Editing Warhammer 40,000/8th Edition Tactics/Adeptus Mechanicus (section)

=== Modeling Tips ===
Kastelan Robots are still derpy Baymaxes. And as mentioned before electro-priests look like ass. You might be screwed on the priests, but we do not need to settle for the derpbot 9000. 
* The cheapest and easiest way to improve their look is to simply rotate the head 180 degrees and lower them further into the torso. That will give you a much cooler domed head with a smaller silhouette, and a more sinister and inhuman appearance.
* wargameexclusive.com makes alternate resin heads for Kastelans. Or pretty cheap Penitent-Engine-looking alternatives if you wanna go that way. If you like those models, they also make a female Dominus (Domina?) and Kataphrons WITH LEGS. And a pin-up version of the Tech-Priests and some Skitarii for [[Promotions]].
* Forge World does make the Castellax which looks godly (and a little bit like the Hulkbuster) but is a tad expensive. You can kitbash a Datasmith with a spare TPD (every Admech player should have a ton left over from SC and Forgebane boxes) and some Skitarii/Sicarian bits. Keep in mind when (if) the 30k dataslates drops you will need to do some work to make your Castellax and kit-bash Kastelans stand out from each other. 
* Or if you have some Kataphron bits left over conversions may solve some problems. Flip the head around to the smooth side, leave the thigh armor off and your Kastelans start looking better. 
* Gluing the barrel of the Heavy Grav Gun in place of the Incendine Combustor for a good-looking shoulder gun. If you have any Grav-guns from Space Marines left over (please say you do) glue them to the back of the Power Fists and voila. Even better, use the grav-bit from combi-weapons. Take two, glue onto the back of the fist, then grab the armor off the top of the razorback turret and glue over the grav.
* Glue the "three sensors" bit from the sensors/comms of the Icarus Dunecrawler kit onto the Katelan's face plate for the Armored Trooper VOTOMS look. 
*There's also a shapeways store for bits that resemble FW Castellax. Link here:https://www.shapeways.com/shops/stahlgeist-eisenfabrik
*New Years Open Day 2019 at Warhammer World revealed new "Ambot" sculpts for Necromunda, seen here: [https://youtu.be/I9IqHwCa62k]. A few gun swaps, as these come with wrist bolters and no shoulder cannon, and you'll have suitably bad-ass robots, finally. Just keep in mind the Ambots are significantly shorter than the Kastelan, however each Ambot kit comes with twice the amount of legs required so some converting can make them tall enough.

For the Electro-priests take some Servitors. Grabbing the Extra Arc claws and Hydralic Fists and put those on and you have electric dudes with melee weapons.
* For the Corpuscarii Priests using the Heavy Bolter Servitor and replacing the barrel with an Arc Rifle might be enough.
* Mix the Electro-priests kits with some Empire Flagellants for good looking fanatics.
* If you have any Ranger heads left over from a skitarii troops box, a bit of crafty knife work to flatten the joint can make excellent alternatives for electro-priests.
* Another option are the Negavolt Cultists from Blackstone Fortress, if you want a more creepy, servitorish look.

Blackstone Fortress comes with UR-025, an Imperial Robot model. Snap off the Assault Cannon barrel and stick some leftover Kataphron guns for Breachers.
