'Soft' e-motor mounts

Post by Wayne_H » 12 Jan 2020, 03:50

Probably not new but worth (re)sharing :ugeek:

I've used this method, or variations, of soft mounting for a while now - works great with out-runners up to 2212 size. I use an ali cruciform mounting plate to get both the plate/motor mount rigidity and sufficient moment arm to the mounting screws. 5mm rubber grommets or rubber rings are positioned on the mounting screws between the ali plate and the firewall. As an added precaution to prevent excessive tightening/squashing of the rubber, I insert a small brass servo mounting bush in the rubber over the mounting screw(s).

Then, simply mount the ali plate north-south-east west. Tightening the bottom mounting screw gives more down thrust and tightening either east-west screw changes the side thrust. Simple & quick adjustment on the field when needed 8-)
