That was in response to me commenting that I popped both inner ball cups on a flat landing with the angled cups on the inside. I intend to try them again with the cups mounted properly, but have been unable to so far due to frying my esc (plugged it in backwards, doh!).

I will have a practice day this Saturday, so I will try the other set on my b44 this week end & report back. Although, others who have mounted them correctly have stated they work well.
