Put this receiver in a Multiplex Funjet. Works perfectly fine. Voltage monitoring is very useful to determine when it's time to land.

Great little receivers for flying wings, FPV Wings, combat wings etc Small, lightweight and tough... I've used these since they were released and have yet to have one fail on me despite all kind of abuse and the RC link is second to none. Items were quickly dispatched and received.

The delivery arrived in 3 weeks, completely undamaged and in good condition. I am 100% satisfied with the quality of the products, although I have not tested all of them yet, but at first glance they all seem very good. Thank you for the excellent service!
