The only change made was to remove coolant therm. & install temp/safty wired bolt/washers to block by-pass hole, temperary because we may want to use therm. in winter, Michigan gets cold. Temps on ground never went higher than 210 F, at 5900 rpm max. tied to full sized chevy truck, brakes will not hold aircraft above 4000 rpm. David ( outside air temps during flight were 82 F )

Congratulations, David. I hope to be following you soon. Are you able to cool on the ground? What did you do to improve the cooling between the two flights? On 08/30/2012 10:48 PM, hoursaway1@comcast.net wrote:
Thanks Mark, it was kind of anti-climatic for the others on the ground because they already saw that last month, but for me seeing the temps coming down at about the same stage as Terry saw them still climbing was comforting. I'm setting up a video camera to record the panel so I can focus on flying for now until I get more comfortable. We have a 100 mile radius to work with & I asked for & was granted a crew member during the flights that computer tuning will be worked on. Tryed to get a stewardess also but FAA said no. ???? Yes I read Ed's procedure for takeoff & our sys. is very similar so will use for next flights. Terry is a member of our EAA Chapter 55 here in Mason MI, his dad just flew his 400 th Young Eagle. ( where is that stewardess with my Margarita ) David.

Congrats!!! Job well done. Terry Lutz... WOW!
What was the OAT? I start to get nervous when my coolant temp goes above 200 F. No reason to climb at WOT if not needed and OAT is high.

First flight for me anyhow not for the aircraft, Terry Lutz ( AKA;; world renowned professional test pilot, flew in from France to do the First, First flight ) Temps went;; coolant 221 F max, oil 210 F max, on full throttle clime out up to 2000 ft., powered back from 6300 rpm to 5000 rpm/135 mph indicated, push the nose over to level off, pulled power back to 4500 rpm ( made no prop pitch changes at this time ) temps went down to;; coolant 195 F, oil 190 F, this is without therm. & bypass blocked, also would like comments about sealing around sides of both radiators, we saw the extra fins there so we allowed air to pass through that area, may install a temp seal & recheck data points next flight. Then possibly install venting openings in bottom of cowl to let more airflow out quicker. David R. Cook RV6A Rotary.
