 June 9, 2002 - A trailer pulled up in front of a simple but comfortable
   home in Houston.

   Lots of trails, tribulations blood, time, money, recreation,
 education,  fun,  friendships, anger, frustration, problem solving,
  sweat, pondering  etc....repeat and  repeat again and again.

   Fast forward (it did go fast)

   June 9, 2012<x-apple-data-detectors://1 - Ellington Field - A lone,
  very  nervous man  arrives at the airport shortly before 0900 hrs.
 Pushes onto the ramp the  contraption  composed of fiberglass, metal
 et al and the ingredients listed above. He  sits down  and writes a
 simple holographic (hand written) will and short note with  information
   to call "Mom" and work. Calls tower to relay intent via the phone.

   Preflights the contraption. Gets in, goes though basic Checklist. Cranks
   up the
   engine, which fires right up at about 0920 hrs. Taxi to Juliet. Calls
   tower to verify
   intent and to taxi to active, 35L. Taxis to Taxiway Echo. Checks temps.
   Pushing 195
   with OAT reading 95 degrees (geesh it is only about 0930 hrs).

   Cleared to take active and hold. Taxied out. Lined up castering
 nose wheel  down  center stripe. Cleared to take off. Added power
 and engine smoothly ran  up. Airspeed  coming in. 30 kts...50 kts
 ....60 kts, approximate rotation speed. Lots of  runway
   (9000 ft).....hold it....70 kts....72 kts... Slight pull on the
yoke....AIRBORNE!!!
   Leaped into ground effect. Screw this, pulled back on yoke and I am
   climbing. Jiggled
   the yoke a bit to verify control authority.

   Climbed to about 400 feet and turned right pattern to crosswind.
 The Dynon  altitude  and airspeed seem to be working. That's
 reassuring. Pattern altitude is  only 600 feet  and I was there
 already as I turned to downwind. Leveled off and noticed  the clouds
  were lower than reported and appeared on the ground. Also, noticed coolant
   temps had
   dropped to 190....but oil temps were flashing at me and had
 reached 225
   (synthetic  Royal Purple). Damn. Ok. Fly the airplane, the oil is
 not at not a  critical level. ,  but let's just finish the pattern
 and land. I grabbed my phone while on  downwind and  attempted to
 record some data but while I can hear the engine the video is
 awful....uh, in my defense, I was a bit distracted and way more concerned
   with
   flying. I called the tower and informed them I was coming in. I
 think they  were  looking out for me since as I turned to base I
 noticed the fire department  staged  just off the runways threshold

   I noted I was a bit far out on down wind so I stared easing over
 to turn  base. Wow. I  really overshot it as I blew by the runway
 and had to use full right  rudder to get  back to the runway. I wish
 I had had more rudder. In hindsight I think I  was not  using much
 aileron as I was cognoscente that I had no idea of stall  characteristics
   so I did not yet wish too strep a turn. I was able to get over the
 runway  and dump  some altitude as I got over the numbers and pulled
 power. Crap, I am fast.  I am lined  up and right on the numbers but
 at 95 kts. I come and touchdown and  bounced. Pulled  power to idles
 and settled down easily but fast at 90 and rolled out and  exited at
  Delta. The tower was clearing me back to the city hangars as I was exiting
   the
   active. I taxi back and noticed the oil temps had decreased but I don't
   recall how
   much, just noticed they were lower.

   I got back to my hangar and popped the door and shut her down. The
 engine  went silent  without any hissing or gushing.

   I called my mom.

   I am mowing informing the world.

   I did a walk around and did not see anything missing. I am about
 to pull  the cowl and  check things out.

   I did notice I did not develop a slight hand shaking until after I
 landed  and exited  the aircraft. ;-) Hey, how about that, it really
 is an aircraft now. Ten  years to the  day following delivery.

   Thank you for your support.

   You made me laugh Chris :)

   Congratulations. You are almost there on the oil cooling.

  Congratulations on a job well done!

 You are an inspiration to all us builders out there, thanks for your
 post, I'll be there someday hopefully soon with my Cozy MK IV 13b
 Turbo. Good luck to you and safe flying, congrats. James Ealey

 Ok, here is new information to me.  I posted on the Velocity list
 regarding my oil temps and was informed that oil temperature should
 be measured coming OUT of the coolers, not out of the engine like I
 have set up. This is just the opposite from the way the factory has
 the coolant plumbing run as the stock coolant temperature sensor is
 near the thermostat housing as it comes out of the engine and into
 the radiator.  I do not know where the stock oil sensor is located
 (if I did, I now forget) but Al G. and John Dibble state the temp
 should be taken for oil coming out of the coolers.  Heck, if this is
 the case, my oil may be quite a bit cooler than I was thinking.
 Opinions please.  It should not be too difficult to add a sensor to
 where the oil enters the engine.  Don't know if the Delta will be
 much, but perhaps enough.... What say Ye? Chris

 You can learn a lot by having both.

 Coolant radiators are designed for a 10*F differential across them. Oil
coolers I would expect to be similar. Conventional petroleum oil begins to
break down at 250F. Synthetics are quite a bit higher. More like 325-350F.
