Form Andy Kunz:

"DSMX allows only 10 channels in 11ms mode. 4 channels (2,3,4 and 6) are at 11ms, and the remaining 6 channels are at 22ms.

If you change to 22ms mode, then you have 12 channels at 22ms and 8 channels variable (22-88).

It shows this on the Frame Rate screen display on IX and NX radios.

Face tracker 1 (8 min 14 sec)

The decision was made to transfer to using a face tracker instead of manually pointing the pole cam. Manual pointing would override the face tracker if the remote control was powered on, but it was expected to disappear. The lion kingdom found itself running more often without powering the servo, since carrying around the 2nd paw controller was a hassle. It was manely used for pointing the camera at the lion instead of viewing anything else. The most desirable shots were tracking the lion during a turn, but this wasn't possible with manual pointing.

The ideal tracker would run a pose tracker & face tracker. This can run reasonably well on a 4GB GPU. The face tracker would pick out the lion & the pose tracker would track any visible body part when the face wasn't visible. Unfortunately, the embedded GPUs of the past were all discontinued so the lion kingdom settled on just the opencv face tracker on a raspberry pi 4B.

Opencv face tracking is split into face detection & face recognition. Face recognition goes at 3fps while face detection goes at 7fps, so just the largest face is tracked. There is an optical flow step which keeps tracking the same face for a short time if a larger face appears. Optical flow works better at higher frame rates, but the best the pi can do is 7.8fps. Further optimization for slower modern confusers involved scaling down the video to 640x360.

I have been given an old Flair cable tensioner, previously I have just had adjusters on each cable - has anyone any experience of the Flair device or similar and do they work?

we hear about DSM2, DSMX, and so many other alphabet soup letters...
but, what does it mean?
what we get from that?
i have found some links to threads about it and i would like to bring some to see if you learn what is this all about.
for instance:
more specifically:
this in particular explains it well what the letters used by brands:
here we find links to most brands:
and here he tells us which 1 is better: isnt?
but then we get the final word about all of it here:
" all modern model RC systems to the best of my knowledge are both FHSS and DSSS.
They describe different parts of the generation of the RF signal.
FHSS is the scheme by which the frequency hops around the 2.4 band to minimise any chance of swamping by other 2.4 signals from powerful transmissions.
DSSS is an encoding scheme on those frequencies that optimises the signal to noise ratio.
Combination of the two gives the best chance of a long range reliable control link.
The last paragraph of the David Buxton document "RC Spread Spectrum Demystified” summarises it all:
"Our radios use FHSS, which is modulated using DSSS, which is modulated using CDMA, which is modulated using frequency or phase...Continue Reading

Got the wings and feathers hinged and assembled. Wing is a modified KFm-3. Steps are at 66% and 33% with (2) 0.156 sq CF spars. Leading edge was beveled and sanded, and the LE tape will soften the edges. A standard KF-3 is 50% and 75% I think....At any rate, a 50-75 KF would get into the ailerons...It wouldn't work. Besides I've flown this wing before, on this airplane...she flew just fine

I cut this little girl out several months ago with the thought of building her again.....however, the demand for Einzpfeils and StealthStreams took precedence, plus a couple of balsa gliders. Probably going to color her the same as before (see pic). I still have to cut and shape both the canopy and the nose block, but that won't take long. I'll have the wings and the feathers assembled shortly

Since I've had enough of gliders for awhile, I'm going back to stand-off scale warbird foamies .....(3) to be exact...An S-3 Viking, a CF-100 Canuck (already cut out), and an SU-25 Frogfoot. I've got a drawer full of fans and ESC's....In prep for that, I cut some control horns, this time out of 3mm light ply...the one's I cut out of 1/16 were just too fragile......and I can paint them to match the color scheme of the aircraft

My wife said putting puzzles together might help my mental health. Good to know. I think assembling tightly-cut forestry products into a work of art is a brilliant idea. This puzzle is called DW Hobby’s Hansa-Brandenburg w29. 😉

Okay guys,

Today was just a magical morning in Central Florida. Cool at 60 Degrees F and Zero wind and with a Large BLUE sky to enjoy!

I arrived right at 9:03 am as I didn't want to compete with the early birds at the Club for a turn. I needed the sleep and rest after almost a full night of working and preparing my new member of my fleet, the 2000mm wing span Cessna 182 giant.

The model leaped up with just 4-Cells using that 840Kv 35mm brushless outrunner motor and a bank of parallel, 4-Cells, 4,000mAH, 40C, Lithium Polymer pack place way up front. I replaced the test receiver (Spektrum AR6200 + SAT) - to- the (Spektrum AR8000 + SAT) and dual power feed from the CASTLE CREATION BEC PRO. Reason I needed the AR8000 as it has enough ports for the Dual Feed power from the external BEC.

I found the model light on the control and very very forgiving because as soon as it lifted off the ground it felt like a giant trainer and just could not believe how docile and easy manners.

One item that I still have to determine is why it sinks quickly as (not viewable in the Video) it came close to the field's edge and almost became a boat. Perhaps I have too much EXPO on the Elevator...hum..... "Or" it is nose heavy.

Anyway, I used the actual wing antennas that I ordered from HSDJETS for this model but, I used the securing pins that I bought from ACE Hardware as I liked the size instead the hardware pins from HSDJETS.

Please realized that I flew this model without any frontal Cockpit windscreen nor any windows of any kind! Those at the RC Club were very disappointed that this model has limited parts selection and commented very negatively about not being able to obtain the Frontal Battery Hatch from HSDJETS without forcing the customer in purchasing the entire FUSELAGE in order to get the Frontal Battery Hatch!

Okay, here is the video:

Inspired by a French design in Model Magazine with an updated Wing Planform and Airfoil. The Pod and Boom fuselage came out really well, and the modern Clark Y "Strak" looks good in XFLR5.

i think you have heard this word before.
in simple words?
Modulation is the act or process of giving a wave or signal the amplitude or frequency of another wave or signal. In telecommunications, modulation is the process of conveying a message signal, for example a digital bit stream or an analog audio signal, inside another signal that can be physically transmitted.
and, how it works?

i hope you will see things more clearly... or less muddy.
