These are the new V3 SCARAB engine mounts / engine coolers (5 Feb 2014)- now standard issue on the Scarabs - now 3mm thick yet still only 7.2g ! - the bracket clamps down over the boom - works with 12/11mm booms and also 12/10mm or 12/9mm booms - Anodised red/BLACK Aircraft grade aluminium designed / made by us here at MultiCopterPilot.com for the SCARABs.  Makes maximum use of the streamlined aerodynamics of the 12mm boom - both Aluminium booms and CF booms in 12mm. 

Features

• Locks the engine firmly on the 12mm boom - locks the engine in X, Y and Z axis
• Cools the engine stator - soaks heat away from the engine stator and windings
• Easy to alter the tilt of the engine for vectored thrust yaw control
• 7.2g - Light weight
• 4*Engine mounting holes - D19•3mm  
• 3*M3 threaded holes for Claw landing gear and future use
• Anodised to prevent corrosion - black

Includes

1 x engine lock ; 1 x saddle clamp ; 2 M3*12mm bolts  

Requires

The mount must be angled/tilted to vector motor thrust - we recommend 3-5° tilt 

Note : use a 0.5mm spacer when installing prop collets to prevent the prop collet collar touching the engine mount/cooler - bolt the prop down - then pull away the spacer to leave a 0.5mm gap between the prop collet and this engine mount.
