There are quite a few VTOL conversions of this plane, but many are with tilt-rotors. This requires 2 extra servos, an extra motor/ESC/prop, a rear motor mount, and replacement tilt mechanisms for front motors ….. this is a lot of extra weight.

Instead I’m going to keep close to the stock weight (no extra motors/servos/mounts), replace the tail assay with a simple ‘stand/tail-fin’ and configure a stil-sitter setup of the flight controller!

PNP Heewing T-1 Ranger, converted to a flying wing as a VTOL Tail-sitter.
- Motors: stock replaced with 1606-3200kV
- Props: 4X2.5 2-blade
- Flight Controller: Matek F411, running Ardupilot 4.2
- Tail boom and surfaces replaced by 5mm Corflute fin/stand
- Wingtips fitted with plastic cable ties to balance
- Battery: Li-Ion 3000 mAHr
- Camera: Foxeer T-rex 1000 TVL
- VTx: 5.8 GHz with Fatshark cloverleaf

This is the maiden flight - a simple hover test.

Power required: 8-9A for hover. Weight 790 grams.

Standard Ardupilot configuration for Tail-sitter, using the online guide for setting initial variables.

Next flight will be transitions to/from level flight, and other hover modes (Q-Hover, and Q-Loiter), plus tuning the transition rates and trigger angles.

Also need to fine-tune CoG, which is calculated to be at 40mm behind Leading edge.

    Nice experimenting. Look forward to seeing how progresses. You got my attention by using the T1 as base for the build vs. F1 which is already a flying wing.  Makes sense, as a tail mod is easier that doing bi-motor wing mods.

    Is Matek F411 correct? Thought it wasn't supported due to limited memory. Curious, as I have a spare F411-WSE.

    Could you fly this as a plank? 🤔 I have a T1 kit still in the box and now you have me curious 😎🤙
