MAMR 5" StretchX Racing Frame

MAMR 5" StretchX Racing Frame

MAMR 5" StretchX Racing Frame

This is our second frame and was designed around some of the latest hardware offerings in the industry.  Just like our first frame, it took several months to design in collaboration with designer Byron Ortiz to get just right.  After much testing with sponsored team pilots we have come up with a lightweight, strong, and agile 5" racing frame.  A few design features include: replaceable arms, sandwich method of assembly which gives the frame more structural strength, carbon fiber top-plate or optional TPU canopy (available soon), battery strap slot in between middle and bottom plate, 30.5mm x 30.5mm and 20mm x 20mm FC mounting holes. To help reduce weight and for durability, we chose to use Titanium M3 button head bolts.
