brfc7 Posted March 22, 2022 Share Posted March 22, 2022 (edited) Managed to break one of the folding prop blades on my HobbyKing Super Kinetic while putting it away (Doh) Had a look on HK website and a pack of blades is discontinued but you can get the whole prop assembly but only from global warehouse. Thought about using a different prop but there isn't any markings on either blade to say what size/pitch they are. Anyone got any information please or even have a spare blade I could buy????

Denis Watkins Posted March 22, 2022 Share Posted March 22, 2022 Measure the Diameter Baz, then we can look in the ballpark for the pitch. There will not be too many sizes of pitch to eyeball for the closest match Quote Link to comment Share on other sites More sharing options...
PatMc Posted March 22, 2022 Share Posted March 22, 2022 Baz, what's the length of one blade from pivot hole to tip ? Quote Link to comment Share on other sites More sharing options...
brfc7 Posted March 22, 2022 Author Share Posted March 22, 2022 Roughly measured the total prop assembly is 7” so as a sports model it’s probably running a 7x5 or 7x6. a single blade from tip to mounting is 3” Baz Quote Link to comment Share on other sites More sharing options...

I've also got a pair of unknown make (& quality etc) that measure 3 1/8" tip to pivot & about 6mm across the shoulder. Will you be at the field tomorrow ?

brfc7 Posted March 23, 2022 Author Share Posted March 23, 2022 I wouldn’t mind trying the Graupner ones Pat. Not sure if I’ll get today but if you do have time to drop them off at hut you could stick them in a bag with a piece of paper in with name written on and pin to notice board. Get yourself a fly while there as already 4-5 at field. baz Quote Link to comment Share on other sites More sharing options...

PatMc Posted March 24, 2022 Share Posted March 24, 2022 Let's hope the prop fits the yoke OK. I didn't fly as I had some shopping to do. The wind's forecast to good for a lightweight sloper at Collywell Bay in the next few days I will try to get back flying then. Quote Link to comment Share on other sites More sharing options...
brfc7 Posted March 24, 2022 Author Share Posted March 24, 2022 Evening Pat, I had to cut about 2.5mm off the root of the blades to fit in to the existing hub but had two flight this evening as the sun set and she flew great ?????? I owe you a pint. baz 1 Quote Link to comment Share on other sites More sharing options...
