Had many other choirs to do, so had to lay off the 25 for a few days. Been figuring out a manual way to open the gear doors that stay open when the gear is extended. Servos will handle the doors that open and then close with gear extended and the door that stays open will be operated by the gear. Moving on to finishing the cowls and then the main gear doors.


Stripped the first try at covering the nacelle and used this method.

The air intake takes some fitting and refitting. Really not done fitting yet as the ridge down to the tail cone has to be figured out.

Air intake looks pretty good from the front. Needs to be hollowed out to finish it.

Attached a horn to an arm on the nose gear to operate the gear door that stays open when the gear is extended.

Filed out a slot to hold the horn and drilled a press fit hole for the pin. Will use aero poxy to hold in the horn in the slot.

Will take some trial and error to get the travel correct but the gear arc is 1.5 ins and the door swings at the far end 2.5 ins. The flex copper cable makes the curve to the door with no issues.
