Default How to use a 2 wire EDF

I have been pulled in kicking and screaming after 80 years of modeling into the wonderful world of E flight, I was given a 60 mm EDF. if I hook it up to a directly to a small 3 cell LiPo it winds right up but when hooked up to a new GWS 1CS-480Li ESC the radio works the ESC lights up put he fan does not run, I programmed the throttle but no luck any help would be greatly appreciated Mike

If you are using Futaba transmitter, it should have it's throttle reversed.

Do servos work ok?

BTW Mike why not go brushless? Higher efficiency, lower mass, less wear and tear, more choices, cheaper.

Vriendelijke groeten en wees voorzichtig, Ron

('UBEC' is a propriatery brand name, no information in the name. I prefer LBEC, linear, and switching SBEC, switching, gives more info.)


How many servos will you be using, what battery voltage?

Don't use more than two-three(?) servos in combination with linear LBEC on 4s or more.
The higher the power-pack voltage, the fewer servos a non-switching = linear BEC can handle. Switching BEC's hardly have this restriction.
The higher the battery voltage, the hotter a linear BEC will get, for a given current/load/servos.
Or, in other words ...
The higher the battery voltage, the lower the current a linear BEC can supply.

In depth:
