Hi,


My last update to the motor mount has been to cut a front mounting plate out of aluminium to replace the old one made of fiber glass. The plate added 4 grams over the old one but with the increased cooling it should be worth it. The plate is cut from 2mm thick 5xxx alu alloy. 1.5 mm is probably strong enough but 2 mm was what I had laying around. I will add some Thermal paste used for computers between the motor and the alu plate to optimise heat transfer.


I donīt holt an Auto Cad licence any more so my hand drawing will have to do if some one would like to copy it.




Br,
Henning
