Here's how the Leopard 4092 looks like. You can see how it compares to the 74mm little brother. I ran these motors in my HPR115 about a month ago, it pushed the cat to 142kmh with a pair of X447 props.

I love watching some HPRs come together!! Especially one the same size as mine. Like to see how everyone sets them up for ideas. I'm hoping these 1518s I have sitting here will work in mine.Catching Air!Comment

I really like the way you set up those seaking 180's... very nicely done.... the added caps and being inline... goes to show those esc's are nice eye candy when installed in a tasteful way.... Great Build!Comment

Thanks JMSCARD. I was very impressed by the strength of the 180s. My last run ended up with a stuck in one of the flexshafts and the motor on this side got extremely hot(so hot that I saw steam when the hatch was opened), the motor reads 110°C, 10AWG wires are too hot to touch, bullet connectors are de-soldered, there must have been a severe over current event. But when I put everything back together, they work again, ESC survived like nothing happened.Comment

Here's a logged GPS data from my EagleTree.
Blue line: throttle level
Green line: GPS speed in km/h
The 2nd pic is a zoom into the first pic. looks like it might have been faster if I hold full throttle for a few more seconds, but at this speed the boat was 100m away in just 2.x seconds....
Also amazing was the accelaration capability. it speeds up 70kph -> 130kph in just 1.5 seconds, that's over 1.1G of acceleration, faster than most Porsche or Ferarri......
