What is it At US$39 these are possibly not worth repairing, but it’s always interesting to see what’s inside, how it works and there’s the challenge of making it work again. Available from Hobbyking. Most parts are available as spares. The problem – The repair One motor then two wouldn’t […]
Failure At the last indoor flying event I found that one of the motors on my quad was doing its own thing; beeping randomly, starting and stopping when the controller was in safe mode. The ESC is one of 4 HobbyKing SS (super simple) 20 Amp I bought about 2 […]
Selecting a ESC for your RC model Always Over-spec the ESC to be safe, even with the “good” ones. I’d suggest 50% over, and the HK ESCs are OK. For a 40A rated motor, choose a 60A ESC. Always start with a power meter connected and increase the throttle while […]
I think I’m going to have to pull finger and look at building a simple RTL controller for RC model planes. This post is a series of notes just to put it all in one place and provide some food for thought. Comments or questions are welcome. So what is […]
Corona CT8J Module I’m using a Turnigy 9X transmitter with ER9X firmware and a few different transmitter modules including this Corona DSSS 2.4G. I recently had a few control problems with the Corona DSSS system and finally noticed that tapping the module could make or break the RC link. […]
I decided that the ESC-BEC caused a problem in my 2M Elegance glider and had to do something about it. A minor crash due to the BEC getting hot and shutting off. The BEC powers a 8-channel 2.4G receiver, 4 small E-Sky digital servos and a couple of LEDs on […]
It was a nice early evening at the flying field. Not too much wind and a bit of lift early on. I was moving the sticks and it just did its own thing. I was stupid enough to do it twice; just to prove there was a problem; yep, confirmed. […]
A 40MHz control problem recently got me thinking again about lower frequency vs 2.4GHz control. I’m still using 35MHz as are a few others locally, as well as 40MHz and 72MHz. Local Testing I live about 2KM from the flying field so I can listen or test for radio activity […]
