aveox 1406/2y + L160 ESC+ ecofan pro ?

StefV · Sep 06, 2004, 12:13 PM

One of our club members bought 2 of the following combos a few years back, but never ran them. He is now thinking about putting them in a foam Concorde he has been building. The questions are:
- how many cells and watts can this take?
- are these a good combo? I seem to find mostly references to the HW609 fan with this motor, rather than 90mm fans.
- Should he upgrade to a midi fan rotor?
- If not, what to change to get something nice for minimal extra investment (plenty of money in there already!) ?

One more thing about the motor: we think it is a 1406/2y, but there are no markings on it. He had to turn out the fan to accept it, as it is about 1-2 mm too large in diameter. Am I right in thinking that therefore the motors are from a particular batch of aveox's made for some other application? ("cusinart" seems to come to mind) . If so, do they differ in any way from standard 1406/2y?

TIA,
Stephane

If you had to turn the motor mount then they are 1406 / 2Y SE's. They perform the same as regular versions but are heavier by an ounce or so due to extra metal thickness in the case.

The 1406/2Y and the Midi-Pro are mismatched in my view. I ran a 1409/2Y on 10 and 14 cells with that fan - 40 amps or so on 10 cells. I don't think you'll be able to use any more than 7 or 8 cells on the 1406's. You would be better off with Midi rotors although those are still hot motors for a 90mm fan. For a twin maybe it'll work OK. The Midi rotors will fit those shrouds fine so it isn't an expensive change.

Try 7 and 8 cells and see what the current draw is. I would not run those motors over 40 amps. Various vintages of those motors had magnet issues, they sling magnets when they get too hot or demagnetize.

Chris, thanks for the feedback.

As I can see, running 7-8 cells at no more than 40 amps results in a rather dismal 320 watts per fan max. A Minifan would do better at lower weight I think...

How many watts can you pull out of a 1406/2Y? Would using another fan be a better option to use the motors/ESC to their fullest?

The other option is to change the motors themselves, but the ESC are sensored, that limits the options a lot!
