Electric Pearl ?

I have read that the orignal Blue Pearl stunter has been taken out of storage and converted to electric power! Apparently it goes very well.

Electric Pearl
Indeed, Blue Pearl has been converted to E power in 2006, to be retired in 2008.
It was the second attempt by Henk de Jong (design, builder), Erik Janssen (allround problem solver) and Bruno van Hoek ( Electronics and test pilot), who had been together in the Dutch F2B 1994 WCh team.
Bruno came up with the first working F2B E-powertrain in the Netherlands and Henk provided the test models. Blue Pearl proved to be the best option on the second try. Erik took care of all the mechanical work, needed for the onversion.
Only 5 weeks before the WCh 2006 they managed to have the model flying and in trimmed condition. Bruno was appointed test pilot and took the model to Valladolid. He turned out to be one out of the first four pilots ever to fly F2B at a WCh.
In the relatively calm, hot weather, all went really well:
Later that year, going from a 12 x 6 Graupner CAM E prop to a 12.5 x 6 gave some improvement and in good flying conditions the model performed OK:
In windy weather the set up (with AXI 2826-10) proved to be not good enough, losing too much line tension when climbing against the wind ( vertical & overhead eights, hourglass & clover) WCh 2008 proved this as results were way below average.
Blue Pearl was retired after that.
Itís successor, Bluegrass Blitz , has a better powertrain and can cope with less than favourable circumstances.
I donít have a plan, the model was made from rough sketches and built mainly freehand.
