RE: RJL head
GCB and lildiesel,
Noted and thanks! I'm one who didn't enjoy it, but then I tend to run engines continuously for several minutes at fixed needle in CL flight. Variable loads in maneuvers may have increased the frequency of burn-through, and too many times it was during a flight...
BTW, I think the Cox .049 conversion was Bob's first product... Sure worked well enough to kick off the great line he now offers!
