    Hi Ed,
    Regarding the MEK with PVC: MEK is (or at least used to be) what the primer/cleaner for gluing PVC was made of. Softens it up for a bit.

    Rotax inverted installation eliminates the vent line from the cylinder head. Probably won't hurt anything except has extra weight and potential failure points.

    My Repair Manual for the model 90 (Gray head) calls for .9 bar (13#).

    Small world it is, I look forward to meeting you guys at Oshkosh, this year I plan to be there all week. I'm usually in the southeast corner of the back field, generally showing up mid day Sunday with a lawnmower.

    I've been trying to make it to Zorbaz on skis for a few years, always conflicts with weather, work, or whatever... perhaps next year, though I don't see skis going on the Avid until a taildragger conversion.

    I'll try harder to catch you at Oshkosh this year too, usually pretty rushed there but should have a bit more time this year. I camp with a travel trailer at De Relleumdats.

    Hi Brett,
    I sure know how the slowly part goes. Hopefully I'll make it to the Moberg flyin in Bemidji again this year - kinda in the neighborhood anyway.

    NE Minnesota new guy
    High time I introduce myself, Mark Johnston. I live about 50 miles from Jim Chuk and have visited with him occasionally at flyins for a few years. Been flying ~15 years, used to be a joint owner in a Piper Arrow, flew with CAP ~2004 to 2011, built a weight-shift control trike with some salvage and lots of influence from a Cosmos Phase II trike (582 gray head), and been building a scratch build 4 place Bearhawk for way too long - and it will be for a while yet. The trike recieved its ELSA airworthiness on Christmas eve, 2006. It has been my only route to the sky for the past few years since leaving the Arrow group. I have a 1000' home strip and hangar.
    Started getting interested in Avids recently, last month I went to visit Jim to see how they would feel and how I'd fit. Well, I'm a convert. An ELSA registered Avid Mk IV with Heavy Hauler wings (each with an extra 12'' length) came to me last month. Equipped with a Jabiru solid lifter engine that shows no signs of ever been overheated, Catto prop, RV-6A nose gear (from Avid), original factory 18" fuselage stretch, 193 hours total time airframe and powerplant. Possible future conversion to taildragger???
    Been spending some time reviewing old topics, looks like lots of good info and good people. I look forward to contributing where I can,
    Mark
    P.S. Anybody know anyone interested in a trike :).
