Well, I have no doubt about passing the exam. It's the fees, the unnecessary questions that will never impact us hobbyist that are just wanting some cool arial photos, while hiking or at the beach with no civilians around. So, since this 250+ grams thing is a magic number that TC feels makes a drone that much safer than one 302 grams (huh?), I'm going to see if I can reduce my Spark to 249 grams. I just ordered a 49 gram carbon fiber frame and will Frankenstein Sparkie into it and see what else I can trim off to make it 249 grams. I'll keep you posted!
