Thanks for the promt reply. I think I follow what you mean, but can you just check this to make sure I've got it.

If I switch on the transmitter with the battery in the plane on sport mode, centre the trims and then move both control elevators down about a sixteenth of an inch or so, and then secure the lines ( this is about the maximum distance the trim moves, and I get level flight on half throttle when I do this ) And the trim switch is then centered, and I can use the trim for full throttle ? Will this slight down elevator effect the climb out ? if so do I use up elevator to counter act this ? I've also been told that if I add the wing shim to the trailing edge of the wing this will help ? My last question is...what is the standard thing to do, level the plane with elevator stick while flying? or adjust the attitude of the tail ?

Cheers again
