Would this not do?

I know it's an "L". But this motor is only 12mm shorter than a 540 XL. And most likely has more torque. Im not talking from experience, simply speculation, but I think it'd work great.

I would stick with a 9XL as it will pull less amps than the 580L
the 580s pull alot of amps..

I'm not interested in the 45mm motors for this boat, I will be using a 36mm KD36-60-11L which has 2200KV and a max amp rating of 55amps.
I figure this motor will be low torque / high rpm ( 32560 rpm on 4S) so that I can use a small diameter prop to help reduce prop torque on this skinny hull.
Maybe I should use Reddy's favourite X537/3 prop, but that doesn't have a 4 in it !
Douggie - I haven't done any calculations, it's all just guesswork, but I will be using my Eagle Tree on the first runs as always.
I suspect if it pulls much more than 50 - 60 amps it's a lotttery as to which expires first, the motor or the ESC.

Good motor choice Graham, I would be using the same school of thought, high rpm's small prop. X440/3 would be the prop id start with :P

To be honest I would use an 9 to 12Xl motor with 4 to 5S power but I know this was a budget enterprise...Keep us posted Graham.

I'm with Douggie on this one!
I had a KD540 11L in my revo and it did not last long, pulled much more than the advertised 55amps got hot and burnt..
The KD 9XL is not much more in cost

[Brushless55]

and for only a few bucks more a real 11L would be a better choice over the KD

a bit more then a few dollars double the price i think most of the people on this thread miss the point of what Graham is trying to do EL cheepo build

[Brushless55]

Not missing the cheap build... The shipping from Hobbycity is high
after shipping the extra cost would be maybe 25bucks!
and actually could be less, may be only 15bucks

the shipping from hobbycity is very good actually, it cost me less to get one KB458XL from them then when i brought my etti 150 from OSE double the weight
i think we getting way off the real subject here

:

I bought a $30 motor and paid almost 20 bucks to get it shipped within 5days From Hobbycity, I could have paid less but usualy wait about two+ weeks to get my things.. I've bought a few items from OSE and only paid 8 bucks for shipping that came in the mail in two days!
Just to say OSE shipping kicks!
but the KDs to rock if you get a good one
I did a budget brushless on my revo, and picked a KD6XL and it flipin kicks

and back to the budget..

do you get a cut every time he sells something ??? you live in the states we don't

Where you live?
yep in the states his shipping is great and fast.. It's almost weird of how fast I get my parts from him..
and again the reason why I bought the KD6XL is I was building a budget Brushless Revo before they released the MMM Revo

So in the states the original L motor would be a good buy, but out of the states its still money saved for the KD..

[G Doggett]

The motor turned up today so thats 10 days from my order to my P O Box at an Air Freight cost of $12.12. ( Hong Kong to NZ )
I think thats pretty damn good.
I've given it a quick inspection and it seems OK, bearings ( yes it has ball bearings) seem smooth, and the shaft spins freely, and it has the alloy end plates.
I've treated it to an OSE cooling jacket and might find time this evening to bolt it onto the mount.
I'm not looking forward to programming the ESC wiggling the throttle and counting the beeps !

[Brushless55]

Great job and much cheaper shippijng than to the states..
keep us posted!
did you go with the 11L motor?
wish I would not have smoked my 11L, I would like to try it in my SV27.. it only had two runs, wish there was a cheap fix..

LOL My heli/ plane ESC's I can remember the voltage cutoff programing tone and soft/hard cut tone lol

what i would do is put it in programming mode, and just let it run through the whole programming mode, to get a rough idea of the tones and then unplug, compare with instructions and then do it.
