General Assembly of Molded Models.

By Tom Copp

If you'd like to see specific assembly details of a few models go here.

This instruction sheet will cover about 98% of the models available. Most of the new molded ships share similar servo installations for the wings. I placed them into types as follows:

ControlHinge LocationControl Horn locationServo arm direction

Where Top refers to the the Top surface of the wing.

Find your configuration type on the table for your model and set up your Flaps and Ailerons  like the example drawing.

Before installing wing servos you need to have a few things ready to go.

General Info: I know this is basic but use it as a refresher.

Wing Servo install
Flap servo 1.jpg (69546 bytes) I tied off the extra wire length and secured the connection with some wax string or good hi heat tape.
Servo bond 3.jpg (51335 bytes) Make sure the servo cover will fit.
Servo bond 4.jpg (54602 bytes) Especially here. You might have to flip the servo if your covers are different. Check all this before you mix epoxy.
Servo bond 1.jpg (65153 bytes) Ready to epoxy in. Your radio is set up, centered and checked for travel and direction.... right?

I usually place the servo arm 1 spline forward on the aileron for more up travel.

Servo bond.jpg (56950 bytes) 5-minute epoxy and cabosil. That's all you need to form a good bed for the servo. 
Servo bond 2.jpg (54038 bytes) Gently push the servo into position. Apply light pressure to the servo arm side first to squeeze the epoxy away from the arm. You want a small bead of epoxy to ooze out from around the perimeter of the servo. 
Horn1.jpg (57026 bytes) Measure the height of the control horn and epoxy it in place. Yes the hole is threaded but you should epoxy the horn in to get a 100% attachment to the control surface.

Make sure the other side is exactly the same.

Ail servo finish.jpg (65308 bytes) All done less cover. After the link is centered and the radio is completely programmed I place a drop of CA on the threaded rod to eliminate any slop in the clevis.
Flap horn 1.jpg (42606 bytes) Flap control horn. 

The wiper is relieved to allow the clevis to open and capture the horn. There is no top fairing on the Pike, the connection is almost flush with the top surface.
