Guys,
It has come to my attention that some pilots are using after market motor mounts which are designed for 25x3mm motor mounting pattern.
Please be cautious of using this after market 25x3mm motor mount. If you want to use the 25x3mm after market motor mount on an E7, please be aware there is a risk of bolt failure. This after market option should only be used for sport flying on the E6 only. In our testing, we were able to to break the 3mm motor mount bolts. This option was never offered in the E6/7 Kit due to the risk of failure. Today's motors are producing in excess of 6HP and some of the motors can be slightly out of balance which can cause a failure. The E6/7 comes with a 30x4mm bolt mounting pattern in order to provide adequate support for the motor.
Please refer to page A19 of the on-line manual.
