Martyn Posted April 15, 2022 Share Posted April 15, 2022 Hi Getting back into model flying again & have quick question. Purchased 2 graupner 12x7 props for my O.S 55AX & i'm unsure if these are for electric, not IC? Can someone please confirm...... Many thanks Mart Quote Link to comment Share on other sites More sharing options...

John Lee Posted April 15, 2022 Share Posted April 15, 2022 Yes, the Graupner 1316 series have been available for 30 odd years & were originally designed & manufactured for IC use. Good sturdy prop, albeit not quite as efficient as some later designs. Quote Link to comment Share on other sites More sharing options...
