Electricityfied...!

Motley's started the electrification of the 40% K8 Line. So far the budget has doubled and it's two years late... No, wait, that's the South West Line. :D :D :D This is Mott's 'spare' Phoenix K8, the big one: the motor has been shoehorned in with the help of some Smallpiece type engineering. There's a tow release buried in there too...

Oh i trust him Frank,but have you seen the rates he charges? :D Anyway it's only experimental : I.e. "a little experience and perhaps a tad mental" :lol:

Geoff,
Good idea sticking it in the nose :D I have one of the G160 motors on 8s with a 20x8 wooden prop that gives 2000 watts at 69 amps and will fly your K8 , are you using 10s ?
cheers Euan.

;) Hope he allows for motor cooling air! Ter

Euan, Just done a bench test using 10s with 18.5x10 folding prop (way too much power) & nearly dragged me off my feet, so still experimenting. :)
Terry, yes I've made provision for cooling, that's what those 2 holes are for each side of the motor shaft exit. There should also be some additional air flow via the tow release situated further down. However, WIP as they say. :)

You can also use a spinner with a cooling hole as this direct feed to the motor: http://www.4-max.co.uk/folding-props-spinners.htm

It'll have plenty of time for cooling while he thermals around for a couple of hours between motor runs :D

I have dreams like that too. Never happens though...
