As Christmas approached I wondered if I would be able to get a chance to fly before the end of the year, especially since we got a foot of snow last week. I like to try to get a flight each month during the year, and since I don't plow the hangar, it rarely happens. It poured all day on Christmas and was 60 degrees, totally melting the snow. Today was 35 degrees, bright sun and calm conditions, a pretty good day for a flight. 
I got to the airport at 1:00 and plugged in my pre-heater for about an hour while I straightened out my bench. I strapped in, closed the canopy, and let the sun do it's thing. It didn't take long for the temperature in the cockpit to get comfortable. It's a bit tough to start when it's cold, but it fired up and in about a minute it was running smoothly. It's been over a month since I flew last, and it felt good to taxi to runway 32 after a 7 or 8 minute warm-up. 
The density altitude today was minus 1200 feet so my take off was really short. Climb out with the Remaster felt like I had an IO 360 under the cowl. As I climbed to 3000 feet, I was experiencing a bit of engine roughness, which is common for me when the OAT is below 40 degrees or so. I leveled off and applied carb heat, leaned the mixture, and within a minute all was good. I fly my Q2 with full carb heat and leaned when I'm in these conditions, and I'm very comfortable with this setup. The engine smooths out and runs strong with this setting. 
Looking out over the New England landscape the only snow visible was on the ski slopes on Mount Snow and Stratton, about 50 miles to the north. I flew west for about 40 miles and checked out Berkshire East, a very busy ski area during the holidays, and the parking lot was full. My grandson Jack was somewhere on the mountain snowboarding. I turned back east to return to KORE, this time with a tailwind. The sun was behind me on the return trip so it began to feel a bit cold, but still comfortable. 
It felt good to get out and fly today with great conditions and no bugs to clean up. If January is good I'll be up there again. 
I hope all of you and yours have a nice holiday season.... Dave D

Re: "Darting" to Left on Slow Speed Taxi

David J. Gall
 

Hi Jim,

 

Merry Christmas to you, and to all on the Q-List!

I retired from ATC four years ago, then successfully pursued my dream of being an airline pilot for three and a half years before the coronavirus put an end to it, which was for the best since the strain on family of such a foolish job was starting to show. (Whenever an airline job is touted on the basis of “per hour” pay, divide that by 4 to figure out what the hourly equivalent would be in any other job.) I’m still in CA, still mucking about with airplanes and such.

So you’re taxiing downwind at idle at 15 kts. with a tailwind gusting 18-26 kts. from 20 degrees to the right off your tail. Basically, your vertical stabilizer/rudder is at zero airspeed gusting to -10 kts. airspeed. Any change of wind direction to be more from the left off your tail is going to be changing the roll moment imparted by the wing dihedral as much as the yaw moment imparted by the vertical stab/rudder. I think almost any taildragger would behave similarly, but the Quickie main gear is known to be a little more responsive to roll coupling than other planes. Did it do anything similar on the taxi back to the hangar when you had a headwind? If not, I’d diagnose it as “Corbin flies his Quickie when mere mortals cower in the hangar.”

Well, I thought today would be the first day I flew with the new Lightspeed ignition.  My plan was to do a couple high speed taxi tests and, if all was well, then depart for a test flight.  However, when simply taxiing down to the runup area it "darted" left on me twice.  I don't think it was because my feet aren't awake from not flying.  It just seemed to randomly "dart" left.  

The pedals and brakes feel normal and there is no play in the rudder cables.  Could it be the left tire/caliper is grabbing but then releasing.  I don't know where to begin troubleshooting.

I had a camera recording but not with the tailwheel in view.  Here is the video in case you want to see the "dart" and have any ideas for me to look into tomorrow.  I included the startup just for fun.  Skip to 1:15 and 2:15 for the two darts before I decided to head back to the hangar.

Could it simply be wind gusts....they started picking up around that time.  My heading on taxi was 360 and winds were 160 18-26kts....

Love that last line, David.  It didn't do it on the way back but I also went much slower and cautious.  But I still think it was indeed the tailwind.  I didn't go back out today due to low-level wind shear on the surface and more gusting conditions.

Re: "Darting" to Left on Slow Speed Taxi

Corbin
 

Jim,

Yes, there was definitely a tailwind and it was gusting so it is starting to make the most sense this is what it was.  For low rpm's I got it down to 500-525 with it leaned out.  But my fear is that after landing, as I am slowing down, that it will die as I would still be full rich and not always remember to lean during rollout.  So I think I will need to increase idle rpm up to 600-650 so it is happy full rich.  Thoughts?

Hey Martin!  I was thinking the same.   Just checked winds for tomorrow and it’s only getting stronger the next day or two.  Direct crosswinds up to 25kts.  I’ll still try since it won’t be a headwind.  Low speed taxi work.  But will do again on a more calm day.

Well, I thought today would be the first day I flew with the new Lightspeed ignition.  My plan was to do a couple high speed taxi tests and, if all was well, then depart for a test flight.  However, when simply taxiing down to the runup area it "darted" left on me twice.  I don't think it was because my feet aren't awake from not flying.  It just seemed to randomly "dart" left.  

The pedals and brakes feel normal and there is no play in the rudder cables.  Could it be the left tire/caliper is grabbing but then releasing.  I don't know where to begin troubleshooting.

I had a camera recording but not with the tailwheel in view.  Here is the video in case you want to see the "dart" and have any ideas for me to look into tomorrow.  I included the startup just for fun.  Skip to 1:15 and 2:15 for the two darts before I decided to head back to the hangar.

Could it simply be wind gusts....they started picking up around that time.  My heading on taxi was 360 and winds were 160 18-26kts....

Thanks,

Corbin

Yep. Quartering tailwinds on the ground or landing can be interesting. My least favorite of all landings. I presume there may have been  some tailwind?

I think you’ll be fine. Good luck with the ignitions. You’re gonna love them. What were you able to get the rpms down to?

Good recommendations, Jim.  Thank you.  The first thing I started to do when I taxied back was jack it up and examine that left tire.  The reservoir is about 3/4 full but I will double-check that tomorrow to be certain.  Tires are at 42psi today but I hear some go with 50psi?

I will do as you guys say and try another taxi without a tailwind and then proceed from there.

Corbin--- Regarding your tire pressure. It is not the same, but on my Dragonfly , 735 lbs empty, I  use only about 30lbs. On my Super Quickie also. Makes the taxi  and landing more comfortable. On my Super Quickie, if I taxied on rough surface such as grass, it would dart all over. As for your swerving, go taxi a short coupled biplane in a crosswind and you will understand why you never see one taxi fast.

 Have fun----------  Chris
