You seem to be "on fire"! I hope your enthusiasm lasts. Seriously! Producing vids, prolific flying enthusiasm in conditions most wont even consider a trip to the field....obviously a performer of more than one art.
I bet you could draw (literally) from the knowledge you already have, (with a pencil) a design of your own, with the aerodynamics you read about avidly, and produce something that would propel you further than the purchased, processed offerings you currently fly. Study a few of your faves, combine the numbers. Your artsy spin on looks.
I have been reading your posts quietly since you started here. And it is great to see you having so much fun!
You won't reinvent the wheel, but you have flown enough birds, to know what you are looking for and get to the next level in short order. Drag a blue rubber Nobler anywhere for competition and be sold short or skill in scores. Build a bird of your own with a decnt finish that performs well...and you will climb.
A bit presumptuous on my part but, I am a musician, an artist and an engineer or sorts. Try it out Sugg!
