Matt - I never found instructions on that point either. It struck me that on the first flight you want to be able to trim for slow flight, approach, so that requires more than normal up elevator, trim tab down. So I adjusted mine with a little extra down rather than up. I havnt flown the -4 yet though, so I have no confirmation that I did the correct thing. As to throw, when I built my -9a the movement in the cruise around the centre was minimal, it caused me to include a gizmo to slow the trim down on the -4. The only time I saw significant movement from the middle was CofG forward trimming for approach. (Trim down.)

Hello Listers, What is the common opinion on the reuse of those aero-nuts with the little nylon insert? Seems like once you use one and take it off the strength of the nylon isn't as good any longer. Is there a "recommended" number of uses for them? Thanks, Matt ________________________________ Message 3 _____________________________________ Time: 11:06:11 AM PST US From: Rob Ray Subject: Re: RV4-List: Aero-net Reuse...
