A flight with my Millennium Slow Stick X airplane designed by James Karpy.
It's been on my wall for a while and I figured it needed to be flown.....  So here's a little flight with it.  About a 46" wingspan.

My normal head camera setup with the Lumix FX78 but I remembered to set the ZOOM in a little bit before recording this time...
Landing a bit better for you pgandy?  <grin>

I flew the SuperCub the other day and I guess I got a bird riled up at me!  He was really coming after me for a while....  He was hot on my tail.....  Check out about 4:30 ...
Music is Barnes & Barnes  "Napnoop: the Middle Aged Men Suite"
This is a different park than I normally fly at and the field is quite rough.  But that's no excuse - I just botched the landing.

Grizz - thanks.  Yep - that bird was tailing in right on my six, huh?  If he'd had guns I'd have been a gonner for sure.  Actually I was a bit worried about him doing a *real* attack.  I knew an old timer once that said he'd seen a bird take down an RC plane more than once!

Here's the same flight from my head camera view.  It really does show the bird action a whole lot better.   But I edited out a bunch of it.  The music is by a group called Inde' Skies.  My childhood buddy, Stephen, was the keyboard player as well as several other instruments.  Unfortunately they are no longer together.  I think one has passed away.  But I really do wish they would get back together and make some more music.

This field is rough - but that's no excuse.  I just plain botched the landing.....  That bird was sure after me though!  Even when he "broke off" his attack you can see him  hovering around at altitude - keeping an eye on things!

A flight with the EasyStar & GoPro on my home-made panning camera mount @ Whiteside.  It was a rather dark, cloudy day.  This park has a whole lot more obstacles to watch out for - trees, utility poles, lines, etc...  I feel like I'm flying out of a bowl at this park.

Well, I got that F3A rebuilt and took it out the other day to try it.  This was the third flight of it.  The first flight was a "fatal" crash.  The second flight was marginal but I did manage to bring it back.  And then this flight.  Same d***ed thing happened on me.  Would flight straight and level fine.  Do rolls fine..  But try a split-s, loop or any maneuver where it's upside down for any length of time and it would start corkscrewing.  Once again - a simple loop and it went weird at the top and down she came.
I know I'm not a great RC pilot, but I'm not THAT bad.  I really think there's just something strange with the design of that kit.  I'm done with this plane.  Was a costly lesson too.  At least this time I salvaged EVERYTHING off of it except for the airframe and the broken prop.  The motor was intact, servos, speed controller, battery, etc was all intact and reusable.

I've learned NOT to stop and worry about a bad crash but to get back into the air ASAP.  If you ponder on it for very long it messes with your head and really can destroy your confidence.  So I had my SE5a in the Jeep with me and immediately took it up for a flight after the crash.  Bounced the landing a bit but managed to taxi it right back to me.

I have no experience with this but from watching your videos it looked to me like it lost air speed and stalled when you attempted the loop, as if it didn't have enough motor to take it over the top. I'm not saying you need to be told but I thought you might want to review the Wikipedia article on the subject and consider whether that might be the case. If so, it could save you some agony and expense in the future.

Thanks Ron.  Each time I experienced the issue it would get to the top and corkscrew to the right.  And, yes, after that it lost lift.  It should have tracked straight and true though.  I don't have that problem with my YAK-54 - it tracks nice and level at all times - at least for me so far.  But I haven't flown it a lot.   I have encountered that issue with my GWS F4U Corsair.  But I quickly learned it was because I was mounting a 808 keychain camera out on a wing.  That made one wing a bit heavy and it would tend to corkscrew in a loop.  I don't run a camera on that plane anymore but did have to tape a little weight on a wing to get it to balance out.  Now it tracks nicely.  But it's a LOT easier repairing foam than these built-up wood planes.  ha ha..

This is the motor I was running.  I'm sure glad it survived because it took the brunt of the crash.  And the rare earth magnets have really taken a jump in cost lately so these brushless motors have really spiked in price.

It's 220 watts max.  I checked it with a wattmeter on my setup and it was pulling 190 watts full throttle.  It had plenty of power as I never flew it more than 1/2 throttle on the whole flight.  So if it required more power it was pilot error - not the setup I think.  The problem was that once it went off-level the wings started losing lift (stall - like you said.)  And I wasn't a good enough pilot to correct it with left aileron in time to keep it from spiraling in.   I still think it's a issue with the design - maybe in the airfoil itself.   It should NOT have done any twisting (roll) without me giving it left/right aileron.  It should have stayed level.

One thing I did do wrong however was try that loop too low.  I should have taken it up a lot more.  Then I would have had more time to recover.  The old adage "altitude is your friend!"  Regardless, if it was that finicky I really wouldn't want it anyway.  It's not fun to have an airplane that is so touchy you constantly have to worry about it acting up and having to correct for it.

All part of the hobby.  Without the risk of crashing there would be no challenge in flying these things.  And with each crash you (hopefully) learn a bit more.  Live & Learn!

Thanks for the input....  I appreciate it.

Since I've shown great skill recently at crashing $110 wood model airplanes (grimace),  I thought it might be prudent to try a $40 foam model again.  So here's a build of a GWS T-6 Texan.  This is the EPO foam design.  It's really tough and resilient foam but paint doesn't stick very well to it - although you can use any paint you want without worrying about it melting the foam.  Epoxy doesn't stick to it well either.  I used Gorilla glue to joint the wing halves and on the stiffeners.  UHU-POR for most everything else with a little low-temp hot glue here and there.

GWS made some nice improvements on this model with REAL wheels - not those cheesy plastic ones.  Nice snaps to hold on the cowling.  Nice, large battery compartment.  Better instructions.....  There were some minor problems but nothing large.

Now - will if fly?  And can I fly it without crashing it?

One of my favourites, although your model reminds me more of an SNJ being yellow.  I hope it flies as good as it looks and that you have better luck with this one.  For future models you might want to check on the insignia placement: on top of port wing and bottom of starboard wing, and more outboard.

Thanks pgandy...
I don't really try to color or mark per scale though.  More just what I feel like at the time.  Good example - the yellow wing tips on my Corsair.  As for this color scheme and decal locations - it was taken off of one of GWS's suggestions to some extent.  I didn't put the numbers on though.

But regarding T-6 Texans and their coloring - the combinations are almost endless....  Here's a site with hundreds of them in all kinds of configurations...  Sliver, blue, red, orange - you name it....  Didn't see any black cowling though like I did on mine.  I'm thinking I might stick a "scorpion motor" decal on the cowling on my model.  They give decals with the motor.  I'll bet that's sure not standard issue or scale either!  ha ha....

I'll leave it to the pros to know all the exact markings and locations.   I just do it for fun.  Like the machine gun is wrong on my SE5a - but it works fine for me!  ha ha...
I appreciate the feedback though.....

Yep - that's a really cool site for airplane pictures.   They have thousands of photos of planes from commercial to military to private with about every color and markings imaginable.....

Yeah - that guy is either really brave or really stupid.  He did his first flight over the Swiss Alps about 3 years ago.  Has flown several since including crossing the English Channel.
I'd have to seriously invest in some "Depends" to try that.  Guess that's why I do my flying while standing on the ground.  I walk away every time....  ;-)
