Sniper 7

How about a 7" True X frame that weighs less than many 5" frames? This is one of the lightest 7" frames  available with all the features of the succesful Sniper range including stiff boomerang arms and the Tri mount top plate system.
 
At just 76g the Sniper accepts 16x16mm M3 motors only. Because of it's super light weight it can be built with 5mm arms for 24XX or 25XX motors instead of the usual 6mm or 7mm and 28XX normally used for 7". 
 
Every feature of the frame is geared towards maximum strength and minimum weight. With 2mm chamfered main plates and 8.5mm x 5mm chamfered arms, stainless steel hardware and 7075 25mm standoffs..
 
The top plate features the same Atto Tri mount as the Neutrino frame allowing race fins and HD mounts to be easily swapped using 3 bolts without disturbing your frame. The 6" Sniper also shares the same arms as the 5" Neutrino frame meaning you can keep fewer spares for your Atto fleet. 
 
The mid plate features installed M3 Steel press fit nuts to lock the arms in place plus options for 20mm and 30.5mm hardware. We expect this to be run on lightweight 20mm setups so access is provided to the stack bolts for this size through the bottom plate with enough space to remove your stack bolts entirely. 
 
For hardware the choice is stanless steel flanged Torx bolts. Torx bolts never round off and the flange spreads the load over a greater area of carbon. It's the smart option. Standoffs are 7075 aluminium in matte black. Though they are slightly heavier than the usual 6061 versions, the trade off in strength is well worth it. (You'll need a T10 Torx driver for this hardware)
