KV-1 Project.

Received a lot of good help from the forum so I thought I put back in by posting a running commentary on mods/upgrades I plan for my non smoke & sound KV-1.

The starting platform is a KV-1 non smoke & sound with metal tracks, drive, idle wheels & gearbox. I bought it off eBay as an ex-display which meant the turret hatch which hides the firing switch had come off, everything else worked.

Having S&S on my other two tanks I missed it on this one, a quick look inside and looks like easy transplant as all the switch, volume holes where there plus studs to fix speaker, and other bits.

So my list to do is –

* Transfer RX18 and other bits into the tank.
* Fix hatch door.
* Install metal exhaust outlets and rig smoke unit to these.
* Install tail light.
* Install LED machine gun.
* Install cooling fan to RX18 board.
* Modify smoke unit so is speed proportional.
* Modify gearbox so is low ratio.
* Possibly install second battery for more power and extra weight.
* Possibly move switches and stuff from bottom of tank to an easy to get to hatch on the top of the tank.

So some of them are straight forward where as some more involved.

Hopefully should start them soon so will posts pictures when I do.

Good man Tankbear ! - If you are going for gearboxes , the new HL brass 3 to 1's are good . ( the long shaft ones )

    Next job metal exhaust.

    Image

    With a bit of wiggling the plastic ones came out, had to drill holes out a bit to allow new ones to fit.

    Image
    Pushed into the body.

    Although when fitted one of them fouled the motor.
    Image
    Added bluetack so could see where abouts.

    Looks like I need to move the motor, which will mean the smoke unit will need to move also.

    I'll keep you posted.

      That's nasty Tankbear 8O I think the problem is that the working exhausts were designed for the Tamiya KV , not HL .
      • I just checked my two set ups , 1. Asiatam gears may be the same or worse because the top motor is centrally located :thumbdown: i have the metal hull etc . ( it comes with a twin pipe set up for a smoker , if i do ever fit one it'll be an upgraded type ) and it doesn't have the bulkhead like the HL , so a measurement is tricky - but I'll take the moulded exhausts out later and check for you .
      2 . Here are my HL 'boxes , fitted into my old HL hull , the gap between the bulkhead and motor is 5-6mm , would that be enough ?

      Yes quite straight forward, most of it is plug-in arrangement. Only cables I had to cut and join are the motors and power, plus the smoke switch. Plus all the slots for switchs and volume etc already in the hull so just had to find a load of small screws to fix them in.

      Welsh Dragon Models sell the RX18 & leads kit for £20, plus you need speaker and smoker.
