RE: Cold Duck - Build
For the last few days I’ve been focused on the radio, push rods and the engine to engine mount installation. Not working on it too hard though!
I knew the airframe was going to be very light so I installed the servos as far back as possible. The balance looks good with the battery in front of the servos and then the receiver. I don’t like putting the battery behind the expensive PCM receiver but the airframe needs to balance. See image below taken while I was test fitting the radio. Lots of room compared to my first Cold Duck that used the big old Kraft KPS9s. The push rods for the elevator and rudder look like they are going to work very well but I haven’t connected them to the servos yet. I’m using push/pull cables for the nose gear and throttle and I installed the outer plastic cable tubes.
I marked the engine position on the Dave Brown motor mount and drilled and tapped it with a 6/23 tap. I test fitted the engine and it looks good.
