The assembly starts with the lower wing. The ailerons were attached with Zap thin CA on the hinges and a small amount of 5-minute epoxy where the control arm inserts into the aileron. The thin CA soaks into the fiber hinges and then into the balsa slots for added strength so remember not to use any CA kicker accelerator on this step.

I used a Hobbico [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXPB33&P=7]CS-35 Mini BB Servo[/link] for the aileron control. This high power (54 oz-in) mini servo weighs only an ounce and will easily move all four ailerons on the Ultimate. All the linkage was supplied including the keepers.

The upper wing ailerons were then CA'ed in place. Both wings already come with the strut cabanes glued in place.
