And 2s for training which is what I do for my son (6) - just change from series to parallel adapter

Aw hell, you got me BG. I concede. I skipped over that post.

:lol:

Did that make your day? :lol:

about ESC and EPA. so should the EPA be set to 120%? or 100%?

Of course! Brevity on a Monday is always welcome. :smile:

It should be set to whatever you have it at during ESC calibration.

I always set mine to the max and then calibrate the esc and radio.

I usually set my EPA to 100% during calibration, and then increase it to 105% for operation. This makes sure I get to WOT even if I get a little component value drift on the throttle pot.

ah ok, well i had mine set to 100% so ill try 105% see if i notice a diff, doesnt matter tho, more power then i can use, even with punch set to 40%

turning the epa down is nonsense huh? have you not read my post? all it is doing is limiting your motor speed when running higher voltages, my speedo ran no hotter when i turned it down from 125 to 90, shoot im gonna buy a 6s and leave my gearing the same with the epa at about 70, just to do it:yes:

I don't believe it's nonsense as partial throttle is hard on the ESC. There are reasons why they make different types of ESC's for cars, boats, planes/heli's.
You would be better off gearing down but the EPA is an option, just not the best option.

Higher voltage is always more efficient but you need to have the appropriate wind motor and gearing.
A 5S 4000mAh pack is equivalent to a 4S 5000mAh but the 5S system will run cooler with the appropriate setup
A 6S 3200mAh pack is equivalent to a 4S 5000mAh but the 6S system will run even cooler with the appropriate setup

I do not believe this is true.

The total energy in each of those packs are about the same there for yeah, its roughly true.

Thats OK, you don't have to believe me, just do the math

Granted 6S would actually = 3333.33mAh, but with the extra efficiency, 3200mAh will suffice.

Are you joking?
