RE
ynon Oil Temp Sensor fix and HOBBS???
My, My how time flys (pun intended
) July 15th 2009 BUZZ (N74BZ) had his first flight and already 2nd page news on the Van's Hobbs. As mentioned in the first flight thread Buzz
http://www.vansairforce.com/community/showthread.php?t=45686&highlight=Buzz
flew straight and true but.......erratic oil temp on the EMS D120 and a persistent oil leak have been a minor problem during the intial flights.
Yesterday flight proved all is well..... Lower elbow on the oil cooler was given a full turn...oil leak gone
Removed the Dynon oil temp sensor (sensor body to case ground)and installed the GRT's oil temp sensor with it's own wire to fire wall ground block. Oil temp now is rock solid.
Buzz has 13 plus on the Hobbs, engine runs great, Grin is still hard to take on the facial muscles
, ready to install the complete interior, put on the wheel pants/fairings, and look forward to being out of the Phase 1 jail.....![Roll eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Engine stats couldn't be better. Oil temp 180, cylinder temps at or below 400. (Bob Looper the fellow that ran the engine in says I am babying the engine. He said that break in will take place sooner if I lean it out at 75% power and get those CHT's in the plus 400 to 425 degrees F area. Buzz will start on the first blade unless HOT after flight and then the old hot start procedure must be used. I installed a pressure plenum cover instead of the tried and true rubber to cowl style, which I think is the reason for the good oil, CHT temps even in the HOT desert air.
The only regret is not getting the plane totally painted but that minimal pain is soothed by seeing BUZZ FLY!!!!!!!!
