Mike,
No, I have not noticed any problems with yaw stability to date. She seems to
fly even better with the floats. I removed the trim tab on my rudder last
night as the floats offset any correction I had been using the trim for. I am
considering taking off the lower dorsal fin this winter and increasing the
size of my aluminum V-stab to make up the difference when I go to wheels or
skis. However, your comment about then having more trouble landing in
crosswinds on wheels is worth thinking about. Hmmmmmmm.......Gotta love this
EXPERIMENTAL stuff.
All I know is last night the dorsal fin was working because it took me 3 tries
to get my SR up to the dock at my cabin. Every time I'd get close to the dock
and shut down the wind would decide it was going to put me anywhere but my
cabin. On the third docking try I pushed my Dad out of the plane with a
paddle and told him to "go to manual propulsion systems". We needed the
exercise anyways. (Mental note to self, practice seaplane sailing this
weekend. I vaguely remember my instructor mentioning this concept last year
but at the time, out in the middle of a big old lake, it didn't seem so
critical).
One last motivational comment. Last night while climbing out of Lake Hood the
tower told me to watch out for a C-130 out of Elmendorf and then asked if he
could ask a personal question. I figured he wanted to know why I was
violating whatever airspace I was violating at the time, but instead he asked
how much horsepower I had. I told him 250 and he came back with "ahh...that
explains it" I guess we are jumping out of the water pretty well. It sure
feels nice, especially that surge of acceleration once you break free of the
water.
Keep building. It's worth it.
