Im anxious to try the turnigy since it adds weight
Edit: So today I flew the bird twice paying close attention to CG. My CG was exactly as described previously. However......
1. Using the newer Admiral 5000, she tends to leap off the runway. A strong gust or too much back pressure and you may be going vertical.
I've always just used a very slight back pressure or none at all. Today I had to pull because of the approaching high grass. She went vertical.
2. Using the Turnigy HD 5000 brick, she tends to liftoff in a more scale manner and penetrate the wind easier. Landing speeds can be a bit higher.
Also sink rate can be an issue with tanks on. The heavier battery makes this a little more obvious. I flew 3:55 and landed at 3.78v/cell on the brick.
3. I had a runway abort on takeoff #2. Apparently I had let the empty bird rest on the back of the drop tanks in between battery changes. Unknown to me, this had dislodged the forward magnets' hold on both tanks. During the takeoff roll, the port tank separated. I jettisoned the starboard tank and pulled power. Taxied back and re-loaded the tanks. The idea was to fly with tanks after all. Subsequent flights were a non-issue.
4. My judgment is still good I guess. After two flights on this horrendously windy and turbulent day, I decided to scrub and go home.
My buddy lost his Flightline Spitty today in that wind. I felt like the A-4 was getting a beating in the air. I stopped at two flights after the wind picked up more.
I may or may not have video of today's adventures. We shall see.
