Hello Dear Friends
I've build an Hexacopter based on Tarot 680Pro frame.
The problem Is that It doesn't take off at all (80% throttle until it actually start trying to)
I've calibrate the Remote (via Mission Planner) and the Esc's and It looks like It doesn't have sufficient power.
The Electronics Specs of it are:
6* Afro ESC 30Amp Esc's (SimonK firmware) - I didn't try to reconfigure it
HML 650 Carbon Fiber Folding Legs
APM 2.6 Firmware 3.2 Controller
Some lite FPV+Telemetry+MinimOSD+3 AA Battries.
Total weight about 2.8Kg
What Can be the problem for it can't lift itself at all?!?
Thank you very much
Best Regards
Yochai

Hello
eCalc has gave me "Your Setup is unrealistic and way out of Limits!" (I didn't found my motor and pick Turnigy Multistar 350kv instead)
Yes a smaller motor (700kv) gave me realistic result but the motors is the last thing I'll want to change (cost and installation time)
BTW this Hexa is for a Delivery testing so I'll put 2Kg-4Kg load on it most of the time!!!
What should I change in order to have this Hexa fly and hover in 60%-70% trorrle?
*Flip 3 arms + 15 inch props? (what pitch is the best)
*Change Battery to 6S?
*Change Esc's to 40A-50A?
Thank you all you are helping me allot to clear the duets away
Try to go up in stabilize and then, when you are at 5 meters switch to althold. This should work. Furthermore, take a look at the throttle_mid parameter and the tutorial at the arducopter-wiki how to set this up as best.
In Stabilize it looks like the worst problem.
In AltHold it actually started to take of for 2maters for 5 sec (but than I land it since the wind was very strong today.
What can we conclude from all of that?
Your blades and battery may be undersized for the KV of the motor.
That motor can go to a 6s battery and drive blades around 17-18 inches.
You might try larger blades first.
Dear Robert
Thank you for your answer.
Currently my Tarot680 frame will only allow bigger blades if I'll turn around 3 arms 180 degrees.
So I'll have 3 motors up and 3 motors down (the blades should be all up of course)
The blades will not be level and I'll hope to find a blades that I can install upside down on this big motor surface.
If so. would some one can recommend me on this setup?
What are the pros & cons?
Thank you all
