Arduino/nRF24L01 – Nutball !

A self designed system, using own written code that now finds itself on a popular Nutball type aircraft.
The first flight section tests were in 4-5mph wind.
The second flight section was in 14mph winds, as reported by wunderground.com for 30 March 2016.

The code itself is highly experimental and therefore not available for download, for safety reasons. There are some well established other programs such as Cleanflight and ArduPilot that are much further along – i just wanted to code something from scratch as a challenge.

As such, there are 1024 steps resolution on 3 channels, plus a 4th switch type channel, for lights or guns (as on the previous video of the Mitsubishi Zero scratchbuild).

Nutball spec:
12″ Dollar Tree foamboard (paper removed)
10g brushless, 5×3 prop from a Sky II toygrade of years ago
10A speed controller
2x 3.7g servos
3.3V Arduino Pro Mini, with battery to the RAW input
nRF24L01 2.4GHz module – also one in the transmitter – short range, to be upgraded
7.4V 260mAh 2S Venom lipo
Throttle, Rudder, Elevator + switch channel
Flight time around 8 minutes
AUW 2.9oz

Also maybe of note, the servo links are made from pieces from a metal cooking tray, with the legs from capacitors and heatshrink tube to connect.
