Had a chance to pass a HL today, 40%-off coupon in hand. Wanted E12s...found none. Back-up plan was E9's...found none. Drooled over their new Pro-Series MPR kits, especially the 3" Leviathan. They had one each F50, G40 and G80. I suddenly realized that the F50-6 is what I'll need for the Air Serpent, so my decision was made. The motors are pretty expensive but get back down to Internet pricing with the coupon. Actually, a tad better than Hobbylinc.
Now, I need to scramble to get the Serpent flyable for this weekend' MDRA launch.
