I had a Dominator 450L sitting around and I decided to install my old APM 2.6 so that I can continue to learn traditional helicopters with out jeopardizing my 700 Trex with a PixHawk. So I have had success setting up traditional helicopters. This is my 700 Trex.
It is a Dominator 700L with a PixHawk designed for mapping and S&R. It currently has 40-50hrs on it and running strong. I have had a few incidents with it that were complete newbie mistakes. So this system has recently been donated to NMSU, UAS Flight Test Center for continued R&D and Flight operations.
With that, to the subject at hand. I have built my Dominator 450L and installed the APM 2.6. I have leveled the head and completed all the ground setup. I noticed that when I arm the APM and start the motor with channel 8 all works well until I switch to Alt Hold and Loiter. I no longer have control of Pitch, Roll, and Yaw. It just goes to full negative collective even if I give it full positive on the controller. This doesn't seem right and I have never ran into this situation with my PixHawk. Has anyone else run into this with the APM 2.6, and if so what is the corrective action on this.
Thanks in advance....
