Ah yes the Minerva! Came in two versions the MS894A and the MS894E. The 'A' had a stick and manual flaps. The 'E' had a yoke and electric flaps.
Noisy as h3ll inside and a bit cramped in the back for the pax due to the spar running through the cabin. For the pilot it is a hilariously fun thing to fly.
The Franklin engine was carburetor fed, not injected, on the three or four different ones I flew. Starting it on a cold day was a real b*gger and more than a few were lost to engine fires on start up.
Would I ever buy one? Well I am not certain about that, perhaps not. The later replacement, Rallye 235, was more up to date and a bit less agricultural with a lyco engine. A far better machine.
