We’ve received in some engine mounts for the Polini Thor 250. These mounts have the advantage of allowing direct attachment to the firewall — with a couple of caveats, which I’ll get to. It’s all amazing light and strong.
The Mounting plate is CNC machined and comes with rubber bushings to attach to the motor and to the firewall.
Here’s the caveats:
1) This motor is so light, you’ll need to be wary of Center of Gravity issues.
2) The installation is so small and tight, you may need to mount the motor 4 or 5 inches away from the firewall in order to have the correct placement of the propeller relative to the cowl. This may be done by using aluminum rectangular tubing to ‘extend’ the firewall forward. (Not described here, but eventually coming.)
Not shown is how to mount the radiator or the water overflow tank. (We’ve previously posted many pictures of the radiator on the ProCub / Polini installation.)
