HK Osprey + Turnigy 180 + Leopard 4082 + 6S

[Javito50]

Good morning OSE!!

It is my first post in here, i am trying to figure out the best combo for my boat...

Since i bought it last year with OEM combo, the boat just doesnt work...

I am thinking about this combo, turnigy 180 amps + leopard 4082 with 6s

The thing is that i dont know what prop to choose and what KVs... I am really lost here

The size is 1082mm.

I will really appreciate your help!! Thanks

The Osprey is a big boat, A 4082 motor really isnt big enough it not much better than the 4074 motor that normally comes in the Osprey. They have had some good results on this forum using the leopard 5692 - 1340kv on 6s with a T180 esc & x452 prop. But when using this motor you must move the motor foward quite a lot to get the correct shaft angle as it a big diam motor & needs to go foward otherwise you cant get the motor low enough in the hull to align with existing shaft. Martin.

Thank you very much Martin for your answer, just one more thing... I am guessing because of the size of this motor, the OEM motor mount doesnt fit right??? The shaft must be new as well?? (any recommendation for shaft and motor mount??)

Thanks again i really appreciate the help, i m pretty new to boats, all my life with rc cars

Then the problem with a big diameter motor is that your weight goes forward and folks have already had trouble with it running wet from what i can remember.

If you're not looking for HUGE speed, the 4082 1450kv will work on 6s with an x445-x447

[martin]

Obviously everything in the boat needs moving around, this very set up has been done very well & the boat ran at 50mph not bad for a boat of this size. It certainly didnt run wet, your probably thinking of the Vanquish hull that was a bad copy that hat terrible hook in the rear of the hull & ran wet. Theirs a whole section 0n the build & vid of the Osprey by Forescott under the build section.

Heres the vid & build of the Osprey.

If you go for a larger motor, your ESC can handle this on 6s with a decent size prop..................... I got two of the 5692 size and they are well made and get HIGH reviews....................and for the $$$$$$$$$!!!!

Thank you guys! I am receiving a lot of GOOD INFO here!!

I am not looking for huge speed, mainly because i will use it in the Atlantic Ocean, no water ponds in my island hahaha, so it will be a wake jumper hehehe so huge speed plus wake = Disaster hahaha

If you say that the 4082 leopard will move it and with the right prop i iwont have any temperature problems, i think that i will go for this option... The building of Forescott is amazing but way too PRO for me now hahaha

Thanks again!

A popular choice for the 4082 is 1600kv on 6s but thats in smaller hulls, pushing a larger hull thats heavier with more resistance will increase the load so you need to keep an eye on temps & not to bigger props. A better choice may be the 4082 - 1450kv in a large hull. Martin.

how about the t600 on 6s2p is that too much weight for the osprey? i consider t600 to be more beefy and should be able to push the boat

Awesome running hull. This is a TFL hobby hull and the bigger brother to the Pursuit mono, which we all know are amazing running hulls. I'm running mine with a CC1717, Hydra Ice 240 with a x447/3 on 6s2p and runs on rails. I had the Vanquish which is prob the worst hull I've ever owned. This hull is awesome though. Don't forget about the Leopard 4092 that steve sells now. The 1360kv (I think that's right) would run nice on 6s2p, id go for a swordy 240 though because I don't run escs to max voltage, just a me thing.... great boat though :)

Hey guys!!

I have 3 recommendations now:
- OSE Shop recommends 1250kv
- Diesel 6401 recommends 1360kv
- Martin recommends 1450kv
- Make a wake recommends 1450kv

For now 1450kv is taking the lead!! hehehe going for lower KVs what advantages will have?¿¿??¿ More torque, colder temp and slower??

Thanks guys

[Make-a-Wake]

You can run a bit larger prop with the lower kv motors............... but a smaller prop has less torque roll.

I'd probably split it and go with the 1360kv

The other models were 4082 size, I suggested the 4092 size also I was wrong the kv is actually 1390kv, the reason I picked that model is it is a wye "y" wind motor. http://www.offshoreelectrics.com/pro...o-4092&cat=148 the larger rotor should allow more torque and still fit in the stock mount. The aft support ring my not work though due to the length of the cooling jacket that isn't it a big deal though, just subsitute the ring for a zip-tie... Worked for me.

Lower kv = more torque, does not mean slower, you make up the difference with of lower rpm's with prop selection.

[martin]

I agree the 4092 is a much better choice than the 4082 if your sticking with 40 size motors & as stated i would deff go with the 1390kv on 6s, As Diesel6401 said its a y wind motor as well. Martin.
