Flymanta Avatar on a Football Ground.

Here is the FlyManta AVATAR movie shoot made this week-end with a 2 axes Direct Drive Brushless. I was at Cité Universitaire in PARIS where i live. (A kind of Big Campus for foreign people. All nationality is represented here)

FlyManta particularity is the YAW movment made with 2 Servomotors on front Arms.

The Yaw command is the same than a normal Tricopter, i just change a bit the code to send this command to 2 differents outputs.( you could use a Y cable too to do that).

I've made a full photo album of the construction here : https://www.facebook.com/media/set/?set=a.10200561968160143.195432.1486931539&type=1&l=1fe6997c69

it's a public link that you can share guys.

Fast is the main advantage of the Yaw made by twisting the arms, i'm using liitle servomotor but the weakness is the center plastic pinion wheel. So using a metal one is better.

I've remarked that the Yaw on a simple Tricopter is not flat... because of the inclinaison of the back motor.

I'm using GO PRO2 and the RC Timer Direct Drive Gimbal (a bit heavy !!) a carbon one will be better to enhance my flight time. (7 mn with a 1494 gram Tricoptere)

The Batterie is 2650 mAh (300 grams)

Flight Mode is HORIZON a mix between ACRO and STABLE (ANGLE), Acc influence is lowered with angle.

Hope you like it Guys !

(Moderators- User informed to add content to post, I.E video/pics)

Hi everyone,

From month now, i finaly decide to make that build that i wanna share here.

The control is AIO Pro card with Multiwii 2.1 don't know if APM can handle the Bi Copter configuration ?

I did it with 10 mm aluminium arms and plastic blocs. hope you like it !!!

Next Step is the command. Enjoy !!!

Hi Guys, (and girls ;))

I've tried today the Moving Average Function for smoothing the Gimbal servo.

Here is my result with 300 Hz refresh rate and a windy condition. I'm happy because this average really help.

I still have vibration but less than before. i've notice that the CG need to be well center to have better results.

Is someone have tried the Gimbal on APM ? i wanted to compare with Multiwii.

My IMU is the most simple with Nunchuck and WMP.

Some advise to have better results ??? i'm using Flyduspider frame.

PS : you can cut the sound ! to lazy to edit that one.    Enjoy !!!

MultiWii 2.1 HEXA with GIMBAL

Hi all,

Here is a video i've made with MultiWii 2.1 and my Hexa (Flyduspider) to demonstrate how works Gimbal command.

I have the minimum conf with Arduino Pro Mini and a PPM Sum card to save two output need for Gimbal command, and one for Cam Trigger.

In the code you can chose between 50 Hz 160 Hz and 300 Hz for the servo command, in the video i'm on 50 hertz to start.

My first loop!

 

When I saw Warthox do a loop with MultiWii I was so impressed and inside my mind i said : one day you'll make one and I kept this dream inside a little box of my head. Today was my day when i decide to try .... Well I'll let you watch the film.

 

One thing ;) i made it with MultiWii 9.0, someone can tell me if i can try with APM? I never saw someone do it with APM ????

Why OCTOV is a good choice for Aerial Movies

 

 

Hi everyone,

 

After several weeks of Flying with this plateform it's time for conclusion.

Avantages of OctoV : Payload can be 1 Kg

Autonomie can reach 5 mn with 4S 5000MAh

Against the Wind it flies well

 

One time the OctoV just fall down from 20 meters (no more juice) but the plateform stay horizontal and the Camera was safe :)  3D camera (really expensive).

 

I Fly with 2.0.42 ... 10 inch propeller and this stability is perfect.

 

Can be hard to YAW when the total weight is 4 Kg (YAW PID may need more P ???).

 

For the construction i use 1 meter Alu (15mm) without any cut :)

 

I encourage everyone to take the risk of building tha platform, you ll not regret !!! I finally sell it to a movie companie :) makes me sad but technology need to be share to those people. They want to make a movie in Maroco ( they told me about a car race) and for sure they need me to pilot the machine. I FOUND A JOB !!! MUM can be proud now :)
