Blade 230s tail boom slotting jig

thingiverse

This is a blade 230s tail boom slotting jig. put one peace of the jig on each end of the tail boom after boom is cut to length. then snap the jig down flat to the work bench. this will align the holes for the slots. K&S #9807 aluminium tubes are used for the new boom. cost is about $4 for two tubes shipped. drill the 3/32 hole through both sides of the tube. Drill the larger 1/8 hole through one side only. then use a dremel tool to cut the hole to the end of the boom making the 3 slots. the new boom can make a 40mm stretched boom. a boom cut to the same size as the 230s part is 1 gram lighter. the 40mm cut off end can be made into a reamer for a perfect fitting jig. just cut teeth into one end with a file. then score the outside of the tube with a hobby knife. chuck it in a drill and ream the jig.
