Hi,
I have been struggling for a week or so trying hit and miss to set up my Swift for AP work. Here is my current setup:
Swift 16 using CNC head, 550 carbon blades
Phoenix 85HV (all default settings for programming)
Z30A-800, 9T pinion
TrueRC 8S1P (10C) 4000mah
Futaba 7C
Askman Medium Heli PAN AP system
Canon A640
Normal Mode
TH CRV: 0,30,60,70,80
PI CRV: 25,37,50,71,92 (gives me -4,+10.5)
I only fly the AP setup in normal mode at this point (not idle up).
Here are the main weight break downs:
AUW Full system: 157.05oz, 9.81 lbs
AUW Heli/battery:102.55oz/6.4lbs
AUW Camera/mount: 54.5oz/3.4lbs
I seem to be getting around 9+ minutes of flight with the full setup depending on where my throttle curve is set. At the end of almost every flight the motor is cutting out (NOT GOOD). When I land the ESC is blinking 4 flashes followed by a pause. I looked at the instructions that came with the Phoenix and I do not see any explanation of flashes after a flight. The ESC is barely even warm, the Z30A-800 is hot and the battery is hot. I do not have a temperature probe so I cannot say exactly what the temp is. I can hold them but they are hot to hold. I am consistently replacing 3600+ mah back in the batteries when recharging. This leaves 10% or less in the battery which I know I cannot keep doing. My biggest issue at this point is not necessarily the run time, I know 9+ minutes is good for this much weight. The issue I guess is why is the motor/ESC cutting out? Is it a low voltage cut-off? Is is the motor/battery getting too hot as a result of amp draw? I do not know and am not sure how to determine this. I know I can reduce the amount of time I am flying, but based on what I have seen others posting I have been expecting to get flights in the 10 minute range without the cut-out issues. I cannot risk another auto-rotate from 50 feet with a full AP payload. Hogster on RCGroups calculated I am probably pulling around 21A (I think I may be pulling more than that).
thank you,
Mark
