Hi Richard, Thanks for writing in! What can you tell us about LiPo batteries? I've seen some crazy fires on youtube - are these common? How would you hook up...
Chris, I agree that currently a lot of the noise comes from the prop. - but this can be very significantly reduced and should be our aim. The three major...
I'm glad you ask about lithium polymer battery fires, yes they will catch on fire if over charged, if you charge the battery over 4.65 volts per cell it can...

... Boyd - thanks for this... the pounds of thrust figure. I'm interested in electric air props, but on the water, not aloft, so forgive me if I'm OT a bit,...
130 pounds of thrust is the minimum needed for me personally to spend money on any e- ppg. It is just enough for aggressive, low flight at my weight and...
