Impact Test Results
Minor cosmetic scuffing.
Small cosmetic chip around motor mounting area.
Small inner stress-line fracture, still fully flyable.
Impacts 1–2 minor damage; impact 3 major structural damage, but still flyable.
Catastrophic failure. Unflyable on impact 4.
Strengths
+ Exceptional impact durability
+ Surprisingly stiff for an FDM printed frame
+ Designed specifically around larger Li-ion FPV builds
+ Replaceable/printable at very low material cost
+ Thick structural sections tolerate severe impacts without immediately fracturing
Weaknesses
− Significantly heavier than carbon alternatives
− PolyMax Tough PC is considerably more difficult to print than common filaments
− An enclosed printer and hardened steel nozzle are recommended/required for the intended printing setup
LithiumIonFPV designed the Riptide. The same test procedure was used for every frame, but readers should consider the possibility of unintentional tester bias.
