OK, couple of dumb questions:
Has anyone thought about the CG on this heli? It seems having the CG too far back will cause the heli to want to pop nose up as soon as you get a little forward speed, and if left alone, it will quickly drop back into a "descending hover".

I can't speak to the flattened flybar.... yet. I have some other issues to fix before I can do that to my heli, but it is coming, and soon.

As for flying in high winds... I was on the phone with Matt, I know he actually did it. Also, my corona is relatively stock (belt main and tail, BL, Crazy Crutch and CF feather plate) and I like to use it for slope soaring...

Man, I hadn't even remembered that! Geeze, I had the phone at my ear (talking to Dave) while flying in the gail force winds in front of my house the other day. I had to tell him to hold on a minute while I fought the heli down! That was a COOL flight!

Matt..........

How critical is the CG on the Corona? I try to position the battery so that sighting the main shaft while holding the grips shows it to be vertical. If I happen to get it off I seem to notice a big difference in behavior. Would it be better dead on or a little forward?

Not really. I just center it.

Ok. That is what I have been doing. I was about to try flattening my flybar but you guys have almost scared me off talking about how twitchy it makes the heli. I have enough trouble with it in stock configuration at my (lack of) skill level.

The stock flybar flattened is not twitchy (or not that I have noticed). The carbon flybar is a bit. I would give it a go if you like forward flight.

Going backwards a little, re: CG on the Corona..

I am a freak (did I say that out loud?). I go dead on center for hover practice, etc.. And then I go a little forward for forward flight. I judge my CG by holding the grips and then looking at the tail boom. For a forward CG, I let the tail raise about 1/4" .

I found it helped a little in keeping the "popping" down.

Good tip on sighting the boom. Thanks. I am still learning. Mostly hovering and piros so I will try to keep the boom level when setting my battery position.

I tend to get it relatively close, but not absolute. the trim will change a bit with 8cell, but not too much. it does matter a lot if you want hands off hover though.
