I meant pointing it straight up versus pointing it straight down. If you have watched the build video for tricopter v3, when David sets up his antennas for the optima 9 receiver, he points one up from the main body of the tricopter and then points one straight down by attaching it to the boom of his tricopter. up or down (vertical not horizontal).
Wondering which way is better for when i eventually get to flying higher up in the air. I have the hitec system, optima 7, so only one antenna. thinking about getting the 9 so i have both.
