Motormount for Graupner Cirrus, Cirrus 75 and Cumulus pylon

thingiverse

This is another motormount for original Graupner Cirrus and Cirrus 75 pylon. Its more elegant and more forwarded. Maybe this is better for the center of gravity.. Designed for the Turnigy Aerodrive 3536 1050kV on the high quality, original aluminum Graupner motorpylon meant for a little nitro engine on a pod made out of wood for the Cirrus 69, Cirrus 75 and Cumlus. I could bend the aluminum to look better but I did not want to do that. So its a bit square. I dont mind. There's a hole where I glued 3.5 mm steel pin so it will never brake there or you can glue something else in like glassfiber rod e.g. The total hight of the motoraxis to the fuselage is far enought for using big folding props up to 13 inch.I kept the frontside square so you can glue some balsa to it and make it more aerodynamic. Then sand it all and use filler/primer and spraypaint to give it a color again. I didn't make holes to attach the mount to the aluminum pylons. You must do that yourself with a 3 mm drill but better with a piece if hot piano wire or thin nail. Printed it in PLA and is really strong enough. You can also print a 8mm thick ring if you need it for extra space in case of for sticking out axis. On the photo you can see I installed the extra ring. Happy flying
