The RC Crazed Slim Phast is a purpose built racing frame and this new 4" model is no different.  It is light, strong, and feature packed. We designed the 4" variant around a 20x20mm stack to make it much smaller in the center section.  This gives you a very proportinal looking model with 1407 motors and 4" props. This frame is also designed around the RunCam Micro Swift FPV camera.  Full-size and mini cameras will work but you won't have the same degree of protection for your FPV camera.  This thing is very rigid and sports 4mm thick arms that are 10mm wide which are a good fit for some small 20A ESCs.  The arms are wide enough so that they don't turn in to rubber bands from the torque twisting produced by powerful motors and thick enough to crash and crash and keep on flying.  The main plate is 3mm thick and the top plate is 2mm thick. There is a slight stretch to the frame and the MTM comes in at 180mm.  We went through several prototype revisions to find the right balance of weight, strength and flight characteristics just like we did with our 5" model.  The Slim Phast 4 is designed around a 20x20mm stack and has M3 holes for the stack mount.  Try out a set of our M3 to M2 adapters if you want to adapt the M2 to fit snugly in the M3 holes.

Our local Cleveland Quad Squad pilots really put this frame to the test and we kept refining it, a little longer here, a little wider there, a little thinner here and the result is pretty awesome!  

We have taken this frame and built it with top notch components to make our Bind and Fly model.  We use an F4 Flight Controller coupled with Dshot 600 ESCs to give you a super high performance build!  We used brother hobby 1407 motors for some serious thrust and speed as well as a switchable 25mW/200mW VTX, and a RunCam Micro camera to give you clear FPV video.  Chose your receiver protocol and we will throw on either an XM+ reciever for FRSKY or a Lemon Rx diversity satellite receiver for Spektrum.  These models are test flown and tuned to ensure you receive a well working, great flying model that is ready to rock out of the box!
