Servo wobble not to be confused with jitter, twitching or humming.

I've been flying for 35 years, I have seen this problem at least on three occasions on different aircraft.

Servo wobble is where the servo appears to go past the center point and then has to come back overshooting the center again going back and forth eventually settles down at center. This would suggest a bad connection. The servo also appears to be moving slower.
This could be due to a bad servo lead extension or the servo wire/connector itself or a bad servo. The bad connection could even go all the way back to the receiver.

First thing to do is to test the servo by plugging it into another source for example if you have an aileron that has wobble, and there are two servos for the ailerons, switch to two wires so the left is right and the right is now left. If the wobble is still on the same servo then you know it's not the receiver connection. It could be a servo extension lead going to the servo or the connection at the servo. Worst case scenario it's a bad servo.

I cut the nose block this morning....Here's how: I printed the plan and side views of the nose block patterns on plain paper, then afixed that to some light weight cardboard (USPS Flat Rate Boxes are perfect). then I glued those patterns to the blank with a very light coat of spray adhesive (M45 was the best, but it's no longer available). Then I cut the side patterns by pulling the blank across the wire....I glued those back on with a light coat of spray, and then cut the top/bottom pattern...pealed everything off, and I have a nose block ready to be finished shaped and sanded. I'll do the same for the canopy.

Here's a link to the nacelles:

I passed on getting out yesterday in the first NorEaster of the year , with gusts over 40 it would have been epic ....
Experience has shown me that the day after the storm hits ,the wrap around winds continue often with blue sky

The wind was predicted to be 13 , but once at the top I was seeing 15 to over 20. Perfect for a true test for my new mini warbird .

She launched easily with just a gentle push from my left hand ,penetrating thru the wind flat straight and level .

Lift on my hill ebbs and flows and with sun bubbles of sink pass thru , so flying the energy of the air is the order of the day.
Just a tickle of up elevator will show you
when there is lift,
The its important to be aware of the wind direction ,ours vectors around so I fly different areas on the hill or out in
front .
Any way -I removed most of the trim I had added on my first test throws and wound up with a flat elevator

Mini warbird is the perfect description as she rewards smooth flying and signals when she is getting too slow or sink by getting mushy. Just like my bigger 60 birds .
It penetrates well (it is pretty sleek ) and carries its energy pretty good -its only 11.5 oz after all

I put in a 30 minute flight and headed back down the hill ,almost on my but at one point when I slipped on the ice base

A Excellent outing with a excellent little plane

Had to make a new servo tray...took about 10 minutes....got the elevator servos mounted and the aileron servos let in to the underside of the wing. Push rod guides are plastic coffee stirrers

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: https://www.google.ca/search?q=radio...client=gws-wiz
more specifically: https://www.we-online.com/web/en/ele...more%20parties.
this in particular explains it well what the letters used by brands: https://oscarliang.com/rc-protocols/
here we find links to most brands: https://www.rcgroups.com/forums/show...o-RC-Protocols
and here he tells us which 1 is better: https://www.liveabout.com/dsm-rc-con...eivers-2862526-but 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
