motor cutting out

I could use some expert help. Let me give details first...aquastar t20 motor, aquastar 200a esc, castle 10a bec, spektrum dx5 with ar610 receiver, 2 traxxas 5000mah, 25c 11.1 volt lipos. I have power to receiver, power to esc. At neutral theesc beeps once and is ready to go. When I give throttle, it runs fine for about 3 to 5 seconds, then cuts out...I can go back to neutral and get it to run again until it cuts out again in 3 seconds. Motor and esc never get above room temp even after repeating this several times. Any ideas? Suggestions? Hopefully its just a simple fix and I am being boneheaded! Thank you!

I don't know what is causing it, but have you calibrated your remote throttle to the ESC?

Hi Chuck,

How are you using this motor, in Y or D wind?
How are the two Lipo's connected, in series, or in parallel?
What boat are you powering and what size and pitch prop is used?

Depending on thew load and the configuration, it's very well possible the 25C packs can't deliver the current for the motor, which causes the ESC to shut down.

We need more info to make an accurate guestimate...

Regards, Jan.

Not quite sure how to properly calibrate tx to esc. As for your questions, Jan, batteries are in line (for higher power) and the motor is not hooked up to drive shaft. Motor is rigged for 730kv. Btw... boat is 48", 20 lbs. ! But I dont think these are in play yet because of drive not hooked up.
