Eagle Tree Systems specializes in the design and manufacture of data recording and wireless telemetry products for the RC hobby industry.
Here is what they have to say about themselves on their company website:
Our mission is simple but somewhat unusual for Radio Control: manufacture and sell high quality, feature-rich products at a reasonable price, with the belief that people will buy them in large enough volume to let us keep the prices low. Thanks for your help in proving that this business model is valid!
Over the years, your feedback and support have enabled us to launch a variety of data acquisition products for the Radio Controlled model industry, with many more on the way. Our present data recording and wireless telemetry products are the result of much research, testing and honing, and are assembled with the latest cutting edge SMT components for reduced size and weight, and increased reliability.
