    Well you have had exposure to creativity that is for sure and that is Half the battle and will get you 5% of the way there to building an aircraft successfully. Having an aircraft like an avid has taught me more about physics than I could ever glean from just classroom programming, and if it is there to be had for you you will get it the same way. Remember that Dean Wilson never formally finished high school says a lot about the man he is and what the education system basically isn't doing.

    Here is the exact location and just a chat room inquiry that might be as you figure not correct......

    Tiny Tach Autopsy
    So most of us here have been using or had a tiny tach and have eventually seen the day where it succumed to the 5 year life expectancy and quit working....rather than just buy a new one I decided to do an exploratory crack open of mine before permanently abandoning it. Breaking it open did mangle the case a bit . This one was only glued along the bottom edge of the rectangular box. If they are all glued in the same manner then damage getting them open can be minimized only prying on the bottom edge. Once it was open, the only visual I got of the internals was a 3 volt lithium cell partially visible under a thin skin of some sort of rubbery injected foam stuff. The cell itself is attached to the power leads via a couple of small spot welds. Managed to pry the cell from its foam lair with some screwdriver prying on the leads. The cell was a 2325 designated. Closest I could come up with was a 2025 at a cost of 45 cents. Smaller diameter but identical/required thickness. Dabbed a bit of dialectric grease on the leads and installed the battery. powered up and all functions seemed normal. Got some gel form krazy glue and put a drop only on the 4 corners of the housing. Squeezed everything back together with 4 rubber tipped spring clamps and let the glue dry. Reinstalled it the next day and all functions are operational as original. Be interesting to see how long the fix works with the slightly smaller battery but at $.45 out of pocket and time it is worth a try and it works.

    So how exactly are the crankcases vented on these engines? If you aren't vented properly or freely or have a pvc valve type  issue that is rpm dependent or related and build up crankcase pressure that could make for a crap idle situation maybe... this is a long shot but you have been chasing carb issues and everything seems to be checking out...

    Possibly a fuel pump pulse line collapse temperature related.  or maybe the pump pulse diaphragm has a crack in it creating an intermittent leak?

    I think when you reply to the thread there will be a paper clip thing that says drag or choose files. if you hit the choose files it will prompt your computer and you then can attach the video that way or if it is a video already on utube there is the insert other media at the bottom to stick that on here.

    Hey Paul this is something that may be of interest to you. Thought about how this might work on the tops of the flaperons to keep the boundary layer attached. People have also been toying around with the idea of putting vortex generators on the underside of the wing. Don't know if anyone has. I would think putting them right on the underside of the spar between the tip and lift strut could get the boundary layer sticking better out there in that somewhat over twisted portion of the wing area. 
    All that vortelator is, is thick vinyl that has been pinked with a somewhat courser than scissor pattern. I did buy some but never did anything with it so far.

    So is there actually still an avid flyer yahoo group? Google search for me shows nothing....

    Just a thought... you did purge the rotary valve chamber at the bleed screw located above the water pump? some people haven't because they didn't know about it and trashed their engine and plane in that order because of it.

    Well I will add my ....expertise... to everyone else's that has posted here. It effectively becomes about the horizontal distance between the attachment points of the airframe and the engine and the leverage that can then be generated at/near the weld points to create points of force that effectively exceed the strength of the steel and lead to points of cracking that become lines of cracking and everything then goes for shit and breaks eventually.

  13. saskavid added a post in a topic Avid STOL airfoil -some calculations   

    With Dean's design history(ellipse, bellanca eagle, explorer and others) I don't think he goofed  anything when he designed the stol airfoil. It was initially a very light plane design with not a lot of horse power to start and not carrying a lot of inertia over the fence so to speak so he did some things to compensate for the unexpected and unfamiliar. You see and hear of some pretty scary sustained  angle of climb demonstrations at reduced air speeds by pilots who know the plane and what it can do. I am not one of them. Like leni said the design was simple so as to get would be builders into the air successfully. In many cases improving upon the design involves taking what was once simple and creating complexity that can make success of completion a nonevent. 
    I learned sme time ago that anything mechanical designed to do something and work is only ever going to be conceived as an amalgamation of compromises. Many considerations made Dean Wilson make the design the way he did.

    This old june 1996 news letter has some general overview into the airfoils Dean Wilson did on the avid and why he did the undercamber the way he did on the stol version.
