I built a vane type shutter and couldn't get it to work as designed. I'm tired of fooling around with tape and having to land enroute to adjust it as temps warmup... Thanks Joe ________________________________ Message 2 _____________________________________ Time: 10:57:32 AM PST US From: "Joe Spencer" Subject: Zenith701801-List: Substituting .016 for .020 on the skins? My 701/912s/VG weighs 579# empty with strut cuffs and other cleanup fairings...it's a heckuva good performer; the takeoff and climbout when solo and light on gas is shocking. I can't imagine compromising any of that performance to the least degree especially for subbing 020 for 016. There isn't any reliability issue associated with the 016 skin that I'm aware of, the oil canning is a non issue...you get used to it and it tells you when it's not coordinated, and there was no difficulty handling the sheets by myself while building. Just clamp a 1x4 along the edge and pick it up and move it. Mine has a TXP, Encoder, Comm, GPS, paint and light simple upholstery...the only other things I allowed myself were the cleanup fairings that more than paid for their weight in reduced drag(or I would have removed them). It cruises 97 mph at 5000 rpm down low with the Warp Drive set at a thin 11 degrees. I don't think you'll find any of the heavy ones that will do that...not if the performance has been accurately measured. Once it's built so it'll stay together weight is everything else...well nearly so. 30# for thicker skin is huge and pointless Joe ________________________________ Message 3 _____________________________________ Time: 04:02:03 PM PST US From: "Les Goldner" Subject: RE: Zenith701801-List: Re: Controlling Rotax 912 oil temp I can hold the shutter anywhere from right against the oil heater (0-degree) to about 75-degrees away. In flight the only testing I did was at the two extremes, 0 and 75-dregrees, and noticed that the oil temps changed about 20-degrees F on a 50F day.

I could not open them. --- On Tue, 3/2/10, Les Goldner wrote: > From: Les Goldner > Subject: RE: Zenith701801-List: Re: Controlling Rotax 912 oil temp > To: zenith701801-list@matronics.com > Date: Tuesday, March 2, 2010, 4:56 PM > > > > > > > > > > > > > > > > I > can hold the shutter anywhere from right against the oil > heater (0-degree) to about 75-degrees away.
