic. The clevis will need to be ground down to clear the hub. I usually grind the clevis about halfway, this allows about 90-95% of max servo throw. More than enough.
As you can see from the pics this setup is barely taller than the servo and will fit nicely in the JW wing. Don't forget the screws and NO threadLock on Karbonite!!!
