RaptorNet 0 Posted May 7, 2022 Hi there all I'm hoping someone here might be able to offer me an answer to this query. I bought a boxed MK 2 Jet Hopper recently which didn't come with a remote and I've been hoping to find a replacement substitute. Went to a car boot sale last weekend and picked up an Acoms AP-227 which has a swappable crystal. The only thing is, I don't know the exact frequency the Jet Hopper works on, it says 27mhz, but looking at crystal online, there are more then a couple sharing that frequency range. So I was wondering if anyone might have some advice. This isn't something I have an awful lot of experience in, so i thought better to seek out advice :-) Share this post Link to post Share on other sites
