When he was trying to sell it on Barnstormers there was no mention of any of this. I also wonder if he realizes that on his web site in his own words he says of this exact airplane, "Viking Waiex - 160 mph cruise and a BLAST to fly." That quote and the photo of the plane is here (1/2 way down the page):

So he was either lying then or now ...

I have flown my Jabiru powered Waiex (10 more HP than the Viking) at 160MPH (TAS) cruise and will confirm its a BLAST to fly. No lie there. No need to adjust the wing incidence, nor the tail. In fact, its amazingly hands off at that speed.
Perhaps, Jan should consult with Kerry or Jeremy before re-rigging his wings and adjusting the tail. Or read the NTSB report on the deadly Waiex incident. That's a very significant mod to the design and should probably get a professional engineer to review it. Seems to me to be a thrust vector problem. Either the Viking plane was built twisted, or his engine mount isn't appropriate for the airframe.
I sure hope he's done the tail SB. Wouldn't want that tail shaking off at those incredible speeds the Viking delivers. Seconds to cruise speed is very impressive. Must really throw you back in the seat.
