Good 6s-8s outrunner?

[FighterCat57]

Specs I'm looking for:
540 size mount holes (fits in my water cooled mount)
<50mm wide
<75mm long
2,500 + watt rating
5mm or 8mm shaft (prefer 5mm)
6s-8s Kv rating for 24-30k rpm. (1000 - 1500kv range)

Shooting for a low RPM, high torque, big prop setup. (32" single cat)

Any suggestions?

a hyperion -4025 / 890 kv , can handle 8s , which will give you 25000 rpm , i am runing one in a 540 water cooled mount , they are rated @ 2700 constant WATTS & 3700 max peak WATTS

That sounds perfect. The next question is where to get one. Google didn't help much.

Empire Hobby, is the US dealer .... they do make a 1100 kv motor in 4025 range , but it can only handle 5-6s & is rated @ 2200-2970 WATTS , i would go for the 890kv motor myself ....they have a 4035/4200 WATT motor range , but they will not fit in the 540 water cooled mount ....

Nice! Thanks!

What kind of performance are you getting from the boat it's in?

[scoota]

its in a DF mono , gpsing over 60 mph & the sound the outruners make is wicked !!!! Im doing a lot of testing with Hyperion products with the help of my dealer at present , there lipos are some of the best batteries i have run so far ... i know they are working on a new range of inrunners as we speak , cant wait to try them out as well ... all the outrunners are 90-95 % efficient ...

You also may want to check out Scorpion Motors @http://www.innov8tivedesigns.com/
They have a line of high power heli motors.
BTW Scorpion also manufactures motors for Hyperion.
I use both for my planes....yes I fly RC planes too, and like both brands. In fact these two brands are the only ones I use now, replacing old Axis with new Hyperions or Scorpions.
good luck!

It appears that the Scorpion and Hyperion outrunner motors are the same - at least some are. For example the 4025/1100 motors have the same specs and look identical except for the colours. I run a Scorpion 4025/1100 on 6S and like it a lot. Rated at 100 amps on 6S it handles more if fed enough air. It runs high 40s on 6S1P in a SprintCat 40 for a nice sport setup. On 8S the 890 Kv version might be a better choice.

You are right in saying that they are the same Fluid , call me one eyed , but i get better back up with Hyperion & better prices , i cant stand the guy that sells Scorpion stuff over here & he charges more for the same product . Yes the only down fall with the outrunner motors is they designed to have cold air flow into the front fan of the motor , which is a problem in a hull with its hatch taped down , i try not to run mine more then 2- 3 minutes at a time ,to keep the motor temps down...
