Buzz,

nice bird. I won't comment on the retracts but will on the engine.

To me, the Webra is the perfect engine for the model. Not only is it period correct but it also is model and designer correct. Although Hanno put his pipes under the wing with SE Webra Speeds, the RE Webra Racing has a tad more power. They can turn an APC 11x7 just shy of 15K on 10% fuel and a Dynamix carb with proper pipe tuning.

my next choice would be the Magnum but nothing quite like an Austrian engine in a very famous Austrian classic!

My 2 cents worth.
