GIANT R/C Scratch Build Based on C-133


Junior Member
This video is a year in the making - local Marymoor R/C Club members Bryan, Hailin, and Ian came up with the idea of making an extremely light for its size C-133 based aircraft after visiting Oshkosh in 2019. Soon thereafter, their newspaper build plans turned into a full on massive project, and almost a year to the day after starting it, she took to the skies for the first time.

Congratulations to all of you with an awesome build and incredible flying airplane. Build 'em light!

Stay tuned for a 45ish minute podcast style build log video from the builders.
