On the SU-152 the resin printed pieces I got were a little soft IE: not fully cured. Dealing with those printed rivets is a bit of a PITA, but I guess it makes it easier to sand the flat parts. :)

Hey, my experience with parts made out of this resin (from a few different sources) is thats just how it is. Thats definitely one advantage, I think they're worth the effort compared to the original version with them printed as one piece.

I must be a glutton for punishment as I've got arnoured models tusk 1 kit for my taimya abrams and that has even more rivets.

Hey Tom,

You'll have fun with the Abrams tiles. The Abrams Armored Tiles outer plate are held in place with 8 bolts and 6 rivets per tile and there are 32 tiles per side. Luckily only 31 have bolts and rivets. :haha:

I dunno how you guys have the patience to do the ERA and slat armour but kudos it looks awsome!

Hey folks, this build has been locked into the long grass for a while waiting for parts and inclination to crack on with it.

There were some detail part additions that I wanted to add, around the mounts for the turret armour and a couple of other details such as the cable drum holder.

However the main thrust of the work required is electrical. I initially did an instal with a regular tk60, however after I'd done a tk60g2 install on a tamiya abrams and I was that impressed that I decided to do the same thing needed to be done one my challenger.

Something that was raised was being mindful about cables being twisted. I needed a slip ring which could handle motor power but couldn't find anything like this.

Happily Stanley at rctanklegion has come good and has one in specifically for tamiya modern tanks. It has 4x10A channels and 12A channels. This allows for the motors, rotation, engine deck switch, speaker, head lights, indicators and 2 spare should the be needed later.

Wire hygiene isn't generally my strong point but on this build with all the electrics in the turret I pushed myself to be as neat as possible here.

Here's the wiring within the hull, on this tank there is a good deal of space within the hull, but due to the position of the recoil in the turret being off centre there needs to be some room left for the wiring to move around the turret centre.

I've also made up a speaker box in the front integrated into the hull, like I have done on my chieftain.

On the turret the tk60 was installed in the bustle with the Rx along side on one side and the gyro on the other side. There's also a volume control. Wires were all put into conduits depending on where there were going to on the board. I also added some side plates to keep wiring within the turret and make it easier to attach the turret top.

Some photos of the lighting. I need to add the beacon light to the turret as well as adding some tamiya red clear to most of the white LEDs

Something I'm still waiting on is the Clark rotation unit with the engine deck level sensor. Currently I'm using metal rotation unit, this is a little slow, especially on 2S. With the Clark unit this speed will be increased greatly which really helps which the stabilization. I still need to dial this in on the elevation servo too.

Yay! :clap: :clap:

Tom,

You've got it working pretty well.
Looks way cool with azimuth locked and "dancing" around! :thumbup:

Thanks to your tip on the Slip Ring, I'm getting closer to having mine ready to power up in the Abrams.
