Yes.. and the speed controls... kindly put them upside down. the heat sink is not getting enough air (it is on the side where there is no sticker). so that will eventually result in energy loss and decreased efficiency...

Ha Iflies. Hers is a short video, from Hoskote Today. I have never flown a heli and first time flying a Tricopter.
It took off well and was flying very stable. But i was very nervous and landed it fast and that too in to a pool of water.
Kept it for drying.. Hope that nothing has gone wrong.
Oh.. what a relief. now it is only a quetsion of trials and learning.
The machine seems to be perfect.
 thanks for all.
Anam funny: The max current that my ESCs share is 4-6 Amps and at these currents they are cool
pl watch the short video

Nice and stable Thumbs Up

The trick to landing these, and even regular helis is to try to make them hover at a small height, and let gravity do its thing gradually.  Do NOT bring down the throttle stick lower than 1 or 2 clicks from the position needed to make it hover at a constant height.

Thanks Sundaramvelar. I missed your comments, sorry. The machine seems to be very stable, though i am still to learn to fly it with confidence,
thanks a lot
ashta



Ashta Ji very interesting thread fabulous.  Clap  Clap  Clap 

I am following this intently. Eagerly awaiting more details on servos setup and mixing, gyros setup, throttle mixing and reference details.

Please do post the radio/gyro settings you had to tweak.  That would be interesting information to many (especially gyro gain, gyro mode etc) Smiley

Dear Anwar,
I will post them.
Still i think that there is lot of scope to play around. Most of the tweaking i did by trying to fly the copter by passing a string thru the center and watching carefully. ( pl see the video i had posted)
After doing this i have not done any tuning on real flight. I should do that for more fine tuning.
Let me try to recollect.
Mine is Futabs 7C
Swash:
HR3, 120 CCPM
Aeleron= +43
Elevator=-40
Pitch= -100

For the Three Motor Gyros, the Gains are connected together to TH chanel (Ch3).
50% = Neutral
60%= 20% Gain rate mode
70%= 40% Gain rate mode
80%=60% Gain rate mode
90%=80% Gain rate mode
100%=100% Gain rate mode

I kept at aroud 93%

40%= 20% Gain Head Hold mode
30%= 40% Gain Head Hold mode
20%=60% Gain Head Hold mode
10%=80% Gain Head Hold mode

Motor Gyros are always in rate mode

For the Yaw Gyro, the gain is thru CH 5. I control it thru Switch A. On power on i keep it in rate mode and while flying i put it in Head hold mode.
Sw pos 1= +100
Sw pos2= -100
Pos 1 i keep at 50
Po 2 i keep at -39
The Pitch curve is
30.5
45
58
72
100

This is my last settings

So your throttle channel is reversed, it seems.  Can you post reversal information too for all channels.
