Dear all, I've built an hexacopter with APM1, during my first flight I've realized the hexa was going backward, even if there were no wind at all, what could be? (I've done the level procedure)
Second issue, I've uploaded the latest firmware and had some problems in setting up the parameters...really much different from the one I had saved before.
How can I find the recomended parameters list for hexa with firmware 2.6?
As last, when giving throttle (50%), I hear a strange noise coming from one propeller/Motor, looks to me as a kind of cavitation noise...I changed the propeller thinking it was damaged...but it is still the same.
Maybe you mounted one prop upside down. Printing must be on the top. Otherise it has only about 40% thrust and makes this noise.
Hi Micheal and Jani, I'm pretty sure the printing is over...but since I've touched some cable it may be I've connected them in wrong way (I mean from esc to motor) I will double check this evening!
Another question, after uploading the latest firmware (2.6 mav 1.0) I have the impression the minimum throttle available was much higher than before. Could it be? How could I re-arrange it to a proper range?
Thanks! I will tell you
Here is a thread about the changed min throttle and how to change it.
I will check it. Tnx
One further question, my hexa has 880 motors and 12x4,5 props.
I will have an additional payload of 800 grams, not including the 2 batteries (turnigy nano 4000 mha each, other 600 grams more or less).
Do you think the hexa could carry all this weight having a reasonable autonomy?
You can calculate it here. Or you can measure the thrust of one motor and multiply it by six. If your thrust is at least 2 or better 3 times higher than your lift off weight, than it is ok.
Hi all, you were right....the motor was spinning in the wrong direction...stupid me...I've tried to fix better the cables since they tend to unplug, expecially during hard landing...and connected back in wrong sequence....
I will have to fly in a windy environment (25-30 km/h) do you have any special suggestion?
Any PID regulation that could improve the hexa stability?
@MIchael, I've already seen the site, really well done and interesting. I will consider the proportion you suggest.
