I know the site says n/a for 6.0v however as it has been in the past Futaba stated the 9252 was not goodn on 6V either and look at hoe many people are running them on 6V regulated.

Anyhow I have a BEC I am interested in trying.

It is 5.6 voltsa constant, and these particular ones apparently really are awesome and deliver consistent power with no fall off I am told. Only I am thinking,,, I have a 611/9256 on every heli I have, now if this output were a steady 6V I would be fine just using a stepdown which would bring the output to 5.3 to the tr servo, but will the tr servo handle 5.6 without issues is the question? And since I am in some ways impared to know,,, with a stepdown "duralite" it would bring the voltage for the tr servo down to 4.9 volts correct? From what I understand Duralite stepdown reduce the voltage by .7 volts, or am I misunderstaning it and that it actually control the voltage to 5.3 no matter what the input voltage is??

Thanks if you can help :wink:

The step down steps the voltage down .7 volt from the voltage being supplied to it.
6 volts = 5.3 volts from step down
5.3 volts = 4.6 volts from step down
5.6 volts = 4.9 volts from step down

The 9256 should handle 5.6 volts regulated with no problems. The 9251 has no problem with it and is basically same servo.

I just found out this BEC apparently falls off voltage so I will not be interested in that. Now that being said I sure hope Koolflight one day wakes up and makes a 45 in / 6 V out UBEC. Thanks for response none the less! :D
