Flight Log - 2019-08-04 - Matthew Bond's Semroc Heli-Roctor

Helicopter recovery model that releases the blades after boost by using the motor ejection charge to drop the fin can off the back attached to a Kevlar harness, eliminating the need for a burn string.  Blade shape no is accomplished by slicing the balsa blades diagonally lengthwise (partially, not a complete cut-through) then bending the balsa with the aid of pre-cut jigs and glueing the cuts to set the final shape.

Second helicopter duration flight of the day using the same model with pretty much the exact same result.  Nice straight boost off the rod, not real high.  Good blasé deploy and spin-up.  No lift, 18 sec duration, grass landing, no damage.
