heres my thunderclash thus far using the following parts:

Combiner wars battle core optimus prime
Renderform thunderstruck kit
Beelzeboss hosting inside (minus the chest)
Reprolabels thunderclash set

 

Nice work, love how Donetello is photo bombing in the background

 

Haha he just wanted to stare at thunderclash's butt. Only thing I wish is that there were labels for the hosting inside legs

 

Very nice. I've been wanting to turn my CW Prime into a Thunderclash. Do you have an image of his alt mode?

 

Great job!

 

Both modes are awesome.

 

Thanks!

 

Love the look of this figure. I have three of the conversions you listed. The one I'm missing for mine is the Beelzeboss kit.
Have you thought of getting Steam Shields Cannon Master Leader's Back Tubes and/or Shoulder Pads off Shapeways?

 

ive considered it, just havent gotten around to it yet, this custom got away from me a bit and im debating between finishing it or getting the fans hobby thunderclash
