phase 6 test flight

<< < (5/15) > >>

luke:
well keith,
              sorry bout your misshap, funny you should say that becouse my phase 6 has to be pulled out of a dive, she wont come out herself, and this tends to be a little scary when your winding up for a loop(s) i think i have c.g. issues , what im doing at the moment in an attempt to lighten her a little is drill 11/2 inch holes down the side of the fuse and do the same with the elevator and rudder, i dont know, it mabey a fools errand but worth a try coz theres waaaay too much lead in the nose to balance her.i reckon i might have saved 20g-50g already
hope everything fixes right for you fred
hope you will be in the air soon

Drilling holes to balance her :shock:  With respect Luke are you sure you're testing her balance in the right point? Should be 4 1/2 inches back from the LE. At that point she should either remain horizontal or just tip slightly forward. I haven't heard of anyone having to drill holes to balance a Phase 6.

F.Y.I. I suggest you do a quick check of the elevator linkage. :wink:  The problem with mine was that the 'elevator rod pivot lever' in the tail became un-welded. Check to see if yours is okay by holding the elevator and operating the elevator stick forward and back. Keep an eye on the elevator servo and if you see the servo moving but can't feel the elevator move by an equivalent amount I'd say you've got the same problem. (Eventually the weld on mine gave out completely, that's why she went nose in.)

On a slightly different note, I belive the Cork club have a Fly-In around this time of year. I'd hope to make it and if you did as well we could meet up and compare notes. It'd be nice to put a face to the name, so to speak!

luke:
your right ther fred , that could be another thing to check. i think your missing me there a bit, what im trying to do is lighten her, and try to make her a little bit more user friendly. im going to try and reduce the angle of incidence in the wing, if i put a 2mm strip uder the t.e. of the wing it reduces the angle of incidence by 1 degree,

yeah that would be nice alright , meet other sick people like myself  :lol:
but im very rarely down cork way . im usually around killaloe,

Fred:
Hey Luke,

Keith, not Fred ! I am much more beautifull, and young ! (and a bit fat as well...  :lol: )

The incidence depend of you CofG too, both are related. Changing the incidence will not necessarely fix your problem as you have to work on both front at the same time.

In flight, if you do the dive test, what happen ? That will be your best guess to see if something is wrong or not.

Happy Days:
My dear Fred,

Younger than me, you may be........ :oops:

More knowledgeable than me in matters of aerodynamics, you may be,...... :oops:

But better looking? :shock: ........ Definitely NOT :roll:
