My guess is it's a 2.4Ghz narrow beam jammer. It would likely have little effect on say a 400Mhz receiver. Not to mention it is reliant on a predicable failsafe

My guess is it's a 2.4Ghz narrow beam jammer. It would likely have little effect on say a 400Mhz receiver. Not to mention it is reliant on a predicable failsafe. What if the failsafe is 100% throttle. It would be pretty easy to make this device useless.
