w3631k

Introduction:

Testing out the KF airfoil. Build has identical components as w3631, except it uses a KF airfoil instead. 540mm

Components:

• Dollar tree foam board
• Turnigy Plush 2-4s 10a esc with 5v2a BEC
• DSM receiver
• 2x 5g servos
• Dragonfly 1306 3100kv with 4x4.5 propeller.

Conclusion:

Dry weight came out to 97g, which is pretty much identical to the other one.

It flies really well. It does feel a bit different than a conventional airfoil. I'd have to fly them more side by side to really feel out the differences.

Update 4/8/20 - This flies great. The 4 in bi blades perform well, although a bit loud. It did get damaged though in a midair collision with a micro warbird. Had to replace one of the servos as the gears got stripped.
