Question about Phoenix 25

[trailblazer]

What is the recommended voltage and mAh for the Brushless ESC mentioned above without doing any programming?

AND

If any programming is needed, what programming feature is used? What option must be chosen for each option?

(preferable to give recommended voltage and mAh for each option)

Your questions are not specific enuf for anyone to give u an answer, need to know - for what type of aircraft- plank, rotating wing, hotliner etc, batt - type, how many cells, motor what type outrunner, inrunner, how many poles.

Cheers

Em Up to how much mah u want to use n i think voltage limited to 10cells or 3s lipos??? for BEC??

What you need is CC25 user manual

i was with him when we discussed this issue. To give jerome a hand, i shall rephrase for him.

what he is asking is that how can he restrict the amps drawn by the ESC. coz the battery he is using is rated at 12C. is there any settings on the programming of the ESC to be able to do this?

i also not sure if what i am saying is making sense. what i know is that if the batt is over discharge, it will become damaged and dangerous to use

pls advise

thanks

The amount of current is depended on type of motor and the number of cells used. Different configuration would give different current consumption based on same amount of throttle throw on the transmitter. ESC has nothing to do with it. It simply works according to the duration of the pulse width of the signal. That is why we need to know what would be the max. current on full throttle for a particular configuration, then select a suitable ESC to go with it.


But there is a way to go around with it. To prevent over discharge on the batteries, you can limit the throttle upper limit through programming setting; tone down the limit to less than 100% (by default) and work it out whatever work best for you provided you own one of the digital transmitter. Or change to higher capacity batteries if the ESC can take the max. current load.

Ar so des ka, let see I can help here.

Assuming the batt is 1700 12c rating, 20.4 amps cont draw, CC25 = 25 amps, in absolute term cannot protect the batt. In pratical term - this is a possible solution- set program 2 to sensitive cut-off, select a prop via testing and measure max amps draw at WOT. use a prop with max static amp draw at WOT <= 25 amps. Actual flying amps will be lower. Only on verticals climbs the amp draw will come close or equal to WOT.

i also not sure if what i am saying is making sense. what i know is that if the batt is over discharge, it will become damaged and dangerous to use

pls advise

In programe 1, make sure the setting is correct, the danger of over-discharge will not happen. The esc will cutoff the supply to the motor.

U can limit current using Castle Creation ESC to some extend...just put your timing setting to the lower settings....

Option 3 I think....Low Timing, Normal and Advanced....not too sure how much that might help...

I think the question is that he does not have the PHX-Link software to program the ESC, so he is asking about the default.

He should refer to the manual for the default values.

Unless CC had remove the conventional programming tools, one can still programe it w/o the USB link.
