While it's the same capacity, a .61 sized nitro two stroke should have a little power advantage as I understand that the really small gassers like this lose out slightly in power to their two stroke nitro cousins.
Not to mention that they are heavier with their ignition and battery requirements when installed in a 'smaller' aircraft where weight reduction is perhaps more crucial.
That said, I have a DLE20 in my H9 '60' sized 65" P51 mustang, and of course am running gas in my 73" Sbach342 as I like the idea of cheap & clean flights without getting oil all over my airframes, well that and I "PERSONALLY" am not a fan of electric as I feel it lacks soul.
The only nitro model I have now is my 50 sized heli.
