I used the Hangar 9 mount on mine. It is aluminum or some sort of alloy. Much stronger than the stock DP mount albeit it a bit heavier. It is the same mount they supply in their 1/4 scale planes but it is available seperately through them for $10 - $15. I have also used the Dubro aluminum mounts with the rubber isolators on this size engine with good luck but do not find them necessary for the $35.00 they get for them. they also require maintenance as the rubber wears out. Hope this helps. If you have not seen these mounts let me know and I can email a pic. cbk
