It'd be great to find one of these one day.

There a single motor version on eBay ATM, but not sure if it's able to be converted with a Tamiya 70097 Twin Motor Gearbox?

Well, yes but it would require extreme modeling skills to do. I did a Lindbergh M48 using that 70097 gearbox, see link below

viewtopic.php?f=33&t=28977

1.There are a few problems to overcome with this conversion, That gearbox is BIG and barely fits the chassis and may require modification to the chassis. It barely fit the 1/35 Lindberg M48 and I did have to cut on the chassis a bit.

2. The Tamiya motorized drive sprockets from the SM motorized M60 (or any Tamiya model) will not fit the hexagon shaped axles of the 70097 gearbox. If you manage to use this gearbox in a 1/35 model it would only be the second one that i know of mine being the first.

I really do not know why Tamiya made this very smooth gearbox impossible to use

Also why is the Tamiya 1/35 all steel gearbox not available for resale? Not even a clone is available.

jimbo, if suggest you get a Academy motorized remote control M60-A1. It is nearly identical to the Tamiya model and has a very smooth gearbox which has Tamiya compatible drive sprockets and with minor mods could be used in some Tamiya Tanks. I bought two from ebay. $35+Tax+Shipping.

Better get a couple before they are gone. Below is a link for that Academy M60. I highly recommend this 13271 model kit.

You can find "Tamiya 1/35 motorized remote control" tanks on ebay by using the search words in the parenthesis. or "Academy 1/35 motorized remote control"

Be careful that it is a 1/35 scale model as some of the ads are misleading. They say 1/35 in the ad but if you look at the pictures of the box, some say 1/48. I do not care for 1/48, that is too small even for me lol.

By the way, I paid $108.00 for my M60 Tamiya motorized remote control Tank from ebay. That sounds like a lot but I have seen them go for $180. You just have to wait for the rite time to buy. It is a lot of money but, considering the time and work that is required to motorize any model it is well worth it to just buy one that will set the standard from now on. Anything less than the 1/35 Tamiya or Academy gearbox is inferior IMO. There just is no substitute at this time.

Funny you should say that - I've just purchased the Academy M60A2 13296 kit!

I've already got this on the back burner too.

So that Tamiya type 10 would be a Scale Model to motorized RRC using the gearbox shown in the picture? Looks like it physically fits the chassis. Could you do a side shot of the axle coming out of the chassis?

Here is a ebay link for the motorized remote control M60 A1

The M60A2 13296 kit you mention is not motorized. For a few dollars more you can get the motorized M60 A1,

Correct, I needed to cut off the mounting tabs and it's just resting on some Blu-Tack at the moment.

My plan is to create a solid mount for the gearbox and fill the drive sprockets with epoxy, before drilling the shaft mounts.

It works well in my head anyway...

Yes the position of the drive axle will work. This is a critical factor. the hexagon shape axle requires some thought on how it can be interfaced with a drive sprocket in some fashion that is not too hard to implement and is repeatable.

Yeah - found that one, but I don't like the M60A1

If I can't use the Tamiya gearbox, then I may go and get the above as a donor as the hulls are identical.

I was going to drill through the sprocket and axle to use a long M2 screw to ensure a solid interface. It's not particularly scale, but it'll be covered by the tracks 95% of the time!

Would like to see that when you get it done. Sometimes you have to get creative with the drive sprockets as far as mounting goes and is the most critical factor in a motorized RRC Tank conversion.

Yes I often buy models as donors for others that I like better.
