I ordered these sentinels a couples of weeks ago from FRP Games and DogStarGames through Amazon (thanks work for that gift card!). Although I normally like to buy things from my LFGS, they don’t take Amazon points. I would recommend both of these stores if you do buy online, they both shipped within a day and were in my mail box a few days later.
Anyway, onto the pictures!
Two heavy sentinels armed with my favorite, non-Apocalypse weapon: plasma cannon goodness! I actually got these models because I like how the heavy sentinel looks and the fact it can mount up a plasma cannon is extra bonus points. It did take me a while to figure out how to glue the legs together. The legs are fully positional which is great to pose the model (and you can see some of the variation possible in my models here) but it makes it hard to glue it together. I found the best way was to glue the feet to the base as far to each side as possible, glue the upper leg to the hips and glue the two halves of the mid leg together (obviously connecting the upper and lower leg pieces). This allowed the model to still have some variation of movement possible to finish the pose, but made it easy to drop some glue at the ankle and each end of the mid-leg and let it dry.
I also built two scout sentinels. They are currently mounting autocannons but these (as well as the plasma) are simply sticky-tacked in place so I can paint it and possibly magnetize it to enable any of the weapon options. The crew are also not glued in place and since I opted to not include the roll cage they are easy to slip in and out. Some spiky bits give a Chaos flare along with the head from the vehicle command sprue. The scout sentinels still need the rock layer glued down before priming but are ready to join the mighty ranks of the 14th Grand Company.
I do need some suggestions on a paint scheme for my vehicles. I was thinking of something similar to the Modian tank in the IG codex, but have also seen some great looking models painted red/black. The problem is that both of these color schemes clash a bit with the orange of my main troops. Any thoughts?
