All,
I attended a recent EAA webinar on test flying your homebuilt, it was very
good. You can view a recording on the EAA site. Johnny White was the
presenter and he sent me the following regarding breaking in a rebuilt
engine. I'm not a mechanic but it could be some useful info for those in
need.
Hi Jack
Thanks for the comments and I am glad you enjoyed it. It is best to run in
with a Test Club prop in a cell but many an engine has been run in on the
ground and can be done with some reasonable precautions. Rent a Test Prop
if you can or a fine pitched prop so Rpm will come up to about 2200 static,
into a good breeze, keep them short, Run long enough to get oil temp up
above 180 if it will.
Three 15 to 20 minute runs are sufficient. Check the Oil Screen / filter and
drain just a little oil from the sump (Quick Drain installed) after the
third run and it has had time to drain down any particles that will settle
to the bottom of the sump to check for metal. Check the lower plugs for
contamination and condition of burn. Have a CHT gauge or use a Pyro meter to
check for the hot cylinder and just don't let them get over 375 degrees.
Fuel starvation is still the killer and the big risk.
In the air run it at 75% for 45 minutes at a time and cool very slowly with
small, slow throttle movements. "Step" down your power slowly and smoothly.
Power on descents from cruise altitude are a must. Leave power up and let
speed build and cool the engine gradually.
Good luck with you venture and let me know how it goes or if you need any
help I will be here.
Thanks again.
Fly Safe & Smooth

Congratulations on the move. Your plane looks great. One thing did strike me
as being quite funny. It is when I look at your fuse pic. All I see in that
photo is a strange landing gear configuration. Do you think all three of you
can run fast enough to get it airborn?
Congrats,

I guess what I am trying to say is that it is very Fred Flintson like.
Still laughing here in So CA,
