I've been wanting a fastback for forever. I ended up building the pair of spaceone Rip1/Rip2 while waiting on fastback to get on the market.

Every component here was purchased on black friday (woo!!) and/or was given to me as payment for some quad repairs. So my total cost is below what is listed (by 15-25%)

Fastback 5" Stretch X with 5mm thick arms is my configuration. Lifetime warranty. Amazing Design. Super responsive customer service. One of my favorite companies. I've build two micro neatos but this is my first 5" setup from them. I don't think I can break the pod but I know all the carbon is covered for warranty. it is noticeably longer than my other 2 stretch X's (photo on the wall of quads for comparison)

EFAW motors also have lifetime warranty. And so this will probably not stay pretty for long because I have the most incentive to bash the living hell out of it. These motors sound soooo cool, hollow shafts whistle at about 50-70% throttle and it sounds like a supercharger.

Still testing different props, but knowing these motors have torque + efficiency I went ahead and put the highest pitch cyclones I had around the house on it. They are fast at top end but not super responsive on the low end (as expected). I may test 5046 cyclones as well. also GF5152 triblades. These 2500 do spin up noticeably slower than my F80 2200kv motors (as expected) but this build came out lighter than my build with those, by about 100gm, so this setup is still completely responsive. I think AUW with the lighting is around 550, without is closer to 520gm. heavy for a quad with no gopro but I got the 5mm arms because I plan on smashing into things.
