Les
Understand the shutter works well for warmup...can you precisely control
the temp in flight? 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

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

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.

Les, could you forward the pics of the oil cooler baffle to me? I could not open
them.
