At Silhavy Aerosports we use modern high quality CNC machines to cut foam and ply parts.  We can cut parts from 1/2A planes up to 50% scale airplanes with no problem.  We can cut from your .dat or .dxf file or we can draw the part in CAD for you.  NO SETUP FEES!  Give us a call or email and we can quickly get that new part cut for you ASAP.
