10. Installing Pushrods and Control Horns

40. Place glider upside-down on a roll of tape or a block of foam to provide clearance for the dihedral.

41. Mark locations for center of control horn on bottom of elevons. Poke a hole through each elevon at this location using a small sharp nail (you may also drill the hole using a 1.6mm (1/6 in) drill bit).

42. Locate two 180mm long carbon fiber pushrods and two control horns with attached shrink tubing couplers. De-bur ends of carbon pushrods with sandpaper. Slide pushrod into control horn coupler until it stops, and secure with a drop of thin CA glue.

43. Press barb of control horn (with pushrod attached) into hole that was made in balsa elevon. DO NOT glue horns in place at this time.

44. Hold end of one pushrod centered over aluminum pushrod adaptor on servo. Trace path of the pushrod onto the rear of the pod using pen. This line will designate where you will need to cut a pushrod clearance notch. You will need to cut a clearance notch for each pushrod. Refer to plans for clarification. Each clearance notch should be approximately 3mm (1/8 in) wide. The pushrods should move freely without binding.

45. Remove control horns from balsa elevons and slide pushrod ends into aluminum servo adaptors. Press control horns back in place and secure with thin CA. Make a fillet of medium CA around the perimeter of control horn base. Before proceeding, allow glue to cure completely.

46. Clip excess barb protruding from top side of elevon using a pair of wire clippers or nail clippers. You can now install the battery and receiver in the nose pod compartment, as shown on the plans. Re-connect the antenna wire to receiver. A piece of tape is all that is required to hold the battery and receiver in place.
