HobbyKing Raven 990 @ the sink hole

HobbyKing Raven 990 @ the sink hole day 2 (14 min 26 sec)

Raven 990 @ the sink hole ...

When I walked out the door , it was overcast and there was no wind ...
By the time I got to the park ( walking ) there was blue sky and WIND ...

CG on the Raven is 75mm from the L/E and it's just too far back ..
In calm conditions it's ok , but with the wind .. It was just a PITA , and there was no tuning that would help ...

Suffice to say , besides the exercise I got .. It was pretty much a waste of time , ok I got some stick time .. ( And exercise )

When I went home , I shoved in enough LEAD into the nose to bring the CG to about 65mm from the L/E
I just need to edit some video and you can see what difference it made ...
As I went out this morning and broke the Raven 990 some more ..
