For all those of you at the recent RHV fly-in who asked me to send performance information, here is a recent leg:

 

Salem, Oregon (home of UPS Aviation Technologies) to Denver, Colorado’s Jeffco Airport.  Direct mileage was 874 nautical before take-off, but I would estimate that I flew at least another 75 to 100  miles because of terrain (I did not attempt direct, rather went across Southern Wyoming) and in deviations due to terminal conditions in the Denver area.  This was a non-stop flight at 13,500 (thanks to the Mountain High Oxygen system!), with full throttle and 2400 RPM.

 

I started with direct to Ogden Utah, then, after I was past a couple high mountains (the terrain feature of the MX-20 is awesome!), changed to direct to Rock Springs Wyoming.  As weather developed, I went direct towards Casper, then changed to direct to Cheyenne, then direct to Denver when the weather began to dissipate.

 

Total time enroute was 3 hours 50 minutes, with less than a 15 knot average tailwind, and I landed with 14 gallons of fuel (I developed a partially clogged injector on this leg, so couldn’t lean as well as I would have desired).

 

One thing I forgot to mention at the RHV fly in is the gascolator.  Don Barnes has, on his site, the pictures of my change compared to the Lancair prints.  I went to a Salvage yard and bought a used Cessna gascolator (make sure you get one with a high enough volume capacity).  We then installed it in the same place as the plans and ran a push pull cable to drain it.  You will have to remake the cooling shroud as the anodized one from Lancair will not work. This is an absolute must unless you relocate the gascolator…..one cannot drain it on preflight when installed per plans.
