Hi guys!

I'm building a 75" Tempest Mk. V from Ian Baileys plans ([link=http://user.tninet.se/~ytm843e/bailey.htm]Ian Bailey project[/link]). Made some modifications to the flaps, to achive a more scale-look:

I took two Robart 3/16" Super Hinge Points and separated them. The holes were enlarged to accept short pieces of brass tubes (3/32" inner dia.):


The flaps are made of 1/16" ply, four notches are cut where the hinges will be. Three pieces of 1/4" carbon fiber tubes are glued with Slow-Zap along the leading edge.
Pieces of 3/32" brass tubes are epoxied inside the carbon fiber tubes. (If I had found plastic tubes with correct dimensions I would have used that instead.) A 3/32" piano wire is cut to proper lenght. :


The wire is slided into the carbon fiber/brass tubes, don't forget the two middle hinges! The wire is secured with a FEW drops of CA at both ends. The outer hinges will be loose until the flap is glued to the wing.
The ribs are made of 1/16" balsa, more details will be added later.:


Full scale flaps:



Question: The Tempest has four flap sections, on the plans they are operated by a single servo via push-rods and four bellcranks. Is there an easy way to operate the flaps using two servos, via a Y-pushrod? Or is the best solution to use four smaller servos? How large/small servos do I then need?


Cheers!
