After trying out the Corvair, Richard spent 6 months and some money to redo his airplane with a Viking 130 engine.  He made aviation history yesterday by being the first to fly a low winged Zenith aircraft with the Viking 130 engine model.  I spoke with him today and he could not stop talking about what a huge difference the engine has made to his airplane.  We hope to have a takeoff video from him shortly in order to get a before / after comparison to the airplane being powered with the earlier engine.  Richard already has a video showing that.  

Congratulations are in order for a job well done.  He used the Homebuilthelp Viking installation DVD and said it made all the difference.  

Dick has set his Wordwind prop pitch to 22 degrees and will fly more this weekend.  Cant wait to get his before / after data.  He has weighed his airplane to get the new CG and it was within half lbs of the Corvair engine, ready to fly - fluids, radiator and all

Which model Corvair did Dick have? If he traded a 100 HP Corvair for a 130 HP Viking the performance increase would be significant. If he had a 130 HP Corvair I would expect less difference. He could have traded a 100 HP Corvair for a 130 HP "stroker" and got a similar boost, I expect.

I await comparison numbers with interest.
