Hello everybody,
First a few words about my copter : after having started with a Phantom, I am currently switching to another Naza equipped copter, but, this time, custom made.
I just got an old copter (1 year old...) that was taking the dust in my neighbour garage, but never completed.
Here is the configuration :
. Frame from HK (roughly 40cm side)
. Turnigy Esc multistar 30A (stock)
. RC timer BC-2836/9 880kv motors
. Rc timer 10x4.5 carbon propellers
. Graupner MX-16 radio connected to naza through 1 cable (SUMO)
. Naza v2
. PMU v2
. Gps
Everything is correctly configured : I receive correct feedback on the Naza assistant of the radio commands (except the failsafe but it is another story)
my problem : as soon as I install the propellers and start flying, the copter is very unstable and cannot be controlled : I am pretty convinced it comes from the thrust control managed by the Naza : Either the command is correct and the ESC/motor don't interpret it correctly, or it comes from the radio.
I tried to calibrate the thrust course of the ESC consistently with the radio but I must admit I am not sure it worked...
Another strange thing I discovered is that the max RPM and responsivness can be obtained when the ESC is directly connected to the RX, but it is much more lazzy when connected to the Naza. When flying, when command set to Idle on ground, the copter has almost enough lift to fly (at least on 2 propellers).
anybody to help me (ESC calibration, incorrect configuration, ...?
thanks in advance !
Franck
