1. How many batteries can be charged simultaneously in Normal mode and Quick mode?
In Normal mode, the DJI Battery Station can charge up to eight TB50 batteries simultaneously. If there is a significant difference of voltage between two vertically aligned batteries (e.g., in slots A1 and B1; please refer to the TB50 Battery Station User Guide for slot IDs), the Battery Station will charge the lower one first, and then charge both together when they are equally charged.
In Quick mode, the Station can simultaneously charge up to two groups (e.g., in slots A1 and A2, as well as D1 and D2). It will charge the four TB50 batteries to 90% first, then 100% for any batteries that are still inserted.

2. In addition to TB50 batteries, what else can be charged with the Battery Station?
Apart from eight TB50 battery ports, the DJI Battery Station is also equipped with two 20-26V/3A DC OUT Remote Controller Ports and two 5V/2A USB Ports, which can charge Cendence, Inspire, and Phantom series remote controllers, CrystalSky, Cendence Battery Charging Hub, and other mobile devices.

3. What is Silent mode?
In Silent mode, the Battery Station will restrict the charging current, lower the speed of the cooling fan, and turn off the beeper to reduce operating noise. This mode is recommended in quiet environments with abundant time for charging. Silent mode can be enabled in the menu under Normal mode.

4. Can Silent mode be enabled both in Normal and Quick mode?
No. Silent mode...Continue Reading

I wasn't paying attention - I guess as of December 12th, we need to register again if we fly anything over .55 pounds. If I come back to US then will have to just fly under 249 grams.

Started putting projects on This is not to be confused with The hackaday domanes are a confusing mess of illegible grey on black text, but the few readers might find it more useful. It feels like rcgroups has lost attention to the hackaday, eevblog, properties as the RC world has expanded from toys to industrial robots which control cameras, clean floors, deliver food, drive taxis, & train athletes. An RC vehicle is just as often found delivering food now as it was doing flat spins, 10 years ago.

Steering the lunchbox continues to be a brutal occupation. The stiction algorithm as implemented did nothing. It started becoming obvious that control feedback behaves like an equation. No matter how convoluted the feedback algorithm is, the result converges on the same answer in the long term, like an equation which always outputs a sine wave despite having 1 added & subtracted to it many times. This is why control theorists write their feedback algorithms in equation form. It makes it easier to see what changes reduce to 0.

The stiction problem is specifically caused by the servo saver absorbing much of the motion & less because of the linkages. The servo saver absorbs much motion in left turns but virtually no motion in right turns. Maybe the integral has to be kicked based on swings in the PWM output instead of the heading error.

I recently purchased and set up an FrSky X10S, and while I've had very little trouble getting it going, there are a number of questions that have gone unanswered, and documentation and materials for the radio are scattered in many different locations. To prevent me from having to look up all of this every time I need to find something I will compile here the things I have found useful as well as give a place for others to ask technical questions regarding the setup and use of OpenTX on the radio. As I experiment and find out more information about the setup and maintenance of the radio I will post here and I would welcome the experiences of others as well. My application is primarily mini-quad use, so my resources will be primarily focused there, but I welcome input from other types of pilots and areas of the hobby as well.

Helpful Resources:

I will make a few requests of posters here:

1. Keep to the topic, and keep the questions and answers of a technical nature and free of drama and personal attacks or insults. I will delete posts that violate this.
2. Don't be afraid to ask questions! And conversely don't belittle people for asking questions. If you don't like the way someone asked a question, or you think they could have found the answer by searching, just don't reply and move on.

so i bet u like quadcoptes so u probably know what brushless motor is i bought racerstar BR0703 brushless outrunner motors and they are tiny only 10 mm wide 1mm shaft and they are horrible i was mounting it and the wire simply fell off at that point i was ready to flip a table so if u wanna see me repair them just follow me into this repairing nightmare i cannot get a good pic on the stator how small it is

1. tools + soldering station+1mm drill bit
2. materials bamboo stick 14cm long 4.2mm wide or close to those sizes, 7mm long coarse thread(wood screw thread) screw 1.7mm wide, fine tooth screw 1.3mm wide any length will work
1. unscrew the mounting screws
2. cut or unsold er the wires
3. remove the propeller
4. remove the retainer
5. remove the rotor of the stator
6. remove the old coils
7. remove the mount
8. making the jig
9. winding the stator
10. gluing the coils
11. brake

Well I've finally come to the realization that I can't get any decent amount of aeromodeling done until I get that mess of a man cave cleaned up and organized. I'm a slob, I admit it, and I hereby resolve to correct this character flaw. I'm getting motivated in one way by using creative visualization. I'm seeing the upstairs loft all clean and with plenty of rack and shelf space to put all those parts of airplanes and gliders that I am having trouble letting go of.

"Hey, don't toss that wing out! I can use that someday!"

Uh huh. Yeah, right, if I haven't used it by now, what makes me think I ever will? I will instead build a nice work table, and get my hot wire tools up and running. I'll have wings the size I want with the airfoils I want. Throwing out these Chinese made wings and stuff will actually free me up to finally having a flying apparatus I can be proud of. Making something that flies well with the old parts is possible, I know, but much more time consuming than starting from scratch will be, I believe.

I wonder if modern tools like laser cutters, 3D printers, and the like are something I should strive for. I get the impression that the guys with good computer skills probably profit from the stuff, but it does seem like there's a lot of pretty pictures being created and not a lot of flying machines being made, and a lot of keyboard time invested. I think I'll stick to the tried and true old school methods, and maybe just get the computer geeks to do that stuff for me. We'll see how it goes.

Sure is a lot more fun writing this than it will be cleaning up the loft, I guess that's why I'm so long-winded.

QCY Q29 Bluetooth Double Headset Gearbest Coupon 54% Off

Apple’s AirPods have made untethered Bluetooth earbuds mainstream, but the design itself — that is, two untethered wireless ear pieces — has been around for years. Go back far enough, and you’ll find early models like the Sennheiser MX W1, a pair of big, clunky but functional earbuds that provided stereo audio without a wire tethering them together. As technology improves and prices substantially drop (the MX W1 retailed for $600 new), we’ve seen earbuds of this sort with increased frequency, and joining them are the QCY Q29 pair.

Much like AirPods and Samsung Gear IconX, the QCY Q29 earbuds are both wireless, but not shackled to each other via a physical wire — they’re two independent earpieces that can be used together (stereo) or separately (mono), depending on your needs. The earbuds retail for between $73 and $100, depending on where you get them, making the QCY decidedly attractive from a budget-centric point of view.

Now in Gearbest You can get it for just 60$ > 24$.

As he maneuvered his unarmed B-17 bomber over the island of Oahu, U.S. Army Lt. Robert Thacker was puzzled.

It should have been a peaceful Sunday morning in Hawaii.

I've decided to use this as my UHF setup. Grabbed an EzUHF module from RMRC and used the laser cutter to make a hole in the poor thing. I've been learning the laser the last few days, and this is my first cut on anything that's not scrap wood. It's very clean with the module installed. Tolerances are just about where they need to be, and the module sits square with some adjustment (although, slightly to the right). It's purposely placed a little high to allow for a slight bit more clearance for the main board and wiring. I'm still planning it all out, but I figured a little extra room would be welcome. I've tacked it in with a slight bit of RTV, but the tabs hold well. More for peace of mind than anything. Notice the small dots in the top right from where I was aligning the laser... managed to peck through the tape I was using as a reference. Luckily they're covered by the module. For a first cut on the laser I'm pretty happy, and look forward to improving my techniques.

I'll be using an ATMEGA2560 with OpenTX for the radio. I'm also going to install the small Spektrum RF board and switch between them, so I can use the 2.4 antenna I've already installed. The ATMEGA board should be here in a few days, and from there we should be able to move pretty quickly.
