After doing some playing about in the garage to keep the 50mm props I would run her on 6 volts initially and if she isn't fast enough go for 12 volts.

Thanks.
Now for a little playing, (look out fish in my test centre, pond)

Goodness sake DON'T be CONNED like I was by him to buy his Buller motors they were POO POO would not rev much above 2000rpm ended up having to buy a proper motor which incidentally was cheaper and far superior.Try giving Red Bank Models a ring he is on this forum as winnergaz he sells Protech far better than Model Motors direct.This is a personal opinion don't believe me then pm either Welsh Druid or Robert Davies they both saw the patheticness of Alistairs motor even on 24v

.I know there are a lot better efforts around, but I will learn. ( Hopefully from the masters).
Would be grateful for any comments or idea`s.

it look ok to me you built or restored it be proud of your work good job

Thanks Stavros, MMD does sound to be a little slow running, I`ll take a look at redbank. My main concern is postage, as some are cheap but then hit you for six with postage.
And thanks to others for comments, it is always nice & encouraging to receive compliments from anyone, especially when some of you have so much experience.

How do you measure the RPM of a motor??

[justboatonic]

Talking of esc's, does anyone know if \ where the H Wing (otherwise may be known as Hobby Wing) brushless esc's can be obtained in the UK?

I have a hand held Tachometer which I use to check ALL my motors.

How do you do it on the move as the readings are different ?

I do most as free running in conjunction with a voltmeter/ammeter.
For a direct comparison between motors the free running speed is a good start point.
I usually test with a coupling end on the motor.
To apply load I just grab the coupling, being careful of course and read speed and current.
It will only give a reasonable guide but does me.
I just use my "vast experience of prop loadings" ( that means just guess ) and grab it till it  it loads up.
It does depend on prop size and pitch, but this does give a reasonable guide to the motors performance and tells immediately if say, a 545 is a plodder or screamer.
