Geoff Smith 1 Posted March 5, 2011 Share Posted March 5, 2011 Hiya all. 2 things that I need clearing up. (1) What is the difference between 'Fast & Slow' Props. (2) Will Cling film be ok for using between plan and building board. Cheers Geoff Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted March 5, 2011 Share Posted March 5, 2011 Hi Geoff, sorry cannot answer No2, but you will find a lot of gen. on props if you put "props" into search box top l/h of page. Cheers Quote Link to comment Share on other sites More sharing options...
Malcolm Fisher Posted March 5, 2011 Share Posted March 5, 2011 Cling film might be Ok but it's a bit flimsy. Polythene is better IMO. Malcolm Quote Link to comment Share on other sites More sharing options...
Bravedan Posted March 5, 2011 Share Posted March 5, 2011 1. My definition........A slowfly propeller is designed to give thrust at low airspeeds, is usually paddle bladed, and low pitch, designed to give thrust at the low end of it's rev range.......used for funfly type outdoor and indoor planes......A "fast" propeller (more usually called "speed", etc) is designed to bite the air with minimal drag at high rpm for high thrust at the top end of it's effective rev range. (the preserve of flying wings, pylon, etc.) 2. Not in my opinion, as said, polythene sheet Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted March 5, 2011 Share Posted March 5, 2011 The backing from Solartex is a great plan protector, otherwise Balsa Cabin sell a plan protector which is supposed to be excellent stuff, though haven't tried it yet myself Cheers Danny Quote Link to comment Share on other sites More sharing options...
Geoff Smith 1 Posted March 5, 2011 Author Share Posted March 5, 2011 Hiya all. Thanks for this, both questions answered and understood, much to my surprise. I'll have to get the hang of using 'search' the prop question was easily answered there. Cheers my friends. Geoff Quote Link to comment Share on other sites More sharing options...
