I'm using all three sizes of the hacker A20's right now. They're real monsters for the weight and price. The 20L seems to be one of the best mini-funtana systems, using a 3S 2100 thunder power pack and a 12X6 "E" prop (NOT a spoon blade slowfly, but the narrower "E" series). I'm so excited about the value of these (low cost including all the "goodies" as stated above,..i.e. mount, both adapters,etc.) that I've got a couple new designs I'm working on for kits, specifically for these motors. One of them , at 310 squares, 31.5 span, is 7 oz with the 34S and a 2-cell 700 pack, and a little under 10 with the 28M and 3-cell pack(wanted a proper balsa indoor/outdoor plane to hit the 7~8 range and 10~12 range simply by using different power systems), and the latest, that will be kitted first, is 20 oz flying weight with the 20L, 3S 2100 pack, and 12X6 "E" prop . TONS of power. This is pushing the 20L a couple amps above hackers stated "limits", but the motor is basically cold at the end of a flight, and will hover the 20oz plane at about 1/3 throttle, and I know how conservative hacker usually is with their printed specs . Will probably try an 11X5.5 since it's got so much reserve power. I don't know the actual thrust numbers, but it's got to be pretty close to 2 to 1. I just got my first shipment of 26M and 20L combo's to sell. The combo "street prices" are really nice, at $120 for the 20L with 20 amp controller and $110 for the 26M.
