After looking at the various setups I purchased a phoenix 45 esc so I could run a 4s lipo pack with a scorpion 3014-16 motor. I also picked up a couple of Rhine 4s2350 battery packs. After putting it all together, I can't get the motor to arm. The esc beeps, but it does not beep when throttle is pulled back like it is supposed to. I tried putting on a 3S pack and it arms fine. What am I missing here? Is there something not shown in the setups for you guys using the phoenix 45 with a 4S pack? (like an external BEC maybe?)

Are you using a timer or RC gear?

You need to set the paramaters in the ESC to tell it what pack/voltage you are using - it may be that?

Hi jj

1. What Wynn said

2. also, is the 4S pack charged - are you sure of what the voltage is (and no bad cells)

3. Are you using the Castle Link? if so, try printing out the settings and then copy them here as a text file - maybe someone wil see something in your settings...

After my initial post I went back and reread the instructions and noted the ESC needed no set up if I didn't want to reprogram anything, so I just hooked up my Igor timer and plugged it in and it spooled right up. After a minute of so the motor would cut out, restart, cut out, etc. I'm wondering if the 4S pack is too much current for that motor? I have ordered Will Hubin's new programer and will give it a try as it soon as it arrives.

OK, can you check & see where the low voltage cut-off is set?

The start-stop sounds like the battery draw is taking the battery voltage below the low voltage cut-off, and when the load goes off the battery voltage recovers...

I have overloaded motors int he past, they did not behave like yours, but they DID give up the magic smoke (ugh)

Hello Jim,
It sounds like the RC set you are using does not have the low-throttle end-point adjustment or trim set properly.
The ESC (any of them) will not arm until the ESC "sees" a low throttle position. This low throttle position is ideally 1000 micro-seconds pulse width, where ideally full throttle is 2000 microseconds wide.
In reality, most ESCs interpret anything below 1100 as idle and anything above 1900 as full.
If the radio has AATVs or end-point adjustments, set them to 100% and set the trim to full low.
best Regatrds,
Dean

Dean. what the hell is a regatrd?

it seems to ryme with megatrd, no sh@T............

I think it's short for "Regards from a Retard"

If it was a problem with the radio/throttle endpoints/direction, it wouldn't work with three cells either (OP said worked OK with 3, wouldn't work with 4 cell). The description of the on/off/on sounds like the LVC is not set correctly - though it doesn't sound quite like one would expect it to act in the 'default' settings mode either nor does it explain the failure to arm. Best thing to do would be to printout the CastleLink settings and post them here --

I'll have to pick up the cord that allows me to plug esc into computer before I can post any info. I did get the flight manager system from Will H. today. I am not exactly technology literate, but I managed to program two timers in about 2 minutes. I don't know how it could get any easier. I ran a test run on first timer, using phoenix high rpm set to around 9600 rpm and it was taching at 9500, delay time and run time were right on the money. I tried a 5 minute run on the second timer, set at same RPM, it was only taching at about 8600 rpm (different battery but fully charged as well) Shouldn't be a problem as I can adjust rpm up till I get what I want. It did run out of poop and shut off at 4 minutes. I'm charging the battery now to see how many mah's I took out of battery. (4S2350). If I can just get the right motor/battery/prop combo now I will be set. Thanks Will for a great product!!

Hi Jim,
Oh yes, static running with the same prop and RPM as you intend to fly with often consumes 1-1/2 + times the current you would expect in the air. That explains the early battery voltage cutoff. This is generally not good for battery longevity.
Hope that helps,
Dean P.
