Yes - the "01" series is a great series to use on any FBL system. And 550 size blades are a much better load with the proper gearing for a 6S power system.
The 600mm to 620mm blades are better suited to the 8S and 10S power systems respectively.
I did not make the frames but I did make all the aluminium parts. Was going to run 10s2pA123 so thats alot of weight just in batteries. Honestly I forget why I stopped on the thing. Time and money time and money
The good ole times are now ,Hawk, Raven, Raven NX, Logo 10
funny how you never seem to have both " time or money"
The reason I am thinking of using the raven was to cut down on weight 1 plan was (a)to remove the fan shroud (b)design a lower carbon frame relocate the motor to the front (as seen in your pics "Fboss" mount battery up front and radio stuff in the rear. (c) make all this work with current parts in production
