Ekas,
Only address i know for Ola is:
http://home.online.no/~ofremmi/
Yea he's a real nice guy. Discussed at length with him wing design couple of years back at EC in Zamora. Result was i modified my Alliance wing and im currently flying a modified Synergy. Both go extremely well.
He flys with the OS 140 in both F3A and 3D so he knows the engine inside out.
