Gopro Session Mount for Impulse RC Alien 5.
Mount is designed to be fastened with the bolts that hold the topplate down.
I use longer M3x12 bolt for use with the TPU mount and some M3 washers for better mounting.
The Gopro is mounted as far back as possible but still allows for a 1300MAH Lipo to be mounted. (for better overal center of gravity)
I use this mount on my own Impulse RC Aliens without any problems.
