I know a man who can but I will say this.
Squeeze ALL the ball joints into submission! I didn't and the maiden flight
was interesting. The whole rotor head was so stiff that it would NOT return
properly to neutral positions! I spent about two hours on Saturday night
going through the system and now the head is so smooth!
When Beav set up the Logo this is what he did.
First he set ALL the links to the 3D lengths to maximise the pitch ranges.
Starting with Idle up 2 hover pitch was as near to 0 as makes no difference.
Top and bottom give about + - 12 degrees which is good. All done
mechanically.
The remaining pitch curves were set electronically in the tranny as follows:
Idle Up 1. This gives about - 5 at the bottom and the about + 11 ish at the
top.
Normal mode is about -3 +8 and +11 ish at the top.
One thing to note. Following Sunday's flying I found the Logo 10 VERY
responsive to cyclic inputs. We dialled in 50% expo to smooth things down.
I've NEVER flown expo before! This evening I've just noticed I had the
mixing links the wrong way round at the top of the main mast! You need the
shorter arm nearest the mast and attached to the swash, the longer arm goes
to the flybar.
The tail is a bit twitchy at the moment, not sure why. Have just gone
through the entire tail linkage easing things but things were quite good
before. Hmm...
I've set up the ESC in normal mode so I followed the advised throttle
curves. They're good to go. Will probably change over to governor mode this
weekend, if not before.
Let me know how you get on.
