I am doing this as I post. Anybody take the Phantom 3Pro/Adv landing leg antennas and put them on the Phantom 2? I was curious if the panel P3 bird antenna is directional to which side you use, flat or insert side(side with grooves. Thanks!! Any easy way to get that black glue crap off to remove the antenna connection? Crap! broke the connection on the board! Lucky I had a spare.
