    Hi all,

    I have been meaning to post, but havent had a chance. My Avid is a little heavy and near the forward CG limit when I fly. (this is according to the C.G. data that came with the plane, but I haven't personally weighed the A/C to find out if the numbers are right) I have looked behind with the door off while flying and can see that the elevator it deflected up a few degrees when flying level. Also I have to hold a tiny bit of back pressure on the stick, and if I let go it starts a very gentle dive. (no pitch trim installed, trim tab only) All of this seems consistent with a nose heavy plane. I added five pounds to the tail but after calculations, it showed that it only makes roughly 1 inch of CG difference. Right now its about 12.5 inches aft datum when flying. I was suprised that the weight seemed to have almost no effect on the flying characteristics or trim. I don't seem to "run out" of elevator when landing, or have any real controllability problems, Otherwise it seems to fly really well. (I have noticed at lower speeds when I pull flaps in I need significantly more back pressure on the stick, which is a bit awkward. I end up landing zero flaps) Im just concerned about getting the trim well balanced. Also its nice not to have to hold back pressure for long periods of time. The more weight I add the lower my useful load, so I was thinking about adding the VGs to my horizontal to see if that helps. Seems like this might provide more total downforce at high elevator deflections, but nearly nothing for cruise trim? I guess nothing will actually correct it but adding more weight to the tail, but that will start to cut into my ability to carry a passenger. Just curious about your thoughts and observations from the work you have all done so far. What normal cg range is are all of your planes when loaded for flight? If I add pitch trim, how do you all have the control set up in the cockpit for simplicity and where did you find room for it?

    Thanks in advance

    I think my airspeed is very accurate because when I bought it the static source was the cockpit. I found that the air disturbances around the cockpit gave innacurate airspeed indications due to venturi effect around the cockpit giving an atrificially high pitot to static comparison. .01 PSI is equal to 60 MPH of airspeed indication (thats right .01!) So I added a pitot static mast in the original pitot location so the pitot static comparison is taken at the exact sxame location. There should be no total dynamic pressure variations at different locations since they are one and the same now. It is a bit difficult to fully stall (which adds fuel to the nose heavy scenario) but when I stall its around 35 MPH indicated.

    Im really happy with my Avid so far and have been having lots of fun. Looking forward to your inputs.

    That's awesome! Congratulations. From what I can see it looks really nice too. Be safe and have fun.

    Hello all,

    I am a new member to the forums, but am very excited to see and share information. I live in the Denver, Colorado area. I have an Avid C that I bought about 9 months ago, but due to tinkering with it in the winter, and work circumstances during the spring and early summer,I am just now getting out to fly it. I flew for a few hours this Monday, and am looking forward to getting back out there again this weekend. I don't have a transponder, so I have to keep my plane and fly a bit far away, about an hours drive. So far it has been a very fun airplane and i keep the wings folded which has cut my hangar bill in half. My Avid has a Subaru EA-81 with an NSI reduction unit and a warp drive 3 blade prop. It seems to climb really well even in Denver. When I flew Monday the density altitude was nearly 7000 feet!

    Looking forward to sharing information and picking the brains of you who probably know alot more about Avids than myself.
