Speed Thing

[Firestar119]

Last year, I built a twin-engined plane built for speed, and only got around to flying it this week (Spoiler alert: It died in a misjudged low-speed turn). It turned out to fly faster than I originally thought, and I'm now designing a successor with printed parts to streamline the draggiest parts of the old design.

Side by Side, Old on the left, New on the right

3d-Printed wing trailing edges inspired by the wing design from Peter Sripol's latest video

Specs:
26.3in Wingspan
24.6in Overall length
3ch Bank and yank
Dual 2207 2450kv motors running 5x5 props
1800mah 4s Battery

The printed parts are finished

The build is finished and ready for its test flight

The printed trailing wing edges and streamlined nacelles should give it a noticeable improvement from the previous version
