Wanted a freestyle quad that can take a beating with a top mounted lipo. This is truly an awesome flying machine! The quality of the frame is also phenomenal with fit and finish second to none. I've already crashed it up real good and put some marks on it but it's still alive and going strong. I crashed it face first on the asphalt and the aluminum cage saved the day on the fpv cam. Update Here's a recent video running this on 5S with 5040 4-blade props with some new tweaks to the tune.
