Here is the new C/S 70mm 10 blade fan unit. It's got lots of power as you can see. It knocked over my 11 1/2 pound breifcase full of tools and parts. Not bad for a 15 buck fan unit. It is set up with a Sapac D2842 3200Kv motor. The pack is a 4s 3300 40C Sky lipo and HobbyWing 80amp ESC. I got 1575 watts at 105.99 amps. Looks like I will need the 100 amp ESC for this one.
