Benefit should be efficient with the additional more complex tilt plane, so large propellers should be used, also lower prop should be smaller diameter and higher pitch as it is under the smaller and faster down wash.
therealfox thks, yes, it was a diy flight controller! The system is more stable when the center of gravity is low as you can see in the more recent videos. Rgds
Am I wrong in thinking fewer motors means less vibration? I would have liked to have seen it yaw. Scale that up and there's your flying car! (I don't care for the one with props at groin level.)
using contra propeller technology very nice, good idea simplest and powerfull
Awesome. No comments, very good
Thats very cool! Congrats!

Present, the Jack Russell yes! I'm working on it! Thks
The first flight is itself so stable
If you mounted stuff vertically it would be sleeker and cause less drag.
nice machine man!
wow, cool. very stable! how many use bldc in there? can that yawing?
bellisimo
it looks like a flip-flop but its cool
thanks
what servo did you use?
Lit.
Hi!! Simon, May i Use a controler with less chanels?, do you use all the 12 chanels from your controller? you have a great job!
Any news on that? Could be a bit more stable. Maybe with new gyro systems in new flight controllers it could stay stable

Nice
I want to know the name of hardware which control the inclination of motor. plz~

But can it do flips?
Cool! How long before I can get one?! Or 2?!
Joshua Roy Depends on when you want to build it yourself
so nice
Good
probably good for low altitude.. bat I feel like it will have a problem flying as soon as you put a camera gimbal on it. good stuff!
nice work!
Thks!!
how do you change the torque of one motor over the other for yaw movement? Do you control the throttle of both motors separately ?
yes, like a classic birotor, rgds
what did you use for the flight controller
Custom FC but you can use a normal FC as well
Looks good, however, how can yaw movement be controlled using only 1 motor? Can you give some updates about that invention?
Yes, it's a contra rotative brushless motor. Yaw is controlled by the speed of each prop. More updates on diydrones see vgrsystems blog. Thanks!
Yep, it uses the centripetal force.
that drone use a 4ch radio ?
Yes a 4ch radio but need more channel to tune the PID in flight
why is this a drone and not just a helicopter?
Zach Allen drone mean uav . It mean there is no man control the vehicle on it thats why is called unmanned Ariel vehicle
Just curious, what servos are you using? They must be very strong.
I thought but actually not. A micro digital servo like ds385 is enough.
But doesn't a brushed servo eventually wear out?
No i don't think so. Forces applied are not so strong.
Kenneth Wang Hi Kenneth!
OK thanks, but wit fc are using? I got kk2 mini And a cc3d and an APM ? on 4s !
It was a custom fc but i tried a CC3D without any problems. I used librepilot. Nevertheless I think tha t3s is mandatory for this motor.
Very cool drone! Btw, which program are you guys in your Custom FC? MultiWii, APM, or your own custom code? I'm very curious go know.
Thks, It was a custom firmware programmed for PIC32 from Microchip. Interesting development but I stopped and bought a CC3D revo instead. rgds
VGR-Systems very cool! Regarding the CC3D, are you still using a custom firmware?
no, It's librepilot firmware librepilot.atlassian.net/wiki/display/LPDOC/Welcome
VGR-Systems Awesome! Thanks for the info.
Regarding the librepilot firmware, did you use "custom" as the setup for vehicle configuration?
How do you control yaw on this vehicle?
Mahathi Bhargavapuri with different torque applied to the upper or lower prop (contra rotating motor)
I want to convert my 450 helm into one! wut sise props do u use, an wut kynd of brushless motor an kV, how many cells ?
props : antigravity carbon 9"; contra motor: www.maxxprod.com/mpi/mpi-266.html; lipo 2200mah 3S; rgds
his invention will mark a before and after. Especially for FPV
OK , Wut is t3s ?
lipo 3S sorry
i need Command program this drone by arduino
How many degrees are leaning engines?
Rumcajs x about 15deg for this frame.
Thank you - frame looks great :)
I think of similar design - but the coolest are the dimensions, just in time for a little quick trip
VGR-Systems are ur item on eBay ?
Very nice.
helicopter
why it is not stable moving alot /?
to show the translation capability. rgds
do you have a yaw control ? and can this idea be made on 2 gasoline motors ?
Yes, with a different torque between the upper and lower prop. Why not with gasoline motor but not so easy to design a contra-rotative gasoline motor.
whats so different than a coax heli, but an ugly one.
