I fly Orange Rx mostly, and love them, but I ordered a few Lemons and satellites.
Put a lemon in my Griffwerks MX2, and flew my third flight with it.
My Taranis with the Orange module, needs the antenna removed to fit in the case, so I forgot to attach it.
Flight was un-eventful and was in about a 4 acre area with no antenna on the TX.
I would never try this on purpose, but the lemons seem just as good as the orange rx ones.
