When reading through this pdf, one sentence caught my special attention: 'It’s now appearing in World-Championship Control-line as well.'
I know, I was there when the first 4 pilots flew under electric power, WCh 2006:

I'm the one on the right... :mrgreen:

After doing the conversion of your estimate into kilos, I can tell you, you're not far off.
The model in the picture (as well as Bob Hunt's -World Champion 1978- Genesis Extreme) is powered by a AXI 2826-10 on 4S4200mAh, 12.5 x 6 Graupner CAM E prop.
It's the converted Blue Pearl by Henk de Jong (published in AM) and we decided I should fly it that WCh.
Timer was a one off, that enabled me to crank up the power another 5% or so after the horizontal eights.
Still, flying with just governor proved not enough in anything but perfect weather.
In that case it was a formidable stunt weapon, in anything else a handful.

My current model has a Torcman NT350, capable of 800 Watt peak.
Coupled with an APC 13 x 6.5 E/F2B it's really something.
Model weight is 1735 grams
Aiming at 5.25 - 5.35 sec lap times it pulls like a freight train (relatively speaking, for such a relative small model).
I flew it in contest in Germany last weekend and in spite of the sometimes lively breeze it remained very controllable.

Hello All
I'm new here and I was wondering if there were any UK participants in the "Worldwide Ringmaster Fly a Thon" ?? We had a nice turn out here in Memphis, TN USA.. just wondered what went on in the UK.. I built an 850 in^2 Ringmaster with a ST Bluehead .61 with the next iteration of this wireless throttle that worked very well..
Take care,
Al

Hi Al,

I don't want to be speaking for anyone else, but the Ringmaster was never well known in my country (of course now it is, due to the internet), so it doesn't have the status here like it has in the US.
Most trainer models we were familiar with, were local developments (admitted, using a lot of US techniques, only years behind... ;) )
My first model of US design I made in 1973 was a modified "Gieseke" Nobler, that helped me qualify for our national team...

A Ringmaster with a ST 61 Blue head... :o That should be more than a handful..... :lol:

Bruno

Very, very nice indeed!

All seem from the time I remember well, when 'fun flying' could be anything, but mostly FF & CL, as RC was something only 'experts' dared trying.

Then there is this model... :?: :roll:
I do recognise it, but for the dear life of me, I couldn't remember the name and origin.
The one I remember was powered by a Wen Mac .049
