Savannah Karl

Well the Savannah S with a Viking 130 engine is flying and flying well. I’ve only got a few hours after getting the airworthiness certificate on Thursday the 20th but man that engine just sings. Today was a day for slow flight and a power off clean stall. I saw 29 mph and she never broke. Just began to settle at about 400 feet per minute straight ahead. I always had aileron authority perfectly controllable.

Okay guys I know it been quite a while for me but I just wanted to get you all updated on progress being made. We did a thrust test today and here are the results. 545lbs of thrust with a Viking 130 and a 68” whirlwind spinning at 5700 rpm.  I obviously have to adjust for a bigger bite but man that engine just sings.  That’s a lot of thrust for a 770lb Savannah S.  I know that sounds a little heavy for a Savannah but I’ve gone a little overboard on all the “extra” things I wanted.  Glove box, self designed center pedestal, extended range fuel tanks among other things.  I wasn’t as concerned with the final weight as some.  Im very happy with the number that came in.  I also figured the balance today and with no ballast were right at the forward limit of the cg assuming a 200 lb pilot (me on a good day?.)  I purpose built the airplane to avoid ballast.  Don’t let anyone tell you the Viking is too heavy.  Great day today.  [ATTACH]38791[/ATTACH] [ATTACH]38792[/ATTACH]
