Strange battery performance

Conversion of sailplane to electric powered folding prop

Today I was testing a new power setup for an old sailplane. The results were strange and disturbing. The sailplane is one that I used to fly with my boys when they were entering their teenage years. And I'm thinking that even back then it was old - acquired second hand. We would either launch …

A buddy box setup is clearly the best way to train a new RC pilot. If you simply stick to one brand of transmitters for everyone involved, that's not too much of a problem. But most flying clubs have quite a variety of systems being used - most of which are not compatible with each …

Your control signal from the transmitter to the receiver is one side of the conversation. The other is the telemetry signal coming back from the receiver to the …

Radiomaster TX16s Custom Displays

Your Radiomaster TX16s has the capability to customize all kinds of things, including the display screen.  It’s quite likely that you have already done some of that, but most likely, that has been haphazard, unplanned, inconsistent and unaware of some very helpful options.  In the document below and the associated YouTube video, we would like …

Please note

Working on and flying radio controlled aircraft can be dangerous, even lethal. Exercise great care, as you are the one responsible for what happens to you or others. Should you try to do anything that we have discussed or demonstrated here or on our YouTube channel, you need to personally evaluate the safety requirements and put into place any safety measures that may be required.

We have put in a lot of work to provide you with all of the information in this website and on our YouTube channel. Anything you would be willing to do to help us out financially would be greatly appreciated, even the value of a cup of coffee! Clicking on the image above is a simple way to do that.

Thank you so very much!
