Product Details<\/h2>\n

Most long-range pilots default to 7-inch or jump straight to 10-inch. The MARK4 V2 8 inch FPV carbon fiber frame<\/strong> sits in a sweet spot that a lot of people overlook \u2014 more prop efficiency and payload room than 7-inch, but without the weight and bulk penalty of 10-inch. If your typical flight is 3\u20138km out and you’re carrying a camera plus GPS, 8-inch props give you the best thrust-per-watt in the MARK4 lineup.<\/p>\n

6mm Arms on the MARK4 V2 8 Inch FPV Carbon Fiber Frame<\/h3>\n

The 368mm wheelbase isn’t just a stretched 7-inch. The arm length and stack spacing were designed around 8-inch prop clearance from the start. 6mm arms on an 8-inch frame might raise eyebrows when you see the 10-inch version gets 7mm. Here’s why 6mm is the right call: 8-inch props generate less torque than 10-inch, so the arm doesn’t need the extra millimeter to stay rigid. Going 7mm here would add roughly 25g for no measurable improvement in flight performance \u2014 that’s weight you could spend on a bigger battery instead. The 6mm 3K T300 arms are cut from our own carbon fiber sheet in-house, so the material consistency is the same on every batch.<\/p>\n

2.5mm Camera Side Plates on the MARK4 V2 8 Inch Frame<\/h3>\n

The plate stack mirrors the proven 7-inch layout: 3.0mm bottom and middle plates handle the structural loads, 2.0mm top plate saves weight where you don’t need maximum stiffness, and the 2.5mm camera side plates keep your camera mount locked down. On 8-inch builds with 2806 or 2807 motors, even a tiny amount of camera mount flex shows up as micro-jello in your footage. Those 2.5mm side plates are the difference between clean clips and footage you have to stabilize in post.<\/p>\n

210g total frame weight. Arm soft mounts come included to eat motor vibration before it reaches your FC. Battery pads, straps, aluminum standoffs, and full stainless steel hardware are in the box. Motor holes fit 16\u00d716mm and 19\u00d719mm, FC mounting works with 20\u00d720mm and 30.5\u00d730.5mm. You can go from unboxing to a flight-ready build in one session.<\/p>\n
