This frame fits the DJI 03 / Walksnail FPV air units.

This 3" version of our world famous Shocker 4" / 5" doesn't need much introduction. Yes it is smaller but please do not call it "cute". It gets angry when people call it cute. We have taken this fantastic example of FPV goodness and performed the following alterations: 

• Reduced arm length to provide the smallest package possible for 3" props while not going so small that prop-to-lipo clearance becomes an issue. This arm reduction may sound trivial but frame inertia has been drastically reduced increasing both agility and crash durability

• The tabs that hold the front camera cage plates to the fuselage top plate have been beefed up to aid in crash durability

• The rear cage plate geometry has been altered to allow for larger electronics to be installed such as some of the upcoming HD VTX options from Shark Byte (aka Divimath) 

• Extra M2 holes have been added to the fuselage top plate and crossbrace to facilitate installation of the new "whoop style" 25.5 x 25.5mm AIO boards 

• If you own a Shocker 4" you CAN convert it to this 3" by changing out the arms and front brace. You have the option of also replacing the rear cage plates and crossbrace but only if you require the features our current design alterations to those parts provide (see above)
