New Engine Mount


After trying a number of different engine mounts over the past 2 years dad and I have finally had a go at making our own.

The concept was basically adapted from the mount used by Suzuki at CAOCC. With a shock absorber similar to a YS mount. The outside isolation rubbers mounted to the 4 mm carbon base plate are 70 duro rubber (soft) with kevlar insertion. Where ours is different us the centre rubber is nolothene (as used in car suspension). The nolothenes rigidity stops the motor from moving forward under high rpm and allows a reliable low idle.
The shock is a Tamiya hop up part and I have used Losi 50 grade suspension oil.

Overall I'm very happy with this mount although it is only 10 flights old.
