Another first flight.

Happened today. Winds were kind and I took the chance. The 25 min flight
went fine, took off smoothly and touched down nicely without a bounce
inspite of 7kts cross wind.
There is some tweaking to be done; radio worked intermittently - lost
communications with traffic, but the standby airport rescue crew covered
for me; the engine was near top temperature limit at climb; and oil
temperature was high - at only 70F outside, maybe I need bigger oil cooler for
the Franklin? Any Franklin experts out there? Recommended oil cooler size?

Congratulations. Feels great, doesn't it?

Welcome back to Earth, Paul!

Od curiousity, what did you build?

Congratulations Paul !

Let us know how the propeller work when you don some more testing and
tweaking.

From all I've read Paul, air cooled engines in rear mount position are
tough to cool properly. Does your design have actual scoops for the
cooling air, or NACA type openings?

By the way, congratulations on your successful first flight.

That would be an SQ2000 canard, Richard...

I'm behind the curve on that one, RIchard.
Do you have some pics posted somewheres?

Yes it does have scoops - with downdraft. But CHT's were not too bad.
Near limit at climb and only about 320F in cruise. Its the oil
tempereature that is of concern. Just found out that my oil cooler,
Positech 4211, is too small for the 220HP Franklin - Positech
recommends 4219.

O-Tay! Thanks Ron.
I didn't recognize the name, but that shape certainly looks familiar...

Way to go, Richard Riley!

Actually it worked fine for the short operating range I used this
time. At takeoff it had real good punch (or maybe it was the combo of
220HP engine, electronic ignition...) . And when I reached about 110
kts I had to increase the pitch to keep it from over revving. The
adjustment was smooth and short meaning it had plenty of pitch left
for higher speeds. I kept the RG down and went no more than 120 kts.

BYW the Dynon EFIS-D0 worked well too - agreed with the backup
horizon, speed and altitude meters.

Good to hear it worked well.

I will make a Clarification;

Don't get the analyze I made earlyer the wrong way,

I am sure there are other props that will be more effective, even an fixed
pitch prop can be better at specific design speeds, but the overall
performance will gain from the adjustable prop, specially on high
performance plane like this beauty, it is all about speed range.
