That's a nice little model but I'm sure that isn't the 6x6 Graupner the Poms use.
I'd guess that the right one would be the 6x6 Graupner "Grey". I tried those electric props and they were far too flimsy.
Pity about the MVVS as well. They're well within the rice pudding skin pulling power curve.
I'll do the plan tonight.
