Electric model airplane motors started going brushless some 17 years ago. The change over was slow at first because of the much greater cost. But along came the Chinese with their copies and cheaper LiPo batteries and chargers and away they went.

The electric model car, boat, and plane  world is almost completely brushless now. Some electric brushless motors make more power than a 150cc twin engine. This is a hint into the future? We may see large brushless DC chainsaws with Lithium batteries in the future?

I consider the big electric model airplanes to be more dangerous than the gasoline ones. The reason being is that they can start full tilt instantly without warning. The electric motors for their size have more instantaneous torque than a gasoline engine. LiPo batteries are well known to burst into a vigorous flame when being charged improperly. The LiPo battery maintains its charge while setting around unused. It you draw the voltage down too low, the LiPo battery will puff and swell up. They are then no longer any good. 
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
