Facet Opal

Small Buy GOOD!

Low drag airframe, low weight and good power to weight. This airframe has always fascinated me after learing about the story behind it.

Scott Winton was the designer and builder. He knew the power behind the flying plank. He was able to set many records with this design.

The plane is very easy to print and very easy to assemble. It needs no flight stabilizer or gyro, it just flies well. I was able to fly for 18 min on a 2200 3s and the volts were at 3.9, so i could have gone another 5-10 min. 30 min flights is easly done on a 3,000 3s

Parts Needed

-motor I used https://a.co/d/azU73Qq
-ESC I used https://a.co/d/7PDysZq
-motor wire extensions https://a.co/d/cjrnOCd
-Servos 2x https://a.co/d/0XjUft8
-servo wire extensions https://a.co/d/4mhX4qF
-Battery : depending on your printer settings and weight balace you may be able to run a 2200 3s or you may need something slightly heavier. I ran a 2200 3s and a 3000 3s.
-As for a prop you will need to find a prop that works for you. I'm no expert on prop selection so I dont want to lead you wrong. I used a 6x4 APC but i knew it wasnt the right match. Use whats best for the motor i recommend.
-8mm carbon tube if you feel you need it. My print was rigid enough to not need it. 8-10.0" (254mm) is a good length, just enough to bride the gap in the fuselage.
-1.2mm pushrod with z bends
