Ref weight, it's interesting to note that the Hyperion with the prop adapter weighs exactly the same as the YS shown in the photo.......530 grams.
Remember to also factor in the header, retention bolts, tuned pipe, silicone coupler, soft mount, fuel tubing, stinger, your patented 12" of high tensile bail wire to tie aforementioned together... The eelctric will also have a few adders but I think it will come out ahead in the long run
