The KV-1 from us uses the 48mm shaft gearboxes. The HL hull uses 58mm. It can take both H/L and M/L gearbox types, but a small mod will be needed for H/L types (below).

I used Taigen low profile brass gearboxes in mine but they are no longer available.
The KV-1 is quite fast and does come with the 3:1 type gears. If you wish to install the 4:1 gearboxes you must either remove or relocate the smoke unit from the upper hull. After that you can then fit any of our gearboxes in them as long as its a 48mm shaft version.
