RE: Dual Nitro plane engine ????
They are Kraft .61s in a belt drive reduction drive. The engines ran fine and are now made by RJL (Mecoa.com). Do they still turn over, or are they frozen? The belt drive was a disaster and I don't thnk you can still get the belt. You may find someone on ebay who will buy it, but the price is not likely to be high. (Maybe $100 for the whole set up, maybe a lot less.)
