This one is same seize as Hanno Prettner Dalotel TOC 1978 version and is scale 1/3, available as ARF.
Yes this DalotelRC model can probably be used asa pattern plane but suchlarge planes was used at the special competitions Tournament Of Champions (TOC).
You did not say price range and the 1/3 scale Dalotel ARF is not cheap. Add on top of that also the retracts.
But it is made for a 50-55 cc gas engine.
