My next project is an SDS Yak Pro from VVRC, DLE 20, Macs 2986 Header and an ES Composites tuned pipe. Excessive? You bet! I like spirited aerobatics but am not into 3D flying (specifically hovering) but I do want it to do as much crazy crap as I can think up. I'm hoping this combo will turn a Vess 18x6 in the mid to upper 8K range. 15lb+ of thrust should git-r-dun!
