New version of Leo Motors?

[JohnZ]

So what's so different between the Leopard X2 motors and the other older ones?
It doesn't appear they are all that much different.

They are X2 Better!!

From the looks of the information on their website:

- End Bells have more venting
- Only offered currently in 2 configurations for the 3674 X2: 2650kv and 1900kv
- X2 2650kv good for 3s (12.6V) and pulls max 120 amps ***advertised*** current version good for 22V and and pulls max 110 amps ***advertised*** (both 2.5 D-winds)
- X2 1900kv good for 6s (25.2V) and pulls max 85 amps ***advertised*** current version good for 31V and and pulls max 78 amps ***advertised*** (both 3.5 D-winds)

So they are technically worse according to what is ***advertised***

It could be that experience has shown that the original specs were a bit too optimistic....

Either that or these are capable of "more" as far as power is concerned.

- Only offered currently in 2 configurations for the 3674 X2: 2650kv and 1900kv

- both 2650kv & 2.5 D-winds
- X2 good for 3s (12.6V) and pulls max 120 amps as advertised = 1500 Max Watts
- Current version good for 22V and pulls max 110 amps as advertised= 2400 Max Watts

-both 1900kv 3.5 D-winds
- X2 good for 6s (25.2V) and pulls max 85 amps as advertised = 2150 Max Watts
- Current version good for 31V and pulls max 78 amps as advertised = 2400 Max Watts

Something fishy here - A new product called X2, You think would be 2 Times Better NOT less Max Watts.

Just from the specs the X2s look better to me, on the 2650kv 120A beats 110A, the watts are irrelevant as 2650KV is inappropriate for 6s even if the motor is capable. The same is true for the 1900KV versions, I sure as hell wouldn't be running one on 31v for near 60,000rpm so more power at a more suitable voltage sounds like a much better prospect.

Lets take the 2650kv Motor
The X2 say's it is only good for a MAX of 3S -12.6V at 120A = 1500 Watts max. (2.01 horsepower)

Current version good for 22V at 110 A = 2400 Max Watts (3.22 horsepower)
So you could run this on 4S pulling 143A and still be at the 2400W max. (3.22 horsepower)

So tell me why I would want to buy the X2 motor that only has a 3S max. with Less Max Watts??
Or even in the same 3S -12.6V setup, I can now run a larger or higher Pitch prop at 190A = 2400W (3.22 horsepower)


Lets take the 1900kv Motor
The X2 good for 6s - 25.2V at 85 amps as advertised = 2150 Max Watts (2.88 horsepower)

Current version good for up to 31V at 78 A = 2400 Max Watts (3.22 horsepower)
So if I run it on 6S-25.2V at 95A =2400Watts (3.22 horsepower)

So I think the current motor even in the same setup would be a better bet, seeing that you are not abusing it as much with a 2400W Max.

To my knowledge, that's not how electrons work. A particular material can only handle so much amperage at a give voltage. You can't just up the current "prediction" because you have a lower voltage. In fact, electrons flow easier at higher voltages than they do at lower voltages which further backs up my counter "argument" if you want to call it that. If I am correct, your entire statement is invalid.

[TRUCKPULL]

A particular material can only handle so much amperage at a give voltage.

I completely with your statement "A particular material can only handle so much amperage at a give voltage."

Amperage times Voltage = Watts

10V X 10A = 100W
100V X 1 A = 100W

If a motor is rated at 30V at 100A = 3000W
If you only put in 20V you can now use 150A = 3000W

And this matches your statement above.

I,ve been testing the X2 3660 2380kv on my rigger and can say it works great on 4S...a good motor for P limited. Gill
