Hi as I am new I dont know where to place this question. There are 2 choice for telemetry (as I know) 900MHz and 2.4 GHz .
What are their difference (usage/setting) pro & con please. I saw they have same price.
I am very new to this UAV things but actually not new to aviation as I am an airline pilot driving A320.
I ve just started to research my project with UAV for aerial photography and mapping.
I really need more knowledge about almost every thing.
