Cobra is a radio controlled vertical takeoff/landing drone capable of long distance mission with challenging takeoff and landing terrains. Completely 3D printed, this aircraft has autonomous capabilities such as auto takeoff/landing, waypoint missions, and auto return to home.
This specific build was modified to use two front tilting motors in lieu of 4 lift + 1 pusher motor configuration. Power system also deviated from factory recommendation in favor of higer voltage setup.
Equipment Used:
STL file from titandynamics.org
Matek F405-VTOL flight controller running Arduplane 4.5dev
T-Motor V3115 640kv motors
APC 12x6E Props
Lumenier 51 amps BLHeli_32 ESC
TBS Crossfire radio link
Radiomaster TX16S Radio on OpenTX
Emax ES09MA servos
Generic Robotics servos for motor tilt (www.amazon.com/gp/product/B07...)
6s-5000mah Lipo battery
DJI Vista FPV video system

Beautiful - excellent work! Just about to assemble all the printed parts for the Cobra (LWPLA) and considering using tilt rotors in front too. Got any tips or close up photos of your setup? Is the tilt mechanism from one of the other Titan VTOLs or something you designed your self?

@hobbyconcept 5 месяцев назад

Thanks! The tilt is from Titan Viper with the boom mount enlarged to fit Cobra's booms. It basically uses a pair of robotic arm servos like these: www.amazon.com/gp/product/B07CMBMWZW

Amazing build! What is your takeoff weight? Do you think it's a good platform for mapping with a 500-gram payload (mapping camera) and at least 1 hour of flight time? Is there free space inside the fuselage for a mapping camera and a bigger battery? Thanks!

@hobbyconcept 5 месяцев назад

My takeoff weight with 6s-5000 battery was about 3700g. Designer listed 6KG max takeoff weight so your camera should be no problem. Plenty of space in the fuselage as well. The plane was intended to have 4 lift and 1 pusher motors, running on 2 separate battery packs. Example setup would be small Lipo for liftoff/landing, and 21000mah Li-ion for hours of forward flight. Only problem with this airframe is the lack of landing gear, so you will need to build a landing gear to clear the underbelly camera. They also designed the "Viper" which has 3 motors with camera bay and landing gear, which might be better suited for your need. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-32AOw3QLhmQ.htmlsi=YBN9MgtHZuraX71d

What is the advantage of eliminating the pusher motor, in terms of flight autonomy? Will you use Inav 7 in future?

@hobbyconcept 4 месяца назад

the cost, complexity, and weight of an additional motor + ESC. But for long distance mission the 5+1 configuration is favorable as the single pusher motor can sip very little current. Ardupilot is much more configurable and reliable for VTOL application as it's matured over last decade.

@flyingRich 4 месяца назад

Cool design! What are the flight times you are getting?

@hobbyconcept 4 месяца назад

Getting around 10 minutes with 6s-5000 lipo. But it's designed to take 6s4p 21700 Li-Ion packs for much longer flight.

@Urko76 5 месяцев назад

Amazing Maiden flight!!! Is there any significant different in flying performance between Ardupilot 4.4 and 4.5? Thanks!!!

@hobbyconcept 5 месяцев назад

It's a dev version so no difference yet.

great looking plane! Do you mind if I use a image from the video in some ArduPilot release announcements? The photo of the old porter I tend to use is a bit dated, and this plane against the sky looks great

Leaving the captions on the screen a bit longer would be nice. Sucks trying to watch the video, read the caption before it times out and having to rewind.

@hobbyconcept 5 месяцев назад

sorry about that. Somebody complained the subs on last video was too long. That's why I shortened it.

@joepopplewell680 Месяц назад

Wouldn't the weight of the joint on the two forward motors be too great a weight penalty to be worth it? Plus you then need to power 2 motors for forward flight, and they can't be optimised for both hovering and forward flight.

Did you do manual tuning?

@hobbyconcept 5 месяцев назад

This video was untuned maiden flight. Since then I've enabled notch filter and ran autotune to make it more locked in. Also added feed forward and did some manual tuning to eliminate the yaw wag.
