The Shocker HD Freestyle TANK from Catalyst Machineworks


This is a highly altered version of our Shocker HD Ultralight Frame. The basic structural design elements of this 'tank version' are very close to the ultralight. If you are not familiar with the original Shocker please watch our design review video. So what changed with this new freestyle tank? We have updated all of the parts to add a significant amount of material and also altered geometries as required to result in an extremely rugged frame. The intended purpose of this monster is aggressive freestyle flying while carrying heavy GoPro cameras (or similar). You will be able to beat your Shocker like a red headed stepchild with reckless abandon. The top deck has been extended by a large distance (115mm) to allow for very large capacity lipos. Why would you want to run such a big lipo? Todays motors are becoming ever more powerful and larger stators are now commonplace. You need a BIG lipo to supply all that power. Provisions are made on this frame to fit the DJI Air Unit or Caddx Vista HD FPV systems. Full sized flight controllers and ESC's will fit in this tank and there is plenty of space for even the largest AMP hungry AIO speed controllers. The arm pads are sized properly to fit traditional freestyle motors. The same 3D printed accessories that fit the Ultralight Shocker also fit this version! Sure all that functionality and durability is important but what about looks? Are you kidding me?! Look at this thing! It looks AMAZING. Now you can be the coolest kid at the FPV pool party.
