How do you figure that pitching up is a sign of the CG being forward?
I'm not trying to pick a fight, I'm actually curious because I just mounted a GoPro Hero2 to my super cub and shes trying to go high alpha on me when I give it throttle it seems.
I thought I had it balanced pretty well but maybe not?
Knowing this may very well save my plane.

Generally you'll trim a plane for level flight at some speed below full throttle. If the CG is too far forward the plane will naturally want to dive, which causes you to add more up-trim than normal. Now when you exceed that speed, the elevator is pushing harder and starts to pitch the plane up.

With a plane like the SuperCub, the wing will naturally produce more lift as you speed it up, which also results in a climb even if the CG and trim are good. By contrast, a more 'neutral' plane, such as a pattern ship with a symmetrical wing, won't do that if it's trimmed correctly and has appropriate thrust angles.

Damn, you got some nice flying territory there Great flying, too. For some reason those GoPro cameras always make me feel a little disoreinted, like I'm looking at the world through in a fisheye mirror. Still awesome, though

I'm hoping to maybe get some flying done in the next couple days. This is a very strange winter; we've had a total of just a couple inches of snow and the temps are bouncing around like crazy. A few days ago I was out for a bike ride in a light sweater over a t-shirt, and this morning it was four degrees on the way to school. I saw the bank sign and thought it said 34 because it just didn't feel that cold

Anywho, I'm hesitant to charge up any packs due to the possibility of the weather tanking, which would compel me to just discharge them back to storage rather than waiting it out. I'd rather avoid all that but I don't have enough daylight on weekdays to get home, toss one on the charger, and go fly if the weather's good.

I DO have my mCX, though

After a torrential rainstorm yesterday today was perfect flying weather. Some friends came over and we had a fun day flying. I gotta get me a slow stick. I also am gonna get me a paved runway down so I can get me a P-51 with some retracts and a jet like these guys had. Trying to get a group of flyers together, no AMA card needed, but O.K. /Ms. gulf coast, NOLA and USM flyers come on down! The more the/ U know.. Zee

Well at least it looks like the winds will calm down a bit for Saturday evening and Sunday morning. I'll have to take out my jug.

From the land down under. It was a balmy 27 degrees Celsius last night at about 9.30pm.

My mate and I went night flying. Drew in some curious spectators as usual, including a security guard and a few drunk people.
There was nil wind. Awesome flying!

Got a new prop for the T-28. Hoping the winds die down tomorrow so we can get some air time in.


P.S. Watching the classic flick "Tora!Tora!Tora!" on the Military channel.

I didn't get to fly any planes myself, but there were 2 successful maidens this morning in our club. One was a Sig Four Star 20EP - the beginning of the maiden was a bit rough, but once the pilot got the trims figured out, it flew beautifully. The other was a Tuff Trainer, which also flew great - but the -15* motor pitch did unnerve everyone until we figured out that it was designed to be that way.

If we get lucky to assemble again this afternoon, I'll be bringing my Mini Telemaster out, which I haven't flown in around 4 months. Did a thorough motor/ESC check, reworked some wires, and added flaperons.

The last time I attempted flaperons on the Telemaster, the pushrods were loose so one of the aileron didn't respond in the middle of the flight. The plane originally shipped in with an aileron wing and another without, so I had converted it some time ago. But now that the aileron wing is horribly warped, I simply "cannibalized" the aileron wing - took the strong original pushrods and used them on my flaperon wing. So far, things are looking good. I just need to get my old Optic 6 charged up, program a few things, and go fly.
