I have flown it .it handles quite snappy due to it being shorter. I love the toothfairy frame. It was a learning curve for the 20x20 stack i had the positive wire rip out twice. Ive since ran smaller guage wire and soldered the living shit out of it

if you are going to go 'big' on the xjb stacks its a good idea to take a bit of 20g wire twisted and loop it through the Vbat pads.. then soldier the shit out of both sides and trim it.. this was you can run 16g wire and 'real' motors with out creating a bottle neck or ripping off pads.. i just finished my custom uni body 5" built wit the f428 stack.. its pretty rad !

Could i possibly check out some pics of the way the wires are routed? Sounds rad. Been on vacation in the philippines. Cheap beer! Good times!
