RE: DF Hawk \ Turbax 48 fan
The plane you won is just like the Red Arrows versions on Ebay. I have one of the earlier ones and to be quite honest, I like it.
You can fit a Dynamax in the airplane. Mine is outfitted with a Turbax shroud using cut down Dynamax blades and an OS 65.
The Turbax is a tad bit smaller than the Dynamax.
