They look okay - and as you say metal gears/shaft which is useful.

Bit slow.... I think I would go with the 3010s on the 50 - ample torque, faster, and lighter...

Put the 140 together for the first time today....everything seemed to fit !

Still got some work to do to finish it but will have to do that in France now - Van is packed !

Now that I have the engine on the model etc, I am feeling very positive about the ZN engine mount....feels just right n the flexibility front. Hatori system looks good too...

Saw the other C140 today too now its finished...(in the same van)... stunning with the graphics on !

Havent a clue what mine weighs, will take scales with me ! but it feels pretty light..
