Joby eVTOL

I built a 1:30 scale flying and functioning replica of the Joby eVTOL aircraft:

It has 6 rotors, 6 servos, and operates on a teensy flight controller. It has 2 different flight modes for hover and forward flight and interpolates between the two modes throughout transition. It uses the cascaded angle controller to keep the vehicle level in all modes of flight, with a servo that rotates the tiltrotors with the flick of a switch to a desired angle, maintaining PID control throughout.

I'm unsure of flight time because it's so new, but I imagine it can hover for about 6-7 minutes on a single charge. Need to tune the gains a bit more and throw and FPV camera onboard to get a better sense for how it flies. I think it'll be pretty cool to get the rotors transitioning in view with the FPV camera.

VEHICLE SPECS:
Mass = 320 grams (w/ battery and paint) not bad!

Flight Controller: Teensy 4.0 with dRehm Flight VTOL
Motors: 1404 3800kV xing 2
Servos: ES9250MD Digital Metal Gear
Rotors: iFlight 4030
Battery: 3s 850mAh

3D printed fuselage material: Onyx printed on hacked Ender-3
Tilt-rotor shafts: 3mm steel (should’ve probably used carbon)

FPV would be interesting. I look forward to that update if you ever do it.

Wow, just awesome!
dRehm Filght is one of the only solutions for a vtol aircraft with 12 degrees of freedom and differentiate mixing for hovered and forward flight!

Yup, it's amazing. Unless it's a racing quad, everyone should use it.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
