Product overview
The GEPRC GEP-ST35 Frame provides an airframe kit for a 3.5-inch freestyle UAV build. Its 155mm wheelbase and 142mmx118mmx36mm frame combine a 2.0mm top plate with a 4.0mm bottom plate and 4.0mm arm plate. Frame weight is 47.9g with the 3D-printed parts and reinforced arm fitted. Reinforcement thickness is inconsistent: the specification gives 2.5mm, while the descriptive text gives 2mm. Additional listed figures of 180 g and 200 × 200 × 10 mm have no stated configuration.
Integration provisions include flight controller mounting patterns of 26.5mmx26.5mm and 20mmx20mm, plus a 20mmx20mm video transmitter pattern. Motor mounting holes are specified as 9mmx9mm and 12mmx12mm, alongside a broader stated motor hole-spacing range of 8mm-13mm. The GP camera mount accommodates a naked GP8 or Insta 360 Go2. Supplied parts include frame plates, reinforcement plates, assembly hardware, three printed mounts, battery and landing pads, a battery strap, a screwdriver and protective tubes. This is an airframe-only kit for component integration.
