I received my new APM2.5 like 3 days ago.
Some background about this build... I am using the frame I was using before for my ELEV-8 quadcopter which included a Hoverfy SPORT flight controller.
The manual for the hoverfly said that I had to calibrate the ESC's to use Ni-xx mode as battery type instead of Li-xx mode
I am using Turnigy Plush 30A ESC's.
I wonder if I have to change the battery type to Li-xx for the APM2.5 or if it's ok to keep using it on Ni-xx battery type. (I already modified to use batt type Li-xx, but I am not sure if this could be one of the reasons why I am still not able to arm the motors)
Thank you! :)
Leave the esc set for Ni but would not effect the arming.....try ruder to left......make sure the right mode is set in the transmitter
I will put it back to Ni.
Also tried the automatic ESC calibration and all 4 motors where moving correctly.
Who knows what I am missing, going to keep looking what I am doing wrong here.
And try re-calibrating your radio
I had the same problem it took me 2 day and Chris's help to figure out.
I have a TG 9x radio mode 2 but when you set up a new model it is defaulted to mode 1 every thing looked ok even calibrating the radio look the same as my other units...could not understand why it would not arm. Checked the setting and changed all worked I felt real smart......
yeah, I think it could be something with the radio.
Mine is Futaba 7C
I just calibrated the radio and this is the information collected (see screenshot)
Do you see anything abnormal?
That looks fine just like mine did
do you have any of the limits set that could be it also
Mode 1 is thro on right
Mode 2 is thro on left
I have also had to reverse the rudder because it arm when I went to the left instead of right
Mine is mode 2.
It was arming the motors moving the rudder to the left instead of right :)
Does this mean that if I go fly... the yaw is inverted? Or this is just affecting the arm/desarm process?
Yes it will be revers, fix in radio or apm
Also make sure the props are spinning the right direction it is not the same as for the hoverfly......
I just tried the hoverfly again and I still can not fly it at all. I can fly just about any thing else with no problems. I wonder if I have a bad board
I am a big fan of the propeller chip.....I tried twice
My ELEV 8 flies nice with an APM2 and stock pids
Alt Hold, waypoints all work fine
I have also had poor luck with the Hoverfly. It seems to be just a stabilization augmentation system. Sometimes I can fly but very erratic. I use the prop chip a lot an many applications, but I think here it falls short. I have consigned my hoverfly sport to the recycle bin and will fit the ELEV-8 with the APM2 as soon as I see the demo at Maker Faire in NYC tomorrow !
I think I can't call mine ELEV8 anymore.
It's more like a Frankenstein now :)
In fact, I built 2 frames (45cm from motor to motor) and mounted the Hoverfly on the other one and both fly, but I still need to tweak the APM because when I go full throttle, it wobbles a bit and the yaw is a bit aggressive.
Here's a pic of the APM quad on the test "bench"
I am planning to convert an ELEV-8 frame to APM2.5. I found the Hoverfly SPORT board pretty useless. I am very interested in how your conversion goes and if you can achieve auto level and altitude hold. Are you also planning to have it follow GPS setpoints ?
Look forward to foolowing your progress.
I am planning to mount everything I can :)
Right now, I haven't configured it to use the GPS (ublox gps) or autolevel.
Once I find the right PID's for everything, will go and set up all the other modes.
After testing both the Hoverfly SPORT and the APM2.5, I feel like if they are different flavors of flying behavior.
The HF Sport is definitely more "manual" so, if you learn to fly the HF Sport, the APM will be a piece of cake (once you find the right PID values).
Let me know if you are having any problems, to see if I can help. :)
