    I posted an earlier version of this modification a year ago in the general discussion forum. Someone revived the old thread and suggested I post it in this forum along with the newer mod photos. I have uploaded the part to thingiverse.

    The modification allows longer batteries to fit into the P1 and shifts the weight farther to the back to help balance the weight of a camera and gimbal. It requires cutting out the back end where the LED is mounted and attaching a 3d printed part with screws. The front battery compartment opening has been opened up slightly as well to allow taller batteries such as the Multistar 4000mAh to fit. With this battery I can get an easy 20 minute flight time, more if I pushed it. The battery was at 11.2 v after landing and came up to 11.3 within a minute. These batteries have a lot of sag so I had my first warning set at 10.7v.

    Did another flight with the gimbal and GoPro attached. Easily got 15 minutes landing at 11.2v and bounced back to 11.3 again in just a minute, so I could have gone longer. This was at 40 degrees with a little wind. Also had some toilet bowl effect since I forgot to recalibrate the compass after adding the gimbal and camera.
    Total weight is 1170g with this setup, 9443 props, taller landing gear, Feiyu-tech 2-axis gimbal and GoPro 3+.
