Prop - yeah, I broke that beautiful motor in for about an hour the other day. Seeing the Twist with a Saito 82 in it is like looking at an old muscle car that has a hole cut in the hood so the heads and carbs can stick out. Haha.

Hey guys, I still haven't gotten her in the air yet. I just haven't yet had the opportunity to go out to the field yet. And now that I'm ready, it sounds like our airfield is going to be flooded by about 12:00 noon on Thursday as the minnesota river is raising up pretty fast. Our field is in a sort of flood plains area that has a chance of flooding about 1 a year or twice on a really bad year.

But I've got a couple quick questions for you experienced Twist'ers. I go back and forth about what type of control surface throws that I should use on the maiden flight. I'm a pretty new flyer but pretty confident as well. I'm worried that If I make them too low of throws, that I won't be able to get out of a bind if I need to? I taxied my plane around the street using aproximately 1" of throw in the rudder and I could hardly turn the plane in a 20 foot radius. Would it be better to use larger throws and use like 80% Exponential as opposed to .75" or 1" max throws? What should I expect on this plane during the first flight? My CG is somewhere between 4-1/2" and 4-3/4" currently. I've got the battery in the standard tray area and the receiver behind the throttle servo. I'd move the receiver but its so light, is it going to change the CG at all?
Why not set it up as the manual indicates? It's not surprising that you are not getting much turn authority taxiing with 1" throw on the rudder? The recommended low rate is 1 3/4" each direction. High rate is 2".

I use 50% expo on elevator and ailerons and it seems comfortable. Best of luck on your maiden.
