The AirbladeUAV Intrepid 4". One of my oldest quads, and still one of the best flying and easiest to tune. A total workhorse.

The Racekraft 4040s are stiff, I would say stiffer than the HQ V1S 4" props, and are the exact same shape as the older glass fiber HQ 4040s but more durable. They fit the 2800kv F30 motors pretty well.

Surprisingly, the HD footage from the Split 2 on this build is very nice, smoother, and has less rolling or jello than my larger quads. It's flying really well and I'm very happy with the tune, which isn't far from defaults.

When it's time to go check something out over the hill or mess with a low flying weather system this is the quad I tend to grab the most.
