REFLECTOR: Test flying update

[David Rene Dugas]

Thanks for the update. It can be boring but it can be exciting. I recommend you make a long list of emergencies and write out the procedure you think best. Now us the time for that. Then practice and plan: engine out, oil pressure loss, loss of a brake or tire on take off and landing. What will you do for fire?  Exactly!  How will you handle a door up, what will you turn off if you smell smoke,  wing tip vortex, loss of stick control of roll(practice rudder control). Can you knife edge it to lose altitude so you don't miss an emergency landing.  practice rudder control just above canard stall if you had to land off airport you'll be a pro. The list is long but you have time. Please preflight really well our planes vibrate too. 
Best.

Great weekend here in New England and I was able to get out for ~4.5hrs between yesterday and today.  I suppose I could have done more, but it is getting awfully boring flying around my little box.  But, here's where I'm at.  I've got 31.5hrs in so far, so not far to go.  I've had a few issues, but nothing too major.

I had been fooling around with oil separators and ended up putting too much restriction on the oil vent which caused a few leaks to pop up.  I was able to get the leaks taken care of and now I vent my oil line into the exhaust.  Its not really a permanent setup, but it works ok.

I found the take off roll a bit long and had been thinking about sending it back for re-pitching, but didn't want to be down for a month.  A canard owner on the west coast had an older Catto prop that would fit my left-turning engine, so after a rather long process we were able to identify it as a 64x76 and I had him ship it out to me.  I just started using this prop and it is working well.  Its shortened my takeoff roll and I still have about the same top end.  At 10,000', running 50F LOP, I get 150kTAS using 7.5gal/hr fuel.  That's about what I was getting with the other prop, as well.  The 64x76 prop is an older Catto design, so I think I'll get my original, newer Catto prop re-pitched to something similar to this as I think his new design is more efficient and may get improved performance.

After only ~15hrs on the plane, the pads were done and the rotors were deeply grooved.  For ~$350, I ordered the parts to beef up the Matco 600XT's I had to the 600XTE which are really just a thicker disk and slightly different pads.  So far, these have worked well and the pads and disks are wearing normally.

Just after the numbers I start to turn in and drop altitude as fast as possible.  This can lead to faster speeds on final if I get sloppy.  On tight fields, I do a longer final to make sure I can get good speed control.

It was a bummer, too, as I'd been traveling for a couple weeks, the weather was perfect and I was hoping to bank some hours.  10min after take off, the alternator light started to flicker, then went on solid so my weekend was ruined.  Don't really know why it failed (stator was fried) - its a 60A one that should have more than enough power to handle the loads I have.  They shipped me out a new one in time to fly this weekend, tho.
