I got 2x 4.5 fans they are great the fans are balanced well. However, the cone screw is about .5 mill out of centre and they don't make a 6mm replacement shaft.

Tried a Hyperion 4025-890 in the bored out housing. See my previous review. Used 10 new Turnigy 5000, 30C cells. Turnigy 100amp esc. 112 amps 4.1Kw. Reduced throttle to 85% to give 95 amps and 3.3KW constant. Batteries only got warm. Had to strengthen fan motor mount with support cut from circuit board and glued to web. Combo powers a 13lb, 42oz per ft sq Sabre well, staggers off grass then really gets up and motors once "on the step".
