Electric 'go fast' motor for a Swist

OK so as I await the imminent arrival of my Swist and its 10x23 prop my attention turns to power trains to drag it around the sky.
The manufacturers choice would be the kontronic Kira 480-34 on 5S and tests on this set up have come back at 340-360kmh (225mph) at around 60A continuous and 100A at start.
I do not want to push the airframe like Sebbe with his turbine powered one. Nor do i want to variate much from the standard install and linkages.
The model is for sport flying not F5D so I am unrestricted by power consumption.

What do you think? How about the higher KV Kira's?

Andy

Hi Andy,
I'm very much interested in similar setups and have started to collect info in my blog. Consequently I would be interested in where you got the data you referenced!

I'm concerned about how useful some of the powertrain information being provided by the prop manufacturers for us sportfliers who expect our motors to last more than a few flights, don't live in arctic conditions or don't want to spray our motors with freon before we fly. I even know someone who has recently burnt two Kira's testing double overpitch props for pylon racing.

So what am I saying?

Please post any good data you come across, as I know there is a few of us very interested!
I think you would want a lower kV Kira, not higher kV
Maybe a larger geared motor might be a better long term bet than a 480 sized motor. What that motor is, I'm still searching!

I suspect until more of us buy and test some of these prop and motor combinations, we won't really know.

Cheers
Peter

I'm not really in to outrunners(yet) but I've seen impressive results with the Kontronik pyro motors and I have my self tried a "small" Scorpion 4035 at 6kW with no problem at all. Thinking one of the Scorpion motor of the right weight would be a good option. Cutting the nose mounting it F3S style. I do not know if the powercroco range are available or which sizes, they seem bullet proof too.
