oups, I didn't express myself properly... I had just woke up 10 minutes ago :-)

The engine mount that came with the plane is only for the evolution engine, the holes on the metal engine mount is too wide compared to the holes on my engine (OS LA .46). Therefore I really can't use the engine mount that came with the arf kit. And the holes in the firewall and drilled for the evolution engine mount.

Now I have another engine mount, I believe it's a great plane engine mount, but the holes of this engine mount does not allign with the pre-drilled holes on the firewall.

I took pictures, but my laptop is acting up and I'm having trouble downloading the pics.

Let me try to upload them since pictures are worth thousands of words!
