Perfect RC morning XK A430 (6 min 3 sec)


It was supposed to be windy !

My back kicked me out off bed around 6.30am ... So after hitting the porcelain , I went to get a drink ..
Glancing out the window , Blue Sky and a perfect chalm ...

So I grabbed the XK A430 and went out for my morning walk / fly / walk back home .
As soon as I closed the front door on my return , the predicted wind came up .. And the wind blew for the rest of the day .

Still rusty azzzz can be !

But I did try a fair amount of inverted action ... It's tough when for two months ( quick sharp lock down ) your under 22 hour house arrest and no outdoor activities are permitted ...
I mean , just how much of a threat is a guy standing in the middle of a football field flying a Micro Electric Plane by himself ? ( Verboten )
Such is life in a Convict Colony ...
And all the rubbish Stalin wanted , Dangerous Dan is making a reality ! All Hail Ming the Merciless !

The takeaway, OpenTX and frSky!

After experiencing the OpenTx world on my DLG, I’ve started the process of migrating from Futaba. I installed a gr8 ACCESS receiver in my Supra Electric with full telemetry. Although the Supra still experiences rare and unresolved launch issues, it seems to be flying fine with the new radio and receiver. I setup an altitude alarm to trigger at 400ft. Now there will be no doubt about flying within limits of the field!

My Alpha 2m was just migrated, will be flown this weekend. My new Pulsar 4m will be setup with the same when the new receivers arrive. I also acquired a Explorer 3 electric, waiting receiver installation.

Nothing but good things to say about OpenTX and associated hardware.

3 Days left for OCTOBER, and then we start into the fall season...

Well, today was sure a hot one. 94 degrees with some humidity...not a lot, just enough to make you sticky and sweaty. Big puffy clouds and plenty of sun! There was a warm breeze coming out of the south-west...it was nice... But the more important part was the maiden of my new Protos Nitro. This thing is light! It feels tail heavy holding it, but the balance is spot on! I looked everything over one more time, before powering it up for flight. Checked the controls, filled the tanks, past the point of return...aka just going home due to the heat!

Maiden Flight

I set the throttle trim on the transmitter, plugged the glow igniter in, and spun the motor! I wasn't sure where the motor was going to start on the trim, and I had to give it a bit more trim. The O.S.105 popped off and sounded good. I walked out to my flying spot and set it down. Ok...last radio check. I spooled up the motor and while the blades were spinning, but not quite fast enough for lift off, I bumped the cyclic controls to verify proper direction, as well as the tail...everything is good!

Added more throttle, and I'm off the ground! This heli is even light feeling in the air! Need to make and adjustment to the agility on the cyclic...it's fast! The tail gain was a bit too high, it wagged in right hand turns. It buzzed some during high speed turns. No problem! I can turn that down in the radio...Jeti integration, gotta love it. I...Continue Reading

A hypothetical German experimental aircraft from WWII.

Essentially a gyrocopter, the blades were variable pitch. For take off, the Strahlrohr baffles in the rear jet wash box behind the BMW engine would be raised, directing the exhaust onto the rotor to spin it up allowing vertical take off. Once the rotor was spinning, the baffles would be orientated horizontally and the jet engine then provided the forward thrust as normal.

While hacking 60W lightbulbs is a cheap way to get bright white light, 100W RGB lightbulbs are absolutely a waste of money for making colored light. The rated brightness on these is for white light only. The colored light is a different mode & uses a small number of dimmer RGB leds on 13V. The white LEDs run on 140V & can't be ground down to run on 12V. The 2 sets of LEDs aren't used simultaneously. The cheapest way to get colored light is the good old snail mailed COB.

New toy..HP DesignJet T 520 36" wide roll feed plotter. A friend of mine inherited 5 of them from a guy that repairs copiers, plotters, etc.....SCORE !....Hooked it up last night ...ordered new ink cartridges. Now I can plot what I want, when I want it, and not have to pay OfficeMax/Kinkos a king's ransom per sheet

After a wait for some good weather, my Albatross profile control liner flys at Breezy Hill.

This is a demonstrator kit, built by Stan Fronabarger at Vintage Performance Model Airplanes. He also markets a Newport fighter of the same size in case you want an antagonist for your German Fighter.

This model is flying behind a Fox .35 Stunt, on 60 feet of 85lb Spiderwire, and is relatively fast on that combination...having no trouble packing its two GoPro cameras around the Crop Circle at Breezy Hill.

Not so long ago - the likes of Hobby King and similar had budget as well as more expensive gear. We all break props .. need wheels ... etc. etc.

But now you go online and its hard to find those items we took for granted ... or the shipping is just crazy.

I need 4.1 x 4.1 R props as pusher ... HK had loads of these and similar but now ??? Nothing.

I found APC style on another site - but for ONE prop - they wanted $17 shipping .............

In the end AliExpress came up with what I wanted but still not exactly budget priced.

🧐Yep Les Amis,
Une ENNNORME FRUSTRATION !!! J'en attendais tellement de ce nouveau cinewhoop d'HGLRC, le VEYRON35 CR Pusher ! Je le trouve superbe, très bien conçu et notre premier test en vol à vue était réellement prometteur. Puis, les dieux du FPV en ont décidé autrement ! LOL. Sans aucune raison ou modification, du jour au lendemain, le problème est apparu... Nous avons tout vérifié bien sur, du hardware au firmware, sans succès. Après un échange avec HGLRC sur ce souci, Eric me renvoie donc une frame et une carte de vol car pour lui, c'est un défaut du gyro. Donc nous testerons à nouveau bien sur ce superbe engin qui le mérite selon moi. HGLRC est un constructeur sérieux et à l'écoute donc nous ne lui en tiendrons pas rigueur même si ce jour là, la déception était au RDV ... Prenez soin de vous (et des autres) et merci à tous pour votre soutien .

Introduction



A full-scale sailplane pilot told me that the yaw string is the most important instrument in a sailplane. It's hard to believe that it's more important than the airspeed indicator, altimeter, or vario, but he was very clear that the yaw string is important, even though it's just a piece of yarn taped to the canopy. Apparently without a yaw string it's hard for a pilot to tell if his glider is making a coordinated turn, meaning that the fuselage is aligned for minimum drag as the plane turns or circles. So if it's difficult for a pilot sitting in the cockpit then it seems reasonable that it would be difficult for an R/C glider pilot on ground. The yaw sensor is meant to serve as the equivalent of a yaw string for radio-controlled sailplanes.

This is a project that I started a couple of years ago but didn't do much with it until recently. It works with OpenTX / EdgeTX radios and telemetry receivers. A voltage sensor is required, such as the AIN2 input that many FrSky receivers have. When working in conjunction with a Lua script it will produce beeps to indicate how far from center the fuselage is aligned and in which direction. An adjustable "window of silence" stops the beeps when the sensor is aligned with the fuselage.




Next: Building a Yaw Sensor

Each build has its own needs, but here are some essentials for anyone building balsa scale models.

Hobby knife, microsaw, metal straight edge, scissors, rotary tool, screwdrivers, level, drill, and also cutting mat, sanding blocks, Titebond II, CA, straight pins, adjustable light, and a work bench.

As an addendum, let me add some items essential for some but not all:
:: an 800 watt soldering iron was essential for landing gear. I got it for only $10 from a lady who worked on stained glass
:: canopy glue is incredible stuff
:: an iron for Monokote
:: CorrisionX for float planes

Whew! What did I miss?
