Listers,
Give me a couple of days and I'll
get back with design details and more on in-flight results. Flew two
more rides yesterday, 2.4 hours total. I need some left rudder at all
speeds. I'll review "P" Factor material, do some careful measurements
and see if some of the problem can be shimmed out. I'll hold off
messing with trim tabs if there is another way.
At full throttle and stabilized
level flight the engine is turning 5200 RMP at 125 Kt indicated (no
wheel pants or gear leg fairings) I have a couple of ideas to try to
improve power that I'll work on as able. I haven't done an airspeed
check yet. The left wing is heavy but can be trimmed out. I'll wait
awhile before massaging the aileron trailing edge.
If the ball is centered, there is
no wing drop in the stall.
Cooling has not been an issue
either on the ground or in the air. I had about 12 hours ground
running and lots of taxi time with the tail up and down. There haven't
been any serious issues with the engine installation (yet!) There is a
pesky oil leak (or seepage depending on how anal one is!!). My hangar
mate, who teaches diesel mechanics at the local tech school, gave me
some die and a black light to locate the leak. The big one was the
stock oil dipstick allowing oil to splash out. Solved that with three
small "o" rings pushed on to the dipstick seal. There is still oil
seeping around the back (front in the auto) cover. At some point I'll
pull the engine and reseal it, but not now.
Yes Rusty, 13B nearly stock; 2.17 :
1 gearbox; EC2 Controller and Tracy's 68 X 71 Performance prop.
Stock oil cooler and a slightly modified Griffin radiator used by the
dune buggy guys with a Sirocco engine. Stand by for more!
Regards,
Gaylen Lerohl

First
flight today.
Congratulations Gaylen! The
temps sure sound good.
How about refreshing our
memory with some details of your installation. I'm guessing 13B, with
the 2.17 redrive and Tracy's old prop. What are you using for oil and
water cooling?
I'm also curious what your
empty weight and empty CG came out to. FWIW, mine is 1080 lbs, with an
empty CG of 76.0", which is pretty nose heavy.
Cheers,
Rusty (first engine run
today, DAR next Sat)
