I like the X mounts only b/c they are easier to connect to the firewalls, unlike connecting motor directly.I have abandoned the "X" mounts as being too easily bent and unreliable when straightened.
To mount a motor that usually mounts using the "X" mount I use the "X" mount itself as a template to drill holes in the firewall. I then screw the motor directly through the firewall.
In a bad crash the firewall is destroyed where normally the firewall and the "X" mount would be destroyed or severely damaged.
There is an added benefit as I can fit slightly heavier and more powerful motors because without the "X" mount the engine installations are actually lighter and the planes easier to balance!
Just what works for me!
Have fun!
