I promised to report my indicated water temps next chance I got. Here are some samples:

 

OAT(F)        Delta T (F)

69                    23

66                    19

68                    10

75                    14   

65                    15

75                    7

77                    12

 

All figures are in cruise at 8,000 to 10,000 MSL.  Last reading was in climbout, but not much difference.  I really can't explain the range of readings, but that is what it read!

 

I adjust the cowl flap to keep the oil and coolant temps in the 190's.  This is a compromise between the 180's I would prefer, and the turbulence off my cowl flap at more open positions.  (I know - there has to be a solution, but right now I am just enjoying flying!)

 

This was on the way to and from the Land of Enchantment RV Fly In at Las Cruces.  There were close to 175 RVs there, and I was ONLY non-lyc engine in the crowd (that I know of).  Your rotary ambassador removed the top cowl for the event, and needless to say, it drew the usual crowd.  I am always amazed at how many are interested in this engine and follow this list!

 

Sure would like to be at Shady Bend, but work keeps getting in the way of the fun stuff.

PS  Had a chance to take a good look at the rotary powered Dyke Delta.  I forget the gentleman's name, but he is deep into solving cooling problems.  He has replaced the evaporator cores with stacked aftermarket oil coolers (I think that is what they were), and is modifying the cowl inlets and outlets searching for some airflow.  The "lifting body" configuration of the Dyke presents additional challenges in this regard!
