Opener Blackfly v2

Electric Ultralight Fixed Wing Amphibious VTOL Personal Aircraft.

Based on the real thing.

Instructions:
This unique aircraft is a hybrid “drone” slash biplane. It transitions between VTOL and planar Cruise much like a V-22 Osprey, except without any complicated moving parts! The whole craft is “fixed” and pitches 90 degrees to perform its transition. This elegant approach requires an advanced flight control system which I have mimicked with a gyro to assist in vertical hover stability.

How to fly:
The gyro is on by default, it will automatically attempt to point you straight up for takeoff and landing.
The propellers are on a manual pitch control “VTOL” to more accurately mimic the electric motors and give responsive altitude adjustments for VTOL operations.

Step 1: set the VTOL lever to bottom (zero prop pitch).
Step 2: set power to 10-20% (it doesn’t seems to matter)
Step 3: rapidly slide VTOL (Prop pitch) to at least half.

You should leap from the ground just like the real thing!

Step 4: adjust the trim (gyro) up to pitch your nose down to begin planar flight.
Step 5: turn off gyro (group 8) to fly like a plane.

When you’re ready to land (anywhere! This bird is amphibious!) fly to you desired landing area
Step 1: reset gyro to center (straight up!)
Step 2: adjust VTOL (prop pitch) to 10%, basically no thrust
Step 3: turn Gyro on (group 8)

Your craft should rotate itself into a hover automatically.

Adjust VTOL to control descent rate! Sweet spot is about 15-20%

    @motorfiets v2 is here! Much improved VTOL performance and also amphibious now.

    You can really see the rocking takeoff motion if you power up to 5% for second before going to 10%. This gives the lower motors a chance to spin up first which launches the nose up real quick.
