I'm trying to figure out why a Skybolt uses a 1286 bungee ring (8.75" ID) vs the Starduster Too 1280 (8" ID). Truss taller? Gear thicker ? Can anyone measure a stock Skybolt from the top of the gear truss to the bottom of the gear where the bungees wrap around? I've included a photo of how I measured my Starduster Too truss setup for example. ImageUploadedByBiplane Forum1414004914.451186.jpg
