This RCPowers Extra300 is going to be my first ever fully fledged 3D airplane. I’m making mine out of 6 mm depron so we’ll have to see how long it lasts.
Wingspan: 900 mm
Length: 915 mm
All up weight: 352 g
Motor: Turnigy C28-30 1050kV
ESC: 25A HiModel ESC
Battery: 3s 800mAh Li-po
Servos: 4 x 9g Servos
Prop: 9*4.7 Prop
All the pieces cut out
Since the depron sheets I can get my hands on only measure 900*400 mm, I decided to make the main plate into two pieces in another fashion than the original.
Here you can see where I made the cut rather then along the whole fuselage.
I use a dremel to make perfect slot for the 3 mm carbon tube
A slot in the elevator as well.
45°ing the control surfaces.
Du-bro hinges on the rudder.
For the motor mount I took the stick-mount that comes with the towerpro motors and removed the unnecessary bits.
The Turnigy C28-30 1050kV Motor in place.
Aileron servo in place on the underside.
I decided to go with two separate aileron servos to be able to have programmable offsets.
I placed the elevator and rudder servos close to the CG and made some simple pushrods.
Rudder pushrod and control-horn.
Elevator pushrod and control-horn.
Receiver and 25A ECS mounted
9*4.7 Prop, I didn’t have any 3.2 mm propsaver at home, so this have to do for now.
352 g All Up Weight
I sold the Extra 300 to a friend of mine a couple of days later.
