title_body: Effect of Deadcat frame on performance? I've seen a lot of new frames with a Deadcat style because it keeps the props out of view for cinematic videos and such. Does the Deadcat shape of frame have any effects on flight performance?

    I was more interested in how the dynamics of a dead cat might affect efficiency.  But based on what some of the long-range guys have found, it doesn't appear to be an issue.

Once they started setting up as a custom in BF and used the program that Project Blue Falcon explains, the instability went away.
