Teus has an old Saito 52 in his and it flies well. But he said he'd prefer on of the Satio 62 (same exact size as the 56). I already have the Saito 56 (from my deceased Legionnaire), not to mention the Flair 110mm wheels and the Vickers and Lewis gun kits, so I''ll just stick with the 56.

On the plans, measured from the bottom of the engine mounting brackets to just under the surface of the top deck is about 85mm. The Saito 56 fits, but just barely.
