Default AXI2208-34 SHUTS DOWN

I think this feature is to let you know the battery's getting low. after moving the throttle down and back it goes again. thats nice but not when the planes pointed straight up 5 feet off the ground, how do I override this?

WELL, the speed control really cuts it off unless you ar using kokams and trust me if you load the motor up they shut off with kokams. DOnat ask me why but it happens to a lot of people at my flyins!!! Its really IMo loading up the motor too much...there is a way to stop it but i dotn remember. Be careful doig that becuase you have to have the "feel" of when the battery is getting low!!!

WHAT SPEED CONTROL DO YOU HAVE? I HAVE A PHOENIX 25 AND IT CAN BE PROGRAMMED WHEN TO SHUT OFF AT A CERTAIN VOLT LEVEL.

Clearly, you need a better battery pack. That Jeti probably has a low-voltage cut-off at ~5v, and if you are getting that low from overloading or flying too long, you are jeopardizing your batteries (especially if you are using Lipoly - and if you are, you MUST get an ESC with programmable LVC [Castle Creations Phoenix 10]). Exactly what battery pack do you have? That 2208/34 should be pulling no more than 8A if you have it correctly propped, but are your batteries rated to produce as much as that?

Cheers, Phil

Dr Kiwi nailed this one. I had a simular problem with my shockflyer setup. I ordered the Axi 2208/34 and tried using a thunder power 2 cell battery with it. I think it was a 760mah or so. I couldn't get much out of it before it cut out even with my pheonix 10 set to 2 cell low voltage cutoff. So I said, hey I'm going to use a 3cell. So I bought a thunder power 3cell 730mah, set my pheonix 10 to 3 cell and experienced the same problem. The problem is that these batteries only have like a 6C rating meaning they will only produce 6 times the listed amp hour rating in this case 4.3A. Pull any more current than that and the voltage starts to drop considerably. Then the low voltage cut off kicks in like it's supposed to and that's it your done.

So I bought a Tanic 3cell 850mah 10C rated battery. This thing will provide a constant 8.5amps if needed. Needless to say I haven't had any problems since, and have a ton of straight up power. It prop hangs about 1/2 throttle.

If you think this battery is a little heavy for the shockflyer, your right! It does seem a litte heavy when gliding in with no power.

I went to the Kokam site and it looks like they have high output 20C batteries now. A smaller one of those might be the hot ticket.

I am going to keep what I have cause I'm tired of buying batteries.[]
