Second Pilatus PC 21 build


So I feel I am far enough on this build to start sharing some photos and videos. I've been working on this for almost 2 years on and off.

51" wingspan
total weight: 3000 grams
motor: 4250 500kv
battery: 6s lipo
ESC: 60 amp plush
Prop: 12x12"
Spinner: 3" from HK (carbon fiber)
Landing gear: from Avanti S freewing (perfect fit)

I tried 3D printing the nose cone, but I couldn't get it balanced at all. The cowl/exhaust is 3D printed

Thanks, I'm using a step-down transformer wired to a dimmer switch.
