ESP32 Serial Driver for MacOS

It is here, under the Drivers tab:

https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers

There is an installer and uninstaller.

When you install, you will probably get a security warning and have to allow it in System Settings.

Realflight Channel Information

Courtesy of flightengr at Realflight Forums:

Most models follow some standard conventions.

All helis have a Throttle Hold feature on RealFlight Channel 9. You need to release that hold in order to make the heli responsive to the throttle.

Planes generally have:

flaps on RealFlight Channel 6 - Flaps, the landing gear on RealFlight Channel 7 - Smoke, and either SAFE Panic Mode or Thrust Reverse on RealFlight Channel 12. Both planes and helis equipped with SAFE flight modes use RealFlight Channel 8 to change modes.

You don't mention which controller you're using. If you're using the InterLink DX controller, here's where you'll find those functions:

Switch A - RF Channel 7  - Smoke and landing gear
Switch B - RF Channel 8  - Mode
Switch C - RF Channel 5  - Elevator Dual Rate
                          (or Dual Rate for all of Ail/Ele/Rud
                           when only one switch is used by the model)
Switch D - RF Channel 6  - Flaps
Switch H - RF Channel 9  - Throttle Hold (for helis)
Switch F - RF Channel 10 - Aileron Dual Rate
Switch G - RF Channel 11 - Rudder Dual Rate
Button I - RF Channel 12 - SAFE Panic or Thrust Reverse
                          (depends if the model has either of these features)

If you're using your own radio as a controller, you'll have to map your radio's channels to the RealFlight Channels using the Controller Profile.

Eachine E130 Helicopter

 Eachine e130 2.4g 4ch 6-axis gyro altitude hold flybarless rc helicopter rtf Sale - Banggood.com

• Flybarless, no collective pitch.
• The printed manual seems to disagree with some of the online specs.
• Protocol: DSMX DSM2 PPM "S-SUS".
• Battery: 2S 700mAh 20C, JST.
• Hover Switch? "It's for trimming up the helicopter. The controller will not remember trim settings between flights unless you use this button. To trim, first press the hover button for 5 seconds until the controller beeps, and its power light starts flashing. Then launch the helicopter, and be prepared to counter any uncommanded drift with the pitch roll stick. If you notice drifting, repeatedly press a corresponding trim button to negate that lift (those little buttons to the left and below the pitch roll stick). For example (Mode 2 controller), if the heli is drifting left, repeatedly press the right arrow trim button located directly below the right stick until the drift stops. If drifting forward, repeatedly press the back (down) arrow trim buttoned located left of the right stick until the movement stops. Once stable hover is achieved, land the helicopter, press the hover button again until it beeps and the light goes steady. Then turn off the helicopter and controller. The controller should now remember your hover trim settings for successive flights. By the way, there's also a gyro calibration for extreme drifting. Place the helicopter on a flat level surface, then move and hold both sticks to the lower left corner until the helicopters lights blink indicating that it is calibrating. Calibration is completed once the lights go steady. see less
• Rate Switch? "Top left button is the high/low rate button."

Mixing for Axial Rolls

 Read somewhere:

Finally dialed in some aileron to elevator mix, so that there is some down elevator when ailerons (right or left) are moving.

Your results may vary, after some trial flights I have now some 35% aileron differential, and 25% aileron-elevator mix (positive for right aileron movement, negative for left aileron movement), and the Wingnetic now rolls the way it should.

Powered Solder Sucker Notes

 Some good tips from the Amazon page.

• BIT/DESOL3 is the replacement tip. Look at the other answers, they say it has a 2.1mm opening.

• This isn't made to be used like a pencil like the non-heating ones. The button is near the back! The way you hold it is (to explain in words here) by opening your (right) hand and placing it in your palm with the plunger push-down at the same side of your palm as your thumb. Wrap your hands around it. Your thumb is now right on the release button! Hold it like you are stabbing the pc board. Place perpendicular to the board, wait maybe 3 secs, then use thumb to press the button. No shifting, jerking, momentum issues, etc. Just lightly tinned holes/pads after you are done.

• For cleaning, Seller is wrong. Very cleanable. Instructions on pkg, but there is even a better way... Look closely at the housing/base where the plunger rod goes into the black end of the yellow tube. You can see the bigger outer housing you hold has a little partition at the top of the suction tube. The yellow tube is cradled in the outer tube. Use a small flat screwdriver and lever it slightly and it pops out - the whole tube. It comes apart for cleaning. An old toothbrush cleans the plunger well. It seems to all gather at the end of the plunger. It has a light coating of grease, probably silicone paste, so if you remove it by washing you may need to re-apply...

• Properly tin the tip the very first time you heat it up, and treat it like a soldering iron!--ie: keep the tip wet with fresh solder while you work. *Adding* solder to a joint you want to *desolder* is a "secret" well-known by the experts because it keeps the joint fresh and flowing rather than brittle and plasticized so that the solder flows well and the joint is cleaned nicely when you press the vacuum button. Also be sure to hold the iron vertical to get good suction when sucking. And let me repeat: if you say the iron is not hot enough you are WRONG! (in 98% of the cases). What you need to do instead is *add fresh flux-core solder* to the iron tip--get it all up inside the tip even, then place the tip over your through-hole leg to desolder and now the fresh solder will flow the heat right into the joint--press the vacuum sucker button and voila! You've just cleaned that joint perfectly!
