Gearbox

This is a gearbox for a 7mm Pager Motor, it uses a Ball Bearing for Maximum effiecency. I recomend using this gearbox with a GWS 4025 Prop. Here are the items you will need to complete it: Shaft - https://www.shapeways.com/model/edit/373670/ Gearbox Body - https://www.shapeways.com/model/edit/373669/ Spur Gear - https://www.shapeways.com/model/edit/373668/ Pinion Gear - https://www.shapeways.com/model/edit/373654/ Ball Bearing - https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9234 7mm Pager Motor - https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=12021 ( you only need one so you will have one spare) This is the propeller i recomend to use with it - https://www.hobbyking.com/hobbyking/store/__10040__GWS_EP_Propeller_DD_4025_102x64mm_6pcs_set_.html You will also need some threadlock or superglue to gold the pinion on the motor shaft
