All channels not reversed incl throttle, except rudder.

That is strange... normally the gain works were >50 is heading hold and <50 is rate mode.  If your gain channel is not reversed, then the earlier numbers would be in the wrong mode.  Have you verified the mode (HH vs rate) by observing the light on the gyro ?

Ashta Ji,

For a non heli guy what you have achieved in your first attempt on the tri-copter, "it is absolutely fantastic".   {:)} {:)} {:)} {:)} Myself being a non heli guy many gyro settings, tweaks and mixing posted by you is difficult to understand.  I have to get onto some serious reading on heli setup and mixing.

I can but only fathom the level to which you have gone into the details of the setup of this flying beauty.  But at AUW 1.1 Kgs, seeing it fly itself is an absolute pleasure.

Guys like me would be fortunate to learn in some more details of the same in basics of the setup and even basics of the swash mixing, rate gyros, heading hold gyros, their control from radio and various radio setups for the heli mode and how the various percentages of the gain setup is affecting the flight of the Heli/tri copter.

Ashta

surely Anwar. had spent lot of time on this and confirmed.
Pl see my Video of testing Tri with Gyros.
I first connect a speed controller and motor to Ch3 and see that the motor is turning fast when i throttle up.
Now i connect a servo instead of motor and check which direction it moves (cw/ccw) when i give throttle.
Now i connect W/o gyros and ensure proper travel of servo wrt Aeleron/ elevator inputs.
repaet them with Gyros.
The motor Gyros (3nos() gain is controlled by Ch3, Throttle.
100 is rate mode max gain
0 is Hold mode max gain. Gyro light comes on from 0 - 45.
Since i give -100 for pitch in Swash, this makes sense, is'nt it?

Thank you very much Sundaramvelar.
I did spent quite some time reading and undrestanding. Apart from that there is not much frankly...
thanks one again.
I am again Out of sation for some time and may not be able to reply to posts.

That is why it makes sense... had missed that part !  Somewhere it had to be reversed, otherwise it is always >50 that is HH mode.

hello,
i have done some more work with my TRI.
1. Instead of Pine booms, i have made it with Aluminium channel, embedded with wood. Makes it much stronger and added weight of about 100 grams.
2. The yaw mechanism is more strong.
4. Made it foldable using simple clips.

Pl see the attached photos for clarity.

Also i tried to fly my tri in my garage which is only 8x 6 feet flyiable area, with aheight of about 6.2 feet. It is a challenge but worth for learning.
pl find a short video. pardon be for the poor quality, its again shot thr my crude HAT cam.

Thanking you

Good and neat design.. {:)}
There is one guy(rcexplorer) who has built a tricopter. I am a fan of this guy.You can see this and improve yours too...

thanks Foamybuilder. though i have gone thru that as part of my extensive reading before i attempted this. thank you

Ashta bhai - Nice flight :thumbsup:

Looks like you should do some tweaking of the pitch curve, so that the landings can be more gradual.

Hello Ashta sir, looks like you have switched your allegiance from planes to copters  :) .. Thats a really cool 'Flying object' you have made  ;D .. I think you are not seen in jakkur these days? any plans to come to jakkur in coming weeks? hope to catch up with you and all your new scratch builds some time.

cheers
