just a follow up:

I had to completely re-tape my tail this past week. the white "tedlar" tape had almost completely let go around the perimeter of the tail. I used some of the roll I got from GC industries and it just feels a lot better after i shrunk it.

Still have a bit of tail shake, I now suspect my cross tube between the tail feathers as it is a little bit bent from running into my shin a while ago....replacing with stronger tube.

Side note - i installed one of those "capacitance" type fuel probe and gauge and it seems to be working really nice so far even with 2-stroke mixed fuel. the needle doesn't bounce around and is showing a good representation of actual fuel in the tank. (i have a black fuel tank so can't see the fuel).

nice 45 minute flight last night tooling around local fields - boy the crops are long this time of year - look for the fields with bails in them for a forced landing rather than the nice smooth looking field of 4' canola :)

PS: drooling over dave's new wheels/brakes - did you measure any weight penalty/gain?

Tail shaking "could" be caused by improper tail brace cable tension. Replace those cables and the shaking may go away or lessen to the normal level (no guarantees however).

my wires are tight - i wonder if wires being too tight is a problem though... haven't been out to the field yet to replace the spreader tube, so once i do that i'll let you know - and if it doesn't work i'll turn to turnbuckles on the wires and start experimenting with different tensions.

tail shake had all but disappeared - then i filled up with gas before my flight today and it reappeared. i am thinking that shake occurs as the CofG approaches the rear limit now - as my 2-seater is tail heavy and i can carry 8 gallons of gas. i also added my cargo bag on again, but i'll be taking it off as its too far back now (with new gas tank setup).
