tommy Posted May 17, 2015 Share Posted May 17, 2015 HI When ordering folding props do you take off the spinner size to get the right diameter for your motor.It is my first go at setting up a electric glider Quote Link to comment Share on other sites More sharing options...
Dickw Posted May 17, 2015 Share Posted May 17, 2015 No, the diameter of a folder prop includes the spinner, so for example a 10x6 prop is only 10" diameter when mounted on the spinner. To be more accurate it includes the size of a nominal spinner, so for example the quoted diameter of some makes of folding prop are based on a 40mm spinner.

Bill_B Posted May 17, 2015 Share Posted May 17, 2015 There are many different shape and size of yokes to accommodate various sized spinners, and things get a bit more complicated with 3, 4, and 5 bladed props. However, as an example, each blade of a Graupner 12" x 6" folding prop is actually 5.25" long from tip to the centre of the bolt hole. This means that a 1.5" yoke is required to achieve a true 12" prop arc. The problem is, a 1.5" yoke may not be suitable for the spinner diameter required for a particular model.

tommy Posted May 17, 2015 Author Share Posted May 17, 2015 Thanks for the reply.I have a 44mm yoke so with a12*6 prop it will be a more than a12*6,I can check it with a watt meter Quote Link to comment Share on other sites More sharing options...
