ZIP TIE

Although it should stay in place without it: Use a zip tie!
If your print looks as shitty as this too: Don't worry, it doesn't matter!

Operation

use 4S ~1300mAh high discharge LiPo (min 80C, recommended 120C)
must be launched by hand at 50° Angle and Full Throttle
program your transmitter to 70% expo on both Elevator and Ailerons
limit Ailerons to 60% output, while leaving Elevator at 100%

CANOPY

...is bendable and therefore acts as its own spring while mounted
...allows for fast battery swaps

TAKEOFF WEIGHT

...is at around 800g, shouldn't be an issue to add a GoPro or some 200g Payload, as long as the Center of Gravity is at the red point
