How'd you guys order from the RC-fans site? I'm guessing that's where you got the 5692 for 100$ or so, but it's only wholesale?

after 15batts all the leopards and hobbywing escs works perfect ;)

the leopards are incredible cold ...... lower hot than the xerun 4274 :)

100% recommended

Someone. Please. I've asked several times now, but how do you order from the wholesale site? There isn't even a pricetag available.

I have break the rule and buy one leopard hobby brushless motor (4074 1400Kv in my 6S buggy).
It works perfectly, but the quality does not come even close to the Castle motors : the wires are in fact the windings, the can does not have cooling fins, which make it heat more than the Castle, the rotor looks very messy with its strange kevlar...
But with an additionnal heatsink, it runs as cool as my Castle motors, and the efficiency is the same, moreover the bearing are as big as Castle one's, so for the price, it's a good choice if you want a small Kv motor with high voltage setup. I will try some tuning, like put Castle rotor in and see what happen...
I just wait that Castle build its 1515 1.5Y 1466Kv motor to replace it !

bud thanks for the update.. any chance of some vids of these running? and temps being recorded after your runs and break down of your gearing etc and weight of the rcs?

Sorry about asking for a lot, but i just want to get a better idea...

CHEERS

i am very tempted to try one of the leopard 1000kv motors but i am struggling to believe that when the can is smaller than a castle 1520 1600kv motor, can it really deal with the stress of running 10s???? Maybe it can? But i think i will give it a go and test it at some point...

4082/2.5y for 9s ... 4082/3y for 10s ... rpm don't over 50000 !

Part of the difference in diameter is the fins of the CC motor. The rest, who knows wihout internal dimensions on both. Either way the difference in size is too close to have much of an impact. Lack of fins, construction and materials differences would have a bigger impact.

The 4082 is equivalent to a Castle 1518 I think...

Jahay · 05.05.2011, 08:33 AM

i was reading some descriptions, but i am unsure as to what is accurate!

I was looking at the Leopard 4082 1000kv or 1250kv (42x82mm can)
http://www.offshoreelectrics.com/pro...o-4082&cat=148

But it says that they should only run 25,000-35,000 rpm???

It is a little low right? Because on 9s a 1250kv motor is spinning at 41,000rpm... That seems acceptable right?

Those RPM suggestions are from OSE (off shore electrics), and seem to just be a very general guide line...

In my experience a tame setup is 25-30k, a performance setup is 30-40k, and a screaming setup is 40k and up. I think the higher the RPM the motor peaks at the more aggressive the acceleration is getting to that RPM. I've settled in at around 38-40k for the best compromise of power and run time for most of my rigs :-)

Jahay · 05.07.2011, 05:08 AM

considering i already have 9s worth or lipos... i would most prob go for the 4082/2.5y for 9s
Im just shocked that the size of the can is of that of the 1518!!! Smaller than a 1520! i dont know how well it will be able to cope with my heavier truck... only one way to find out i guess haha

Just out of curiousity... if a motor fails and implodes, would and esc blow too?
