EPP Foam Planes
Just put FF-50 build rcfoamfighters in the search window then pick videos and it should come up
jkreska, Watch the FF-Viper-50 Build Video. The FF-Viper-70 is basically built the same exact way, just bigger. There are 3 EDF rings, two are glued together to be stronger and go around the EDF end. The third ring is used to support the thrust tube.
