sono in commercio dei riduttori (gear box) con rapporto di trasmissione 1:50 che dovrebbe assicurare una maggiore fluidita di movimento e
limare un po' il picco nell' EP sulla frequenza relativa al gearbox .

The MClennan boxes require removing the pinon gear from the motor and
replacing it with the pinion supplied with the MC gearbox.
Then the gearbox has to have the screw holes drilled and tapped to
4/40 thread for the motor screws and the other mounting ears have to
have the holes enlarged to fit the screws. Then the gearbox cover
holes have to be enlarged to allow the holes in the mounting tubes
that hold them in place to fit, there is a very slight difference in
the placement of these holes.
This is what is needed, but the cost of the gearboxes is comparable to
the originals and after these modifications, the original mounts
hardware will work fine.
