RE: brushless formosa help
I flew my Formosa with a Himax 2025-4200 with 2S 1500 and 11x8 SF prop. Good increase over the stock set up. Nice verticle up to about 150, maybe 200 feet. After I wore those batteries out, I replaced them with 3S 2100 and propped to 10x8. This set up doesn't push the batteries hard and the Formosa goes verticle as long as you want
