I just ordered the Argtek mod for my P3S and am very anxious to get it installed. I have not had very many flights with my drone yet, but I am the type of guy that looks at what is available and what people recommend for stuff like this and then jump on it. I haven't (and won't) run out and buy every single mod, accessory, and option out there, but something like this seemed like a good investment. I ordered it directly from the Blue Proton site. I never buy stuff from eBay because I do not trust sellers there. I will share my experiences once I get it going. Should have it in a few days.
