so the other day i went to fly my 4s raptor but found all my 4s packs had taken a dive and instead of buying more 4s packs i went for a motor upgrade.. this time future proofing my ability level with the Tmotor f60pro v2's in 1750kv.. also while this build is a bit on an inbetween upgrade of the raptor 210 SX with mk3 arms in true X in the rear.. the arm ugrade has a touch more meat around the motor mount an more importanly it incudes the 5.1mm cut out in at the center of the quad for the alloy mid plate ( the first version got lost by australia post :( ) which hopfully will be cut in the next few days.. the hybird is not the usual 5" SX front 6" X rear.. ive gone in for the less extreme 5" all round with the true X rear arms.. shes also sporting the lastest bleeding edge BF test code, the real time bidirection rpm telemetry driving narrow notch filters on each motor instead of gyro filtering, a narrow dynamic notch to clean up and left overs and one throttle based dynamic dterm LPF filter.. also shes using the new Dcut code which only brings in a high D value at the onset of propwash or in a high rate flip or roll where overshoot needs t be managed.. basically very little completely adaptive filtering and D... 4.0 is going to knock some socks off
