Default RE: 2 Post flight questions..


ORIGINAL: Pete737

It's a bit difficult to acurately diagnose what I believed to be possible issues with my F-16....Not ever having flown another jet but here' goes anyway.

-The ailerons felt weird, Both Jeff and I thought so, Jeff more importantly having flown 16's for 10 years or so. They seemed to ''wander'' a bit if that's the right term. Sometimes they would roll faster than others given identical input, If you saw the video, after takeoff halfway through the downwind there were 2 sharp rolls to the right, Those rolls were a result of the same aileron imput I gave later in the flight, Which had much milder re****s. I have 20% expo running 5645's. I don't know if that little bit of slop in the 5645 has anything to do with it, I plan to change them to 5955's anyway.

-The stabs are not flush with the speedbrakes, The airplane needed about 10 clicks of up elevator for straight and level flight. The TE of the stabs are roughly 3/8'' above the speedbrake. Jeff thinks its slightly nose heavy, CG is at 155mm right now. On that note, If I was willing to live with the CG situation which I probably am because the elevator feels great, How do you think the addition of a pilot would affect things?

Thanks! Pete

Hi Pete:

Like you, I am about to maiden my new SM F-16 1/8 after a fatal crash on Aug. 10, 2008.

Regarding your question about CG, read this thread:

About your ailerons, has you set aileron differential as stated in the manual?

Pleas post your maiden flight video
