That was a common problem with the 72 Mhz radios. Much less likely with the quality 2.4 Ghz systems now out there. Even still, with the power levels we are finding on these electric models, not a good idea to take chances.
One of our club members tangled with the prop of a little Ultra Fun Jet last summer. He's OK, but his hand got sliced up a bit. These little Fun Jets have motors that pull some 40 Amps on a 3 cell LiPo. That's in the area of 1/2 horsepower.
