RE: Which electric motor for a 7" prop?
yes...inrunners are better for smaller props... I always thought innies were better.....
Hmmm.. I don't have much experience with the cans... but if it helps... I run a Mega 1615/4 on a Zagi and it screams... I ahve never tried a 7" prop, but with a 6 x 4 prop it runs very nicely...
5.5 x 4.5 is the best for me, but the 6 x 4 is nice too
I use a Kokam 2000mAh battery with this setup
