Hi, I've been trying to buy this downlink system from ImmersionRC http://www.quadrocopter.com/Immersion-RC-58GHz-Uno-AV-Receiver_p_727.html http://www.quadrocopter.com/Immersion-RC-58GHz-Uno-AV-Receiver_p_727.html for about a month but it remains out of stock, and apparently its been out of stock for several months before that. The other popular one here on seems to be the Iftron stuff at nearly 10X the price!!! I need a solution soon, and I don't mind paying more if the Iftron stuff is going to give me better results, but is that the case? I've seen the ImmersionRC stuff in use and it seemed pretty effective, so just wondering what Im buying at 10x the price for the Iftron stuff. thanks,
I have been using Immersion RC 5.8GHz 600mw on my birds without an issue. I have never gone beyond 600-700 meters for testing; I've always had good signal with stock antenna within this range; not even using clover leaf antenna. The good thing about this vtx is the size. No fan. Works good for me.
