I am looking to power this plane: Fun Foam SU26-25 inch (http://www.3dhobbyshop.com/detail.aspx?ID=315)
I already have a CC Phoenix 10, I can also throw a cool runnings 12 on it, and I wanted to use my existing TP3S480PL batteries.
Here is the motor that was suggested to me: Feigao (http://www.3dhobbyshop.com/detail.aspx?ID=14)
Propeller: Volts (V): Amps (A): Thrust (g/oz):
EP-1047 9.6V 3.3A 346g / 12.1 oz
EP-1047 11.1V 4.1A 440g / 15.4 oz
EP-1080 9.6V 4.4A 366g / 12.8 oz
EP-1080 11.1V 5.6A 457g / 16 oz
EP-1147 8.4V 3.1A 326g / 11.4 oz
EP-1147 9.6V 4A 426g / 14.9 oz
EP-1147 11.1V 5.1A 554g / 19.4 oz
EP-1180 8.4V 4.3A 346g / 12.1 oz
EP-1180 9.6V 5.5A 434g / 15.2 oz
EP-1180 11.1V 6.4A 517g / 18.1 oz
EP-1280 7.2V 3.8A 360g / 12.6 oz
EP-1280 8.4V 4.5A 414g / 14.5 oz
EP-1280 9.6V 5.6A 520g / 18.2 oz
Does anyone have experience with these motors? All I have ever run is BL Hacker..so I know nada about the geared setups. I just heard it will have great power at a lower AMP draw for my 3s480pl batteries.
Any insight would be greatly appreciated.

I've run three of them. The GWS "B" drive worked best for me with a 10x4.7 prop and 3s battery. The TP 480 will do fine with it, and it will easily deliver enough oomph to handle hover, etc.

Flight times will be impressive with reasonable throttle management.

There is one trick: the wires tend to break way easy where they come out of the can; any old light crash will do the job (and 3D _means_ crash).

There are various workarounds, but I've had good luck by first sealing all the wires together with some good heatshrink, then gooping the whole area of the exit hole with a generous gob of epoxy. Make sure you don't get any of it where you want the heat sink (yes, you will definitely want a heat sink).

So - how do I fix the two broken wires that snapped right at the edge of the motor casing ? :(

Keven. ;)

Well it has come down between this motor and a CustomCDR single, not sure which is most efficient. I know the CDR is probably allot stronger as far as durability goes.

Ken,

I have yet to see a custom CD motor as efficient as the geared Feigao. That said, I mostly fly custom CD motors, mostly that I make myself. Efficiency is not the only thing! (I like husssshhhhed motors -- real quiet). The Feigao can be geared to deliver tremendous power.

Keven,

If you find a way to fix them, let me know. I have two (2!) dead cans myself. I think it would take a miracle worker with some solder.

Are you talking about the 130 series (20mm)? I know the 120 series (12mm IPS size) has problems with wires breaking, but I can't imagine that these ones on the 130's are prone to breaking.

Cheers, Phil

I was talking about the IPS sized Feigaos...

I've done as Dave suggested with my two Feigao BLIPS in the EDF's this afternoon ! ;)
The three wires are now shrunk together with yellow tubing, and 'encased' in a glob of glue...

The one with broken wires ( fitted into a B ratio gearbox ) will be pulled to bits in the interests of science - to see if I can solder new wires to something ! :eek:

Keven. :)

Thanks for the motor Phil, I will try to be nice to it:cool:...may it survive my flying:p

Phil,

Like Kev said, the topic was the 12mm motors. As far as I know the larger cans have no such problem at all.

I was puzzled 'cos Ken's initial post (#1) was about the 130 series (specifically the 1308441S) - I just wondered why the 12084xx 12mm IPS size came into the discussion at all? But since a fix for them was suggested I guess the thread has served two purposes!

Holy cow, Phil! You're right! Ooops ...

Hey guy's, i too have Feigo ips problems. Motor cut out on me in flight and upon checking found broken wire. Repaired it with splice.Motor ran intermitently so moving wires around found another broken and fixed same.
Motor runs intermitently. At start up it jumps and jerks etc. Sometimes runs ok, then shut it off and it won't start.
Big Question, can these little motors be rewound?

crash,

The short and unhappy answer is not really. You can pull the can apart fairly easily and look in there. Gulp! Not a pretty sight. I've managed to nurse one along for a while now (after having a similar experience to yours on two others) but I won't get another. The slightly more expensive Medusa is reputed to solve all these problems and run better.

Thanks Tim, but how does the can come apart?
Do i have to pry it?
Does it unscrew from the front?

crash, this is one of those times when I'm on the road and my motor is at home. I _think_ it's the front that comes off, and I'm trying to remember how but can't picture it in my head. Perry @ aeromicro told me the trick, so you might shoot him an email. I think it's info@aeromicro.com

If you haven't come across the answer (or nobody has piped up before I get home) I'll see if I can check my notes -- or the motor -- once I'm there.

Thanks for the rep, Tim
I have repaired wires on the outside and have the motor working but i still may have to rewind this motor some day.
