Product overview
The iFlight BOB57 Frame Kit is designed for long-range cinematic and freestyle flights, developed in collaboration with pilot and videographer Ellis van Jason. Its H-shaped frame has a robust middle section that reduces propellers in view, while the hybrid motor design supports both bi-blade and tri-blade 6-inch propellers. A solid antenna mount reduces oscillations when using long antennas. The Gladiator shell provides protection from dust and water droplets, and the XT-60 mounts at the front.
The frame has a 278mm wheelbase, measures L165*W225*H34 mm and weighs 305g. Construction uses 6mm arms, a 1.5mm bottom plate, a 2mm top plate and a 2.5mm upper plate. Maximum flight stack and VTX heights are each 22mm. The kit supports the DJI O4 Air Unit Pro. Manufacturing tolerances may be ±2mm overall, ±0.2mm for thickness and ±0.1mm for hole size.
Supplied equipment includes the BOB57 frame kit, BOB57 TPU parts, four motor wire shield tubes, a battery anti-slip pad, two battery straps and a screw bag. The O4 version also includes one 220mm MIPI video cable for the DJI O4 Air Unit Pro. The included dual-antenna VTX TPU requires two IPEX to SMA adapter cables and two antennas. IPEX to SMA adapter cables and the Anti Spark Filter are not included. Single-antenna installation requires the separately purchased O3 Single DJI Antenna TPU.
