This is the BMS Racing JS-4 Tigershark. Our highest stiffness, most durable machine to date (assuming no arm braces), featuring sensational cornering feel, intuitive camera placement, & class leading serviceability.
Other notable features include:
-46mm spacing between the standoffs lengthwise - Plenty of room to mount a wide range of esc/FC stack combinations
-Symmetrical Stack bolt location front-back - bottom plate, mid plate & brace plate are bi-directional
- Three bolt motor mounts - Reduces chance of motor base bending & likelihood of arm-neck twist
-Custom arm "air-interlock" system - All the stiffness benefits of frames built under tension with most of the durability benefits of our JS-3 platform for longevity.
-Optional TPU "16mm Battery Strap Cushion" - Centres 16mm battery straps in its thru-hole and better distributes load across the battery strap. This allows for tighter grip of the battery and more longevity out of lightweight race grade battery straps.
-190mm motor-motor spacing - Reduced rotational momentum which improves handling across the entire spectrum of flight.
-Arm bolts separated from stack bolts - Can change arms without having to re-tension nuts on the stack bolts.
- AUW including all hardware 59g.
