Matt,
My condolences to you and your family. I am so sorry for your loss, it is a loss for all in the C/L community.

John yes it will uncover first,  but only seconds before the tank is empty.  This gives you a very brief run up and cutoff-not several laps of high speed screams and burps.  It gives you the chance to exit any maneuver (you should have stopped doing anyway).  The way you describe your current method of plumbing is common and I never understood it.   Once the uniflow is exposed-at maybe half a tank-it is no longer a uniflow tank.  It becomes pure old fashioned suction feed and you should expect the engine to respond by going leaner as the flight progresses.  I've never been a fan of plastic tanks either because you cannot really control the accurate placement of the uniflow tube as you can with a metal tank-weight be darned.  Some of this becomes nearly moot where you are running a Schnerle something screaming in a full-throated two cycle anyway.  But IF you are wanting to run a smooth 4-4-4 or 4-2-4 type run you should have the tank working to facilitate that.  If you happen to be flying FAI the last few seconds of fast run up and quit helps you get that one full lap of glide before touchdown which is harder than it seems sometimes,  especially in the wind.

Dave thank you for that explanation/description. I'm not sure that I am completely understanding it so this question may not make sense. My question is : If the uniflow line is inboard of the fuel pick up wont it uncover (not be in the fuel) sooner?

One reason I am asking this is because I recently came across some plastic tanks where the uniflow line was soldered to the fuel pick up line on the outboard side of the pick up. I haven't tried one yet.

I have been using a fixed uniflow line running about 1/2 of the way back in the tank and ending near the outboard wall but am always looking for a better mouse trap.

Sanded the edges to remove the excess silk span with 320 grit paper and then brushed on another coat of clear.  I'll put on a total of 3 coats of 50% thinned clear before spaying with primer.

Applied silk span to some parts by wetting with a spray bottle, lay it on the part and brush on dope.  Then rub with finger to get good adhesion.

Those are some really neat videos!

Thank you,

Open Forum / Best of the Best! Stunt Flights from 2022 World Championships
« Last post by AMV on Yesterday at 07:10:25 PM »
Hello everybody,

With some help from Niklas Löfroth and with his permission to use the videos he recorded at the contest, I hereby present the same videos with motion traces and Augmented-Reality geometry including the Nominal Figures of each maneuver per FAI F2B Rules.  The videos were traced using a pre-release version of VideoF2B software, originally conceived and implemented by Alberto Solera in 2018, as announced here on StuntHangar.  I took great interest in the project, and have been actively developing this software into a user-friendly product since 2020.  Version 0.6 will be officially released very soon.  Watch this other thread for those news.

In the meanwhile, enjoy the results of our collaboration on a global scale!
The videos include flights from the top 15 F2B pilots in the world in 2022.  There will be a total of 45 videos.

I have posted Round 1 of the Finals so far -- 15 flights.  More will appear in the same playlist in the near future as time allows me to process them, one round at a time.
The scores from the contest are publicly available here.  Note that I am presenting the flights in the order they were flown, according to the F2B Fly-off Schedule.

With no more ado, here is the VIDEO PLAYLIST.

I'll be happy to entertain any questions about the video tracing process and the software in this thread or in PM/email.

Cheers, H^^
-Andrey

The site wants to add a manuals extension to my browser.  Is this normal?  Is this OK?  Just nervous and don't want to mess something up on my computer.

      It may have to do with what version of Adobe you have on your computer. I have never gotten that message on that site, but check it out. I have had little to no problems with Outerzone. They go down from time to time so it seems like there is some one always watching and working on the site. My computer shows the site connection as "secure."
    Type at you later,
  Dan McEntee
