Hey guys, I'm new to the forum, but recently got my PHANTOM in July, I flew it about ~10 times so far since. I been using the Graupner 8 x 5 props for about 2 months, but feel as if when i ascend and descend it's wobbly. For you guys with experience, how would you rate them? I read that they are good, but just did a quick search and read otherwise - what other props would you recommend? or just go back to stock?
