Leopard Hobby 4-Pole CC/Neu Clones

[Brushless55]

I only have a few coming in for testing. I rather test instead of customers being beta testers.

Someone said they are expensive. Anyone seen a retail cost yet?

Any word Steven of when your getting some motors?

I see no water cooling, how did the temps read?

I put an Eagle Tree system on the boat when Mark ran it. I believe the motor temp was around 110. If you search the site under a thread posted by MarkF I believe you can even find a video I posted of the Eagle Tree data playpack on my laptop from the run with the Leopard 4075.

There seems to be lots of interest and threads on the new Genesis. Here is some additional information that you may find of interest:

1. The stock Genesis set up by HobbyKing uses a 3674 2-pole brushless motor with Seaking 90A ESC turning a P1.4x 38mm Dia nylon prop. Stock speed is 60 kph or 37 MPH
2. The upgraded set up consists of a Leopard LB4074 4-pole brushless motor and Seaking 120A ESC turning a metal prop P1.4 x 40 mm dia. Stock speed with this set up is 75 kph or 47 MPH
3. The ultimate set up consists of two Leopard LB4074 4-pole brushless motors and Seaking 120A or upgrade to Seaking 180A ESC’s. Prop size is experimental. Estimated speed in excess of 60 MPH.

The motor is very efficient however it is easy to use a motor mount with integral water cooling and a factory installed silicon water jacket.

110* that sounds awesome for no cooling
thanks

I think it went up to 113F. You can see the vide3o of the Eagle Tree Data at:

I asked Bill at Eagle Tree about the speed at 75 MPS and not a glitch - He did/could not explain it. Look at the high AMp draw and Watts....almost 3 HP!

So your Hydro did 75mph with the Leopard motor?

Very cool stuff, but I did not see the watts that equals 3hp?

[ray schrauwen]

I see a peak of 1782.2 watts, V x A= W
134 amps x 13.3 = 1782.2 divide by 746 = 2.38 HP

That's what I came up with but he said "almost 3hp"
so my math is correct with yours

It appears that HK has a ARTR hull with the Leopard 2200kv motor installed. Not a bad looker either for the bux. http://www.hobbycity.com/hobbycity/s...)_Plug-n-Drive

Yah, someone on OSE has that boat and has taken out the motor to put something else in it...

How tight is this motor compared to a Neu, I mean the way the shaft turns?

What does it "feel" like?

[MarkF]

The motor has a lot of cog and is hard to turn. That doesn't means anything when comparring motors though. There's also a reason why this motor cost less than half of a Neu. Only time will tell how well these motors hold up over time. I think this motor is fine for sport boaters looking for a cheap alternative and not wanting the best.

Thank you, nice info.

I have bought really cheasy 4 pole chinese motors before that had cogg, not much and were woefully inefficient. It was a $20 motor... I use it to test esc's now.

Any news on the Big 5692 series if they are selling them and were ? I sent them a email but did not get a reply on it i want to test 2 of them in my next project , MHZ Drambui on Ice 53"catamaran.

[Brushless55]

That looks like a fun project!
