mark, i worry about people in our industry doing anything (chipping, sawing, rigging, climbing, cranes, etc.) we here about so many accidents. most preventable, some not preventable. i worry about people with the attitude: i'll just shove the rakings the rest of the way in the chipper with my foot!!! cranes only "raise the stakes" of safety. an unsafe attitude w/crane= catastrophy. however i wouldn't be worried about you and a few others carefully using remote because (like me) you probably climbed and chipped at an early age, started doing crane removals in your early teens. or anyone with good/safe attitude, skill, and exp. my kids wanted to climb at age 2.
