Title: Y4-Copter Post by: mohan keerthi mm on June 25, 2014, 10:10:54 PM This is my first project on "modified y4-copter". i am very happy that my copter flight was awesome on my exam after a two months struggle.. initially the copter was not stabilizing... after making necessary settings on kk2.0 control board i achieved the stable condition on my copter... i modified this copter for roll and pitch movements by adding a new tilting mechanism of motors along with propellers by using 2 servos......

Title: Re: Y4-Copter Post by: Shyam Hembram on June 27, 2014, 10:25:02 AM one of the new designs great, by the way whats the advantage of inverted motor???
Title: Re: Y4-Copter Post by: mohan keerthi mm on June 27, 2014, 07:57:38 PM Using inverted motors on rear side... we can eliminate servo in rear side as we usually see in tri copter.... inverted motors makes the counter balance on rear side...
And also, the pitching and rolling are new mechanism which i have used.. i used 2 servos one for pitching and another for roll movement.. see the below pic which will clearly shows.....

Please share the mixer editor settings and flight video, would like to see how its flying. Apart from the fact that you did something different, whats the point of adding servos for pitch and roll since you are adding more points of failure on your craft? Title: Re: Y4-Copter Post by: mohan keerthi mm on June 27, 2014, 11:39:46 PM when i started working on it, i was not knowing about the self level and all.. i started with zero knowledge..
while pitching of forward and backward the copter tilts to an angle of 5 to 10 degree... to avoid the whole copter tilting.. i thought of tilting the only motors by using servos.. where the copter meets the self level and motors will be tilted according to the movement of copter... i used servo control on auxiliary channels 6 and 7.. Using Mixer Editor we can configure any type and any size.. that was a great experience while setting those values.. but, our copter works only with kk2.0.. it doesn't work with kk2.1 control board.. i tried by replacing with new board also but it was not working with kk2.1.. after installing kk2.0 the copter stabilized...

Yeah, Your art work of engineering and selection of materials seems really good and well planned. awesome job, but i do not see any advantage of it. Did you meant to say instead of slowing down/speeding up the motors you made the pitch and roll by using servos to tilt the motors. aint that would be more complex. also, how you could get more flight timing with 2 motors instead of 1 motor and 1 servo?
