1806 2400KV


It come with 2 model, white (CCW) and black (CW) cap. The different is only the motor cap turn clock wise or counter clock wise. I bought it at AliExpress for ~$6.50 each. There is no selection of KV for same brand, only 2400KV. Unlike the 2212 where there are many different KV you can choose. I do see same motor specification but with different color and brand.

Description:
  • KV : 2400
  • Stator diameter : Ξ¦18mm x 6 mm
  • Motor Weight : 16g without cable
  • Recommended battery : 2-3S
  • Maximum current : 6.5A (based on the table below, it cango 11.3A max)
  • Maximum power : 70W
  • Propeller shaft size : Ξ¦5mm
  • Propeller size : 4-6 inches

Below data is not by me, one of the shop did the test.



Another experiment data from other shop, different motor brand with lower KV but physically look the same

Building RC Plane Under 250 grams (Part 1)

Image
Building RC plane is not easy, choosing brushless motor is already very confusing. There are so many parameter need to consider (motor size, motor weight, propeller size, battery size, etc) 😡   In the end, I asked ChatGPT πŸ˜‚, I summaries ChatGPT answer on the table below. In conclusion, to be able to fly without license, I need to built something under 250 grams. Based on the table, 2212 that I bought is suitable for 300 grams and above. I bought the wrong motor, waste money 😑, should asked ChatGPT earlier, part of learning πŸ˜‘. I took measurement on components that I have in hand using kitchen scale 2212 motor = 61.21 grams 30A ESC = 25.59 grams Receiver = 30.20 grams 3x servo = 31.95 grams 2x 18650 battery = 100++ grams Total 248.95 grams excluding the airframe 😭. I ask my good friend ChatGPT to recommend RC plane design with target weight of 200 grams (keep 50 grams for margin) and the answer: Wingspan: 60-80 cm (100 grams) Motor 1806 or 2204 (15-25 grams) ESC: 10A - 20A ...

Arduino Nano clone (fake FT232RL)

Image
Couple weeks ago, out of curiosity, I just bought Arduino Nano from Aliexpress. I saw it was on sale for S$1.39 (tax included). Arduino Nano with USB=C cable for S$1.39 is very-very cheap 😊, other shop sell at around S$3+ (at this time I did not know it was clone). After about 2 weeks of waiting, it is finally arrived. This thing is tiny, measured around 1.7 x 4.3 cm. Looking at the soldering are good and clean, I'm pretty happy with the product. 😊 I download the IDE 2.3.2 software from official Arduino website ( https://www.arduino.cc/en/software ). This is the time I realize it is a clone because the original Arduino Nano price at US$21.17 🀯 from the official website. With the price different, there is no way I bough the original πŸ˜‚. I'm trying to share my first experience experimenting with Arduino Nano because it is not a smooth sail, although with the help of google search, I manage to overcome itπŸ˜‰. First of all , you need internet connection when open IDE software for...

A2212/5T 2450KV

Image
I wanted to post screen capture of the motor that I bought, just for personal note. Otherwise I most likely forgot the specification in a week time or less. There is no particular reason why I choose this motor, it just happen to see a bundle deal "Brushless motor + ESC" for S$10 πŸ˜‚. Many of specification mention are confusing, I have no idea what it mean πŸ˜›. After some googling: A2212/5T: 22 is the stator diameter in mm, 12 is stator height in mm. 5T is the number of turn per pole. Its the inner core size, not the outer motor size KV: RPM per Volt, 2450KV = 2450 RPM when supply with 1 Volt Max Current 12A/60S: mean can operate at 12A for maximum 60 seconds before it melt, maybe 😱 Load Current 25.2A: The maximum current the motor winding are designed to draw under specific conditions Max current = 12A/60S and load current = 25.2A, does it mean at max load the motor will burn? Why the load current is greater than max current? How do I choose battery to run this motor? Do I ne...
