Ah... not... yet. I haven't ordered the Power Pack. I have hand cut bell cranks, screw mounted through plastic barrel bearings to a base plate. I've cut a four way servo arms into a bell crank as well. They work great. In this case that would mean cutting off the small tab from the center (old rudder location) support, then mounting that bell crank to a post on the top rear edge of the support. Now... that changes the required location of the attachment on the rudders. Since the bell crank left/right arm is centered, to get equal throw and motion from the dual rudders, isn't the new attachment location in the center of the rudder, outboard/aft of the pivot point?Do you have any of the spare servo output arms, horns, disks or similar? If you have a selection then the whole process can be quite simple.
Have fun!
Just doing some "Stinkin' Thinkin'" over here. Cutting a slot in place of the servo horns on the rudders... glue in the end of a servo arm with a pocket for the wire to freely move.

Do you have diagram or pic to post. Most times it is better to see set up. Thanks!Just doing some "Stinkin' Thinkin'" over here. Cutting a slot in place of the servo horns on the rudders... glue in the end of a servo arm with a pocket for the wire to freely move. Must open paint program to see....
This is the sort of simple hack I would use. Refining the design or use of hand made control horns ets would work as well.Ah... not... yet. I haven't ordered the Power Pack.

That'sa what I was thinking. Maybe after she gets banged around a bit... or after getting my power packs. I know I'll have plenty spare. Hey, will a servo horn fit over a BBQ skewer? Anyone... Anyone... Easy pivot post for the bell crank.This is the sort of simple hack I would use. Refining the design or use of hand made control horns ets would work as well.

The 3 mm skewers I use are a very tight fit. with a little work they free up sufficiently to use as a hinge or pivot.That'sa what I was thinking.

Next... Power Pack/s!The 3 mm skewers I use are a very tight fit. with a little work they free up sufficiently to use as a hinge or pivot.
They are great for use with the servo horns/output arms to provide things like the rudder arrangement mentioned previously as well as guy points for guy wires and even wing bracing struts.
Have fun!
I used to wax poetic about my motorcycle. The fever? You've got it bad, man.It's after midnight... my eyes droop at the revelations that appear before them. Springing open as ideas flash through gray matter that fights for sleep. Another day awaits me, yet... I vow to take up arms against boring everyday, and will myself into dashing ink with aged fingers across yellowed paper. Knowingly smiling, as if madness isn't near... tomorrow... to reason the revelations into something near a sane and flyable objective. Finally... satisfying smirk... relax to take in the accomplishment, saying goodnight to the light of my screen, and a warm hello to the darkness of closed eyelids. Sleep, for to dream... of flying machines and sealing wax... returning to the boy who believes in... dragons.
Want to figure out a few things first. I'm thinking removable camera platform, so Sky-Truck is Multi-Purpose bird. Cams, power and controller on sled with Plexiglas window in belly, controller plugged into receiver. If I can get it to fit, possible mount under rear of gear support box near nose, locked in with load release I'm making out of tow line release unit. I want to be able to open cargo door and release cargo separately. That way I can put night-vision infrared LED's on the sled as well, powered by same pack.
I got the "White" versus the "Clear" I bought earlier. Gonna try on some scrap first. Also hoping to raid DT, see if they will sell me a BOX unopened. When put into racks each piece has one corner crushed. Even on the Black.
