Exscuse my ignarance...what is a ubec? niversal Battery Elimination Circuit. It provides power to the Rx, which in turn passes power (as dictated to it by you) to the servos. |

Quote from the site: "Input: 523V" Argh! I think they are missing a "-"  Looks ok though. |

One thing that you may not be aware of if fitting a UBEC, remove the red wire pin from the ESC on the connector that goes into the Rx. This will negate the two devices attempting to supply 5V to the Rx.
It's normal practice just to push the pin out of the connector, bend it back and then use insulation tape to strap it to the body of the 3 wires. You can then always re-enable this if the ESC is used in a different application.

Yes, that is one thing I'd read about. I was going to purchase a or fabricate a short jumper and simply exclude the wire completely, thus leaving the UBEC unchanged.

Well, I just ordered it, I'll let y'all know how it works out along with my other upgrades.

Exscuse my ignarance...what is a ubec? Which may explain some of your problems. Read up, especially if you use Spektrum. ALL NEWBIES TO SPEKTRUM NEED TO READ THIS AND SOME OF THE MAIN LINKS! TO NOT KNOW THIS INFORMATION IS TO RISK PLANE CRASH AND RUIN YOUR CONVERTED CUB! Spektrum brown out-servos and modssupercubclub.proboards.com/index.cgi?board=rg&action=display&thread=1858 |

I think the FlySky are more resistant to Brown Out. OTOH, if you push it, anything can fail.
FWIW if you had gone a notch up to a HW 40A ESC w/3A switching BEC you could have skipped the UBEC.
Switching BEC don't make heat to bring the voltage down, They are more efficient, more effective, and generally more expensive. Most of the time they don't show up until 30-40A ESC.
If you didn't buy the programming card....you should have. Stick programming sucks. It's good to set the LVC higher on these. Sometimes you want to play with the timing, although I doubt it with this motor.

I will keep that in mind regarding switching BEC next time I buy.
I DID buy the programming card, it was highly recommended.

Is this what happened to my squall?brown out? The fan cut no power.......then crash! Would a ubec have saved my squall? Possibly. What ESC was it using, what RX, how many of what make/type servos? Although Spektrum were the first manufacturer that were widely reported to suffer from this, other makes have the potential to also be afflicted. I believe it's not as prevalent on much of the other trusted manufacturers as their RX's tend to continue to operate at lower voltages. Who knows how well the Chinese clone market of RXs handle a voltage dip? |
