I'm trying to convince myself that it's time to get into the brushless world. I'm looking at the Mega motors in particular for the speed 400 pylon plane I have.

What do the numbers mean?
What is the 16/15/2 through 8 mean?

Any input would be appreciated.

Also - the plane is the Dynamic 400 from Hobby Lobby. It's DD w/ a 5x5 prop running on 7 cells.

Thanks!

I think they mean rotor diameter/length/# of turns.

Example: For a 22/30/3 the rotor = 22 mm diameter/30 mm long/3 turns of wire.

What mega would best suit the plane?

....and how much increase in flight times do you get by going brushless?
