^^^ that kind of weight was what I was running into with the Guzzi twin. I have the reduction unit they used on the Hunter drone in the Mideast. That engine was 63 horsepower. Just too heavy. Inverting one and using a dry sump to get the prop in the proper location cut a *lot* of the weight off, but it doesn't make enough power at 3200. That made the Verner a no brainer.
