After purchasing the Dark of the Moon Ark, I had to make a Decepticon Titan Masters War Ship.
I purchased a Transformers Prime Wheeljack Star Hammer, "borrowed" more Legos from my son (he's 5, how will he know) and created a Titan Masers cockpit and added some Decepticon stickers and now the space battles can begin...

 

The stuff on the chair is a little putty so they don't fall out during high speed flights

 

How fun! Looks like 3 titan masters can fit in there pretty comfortably. Nice job.

 

Nice. I didn't see much use for these Prime playsets for me in the past, but this makes me want to look into buying them. I wonder how well that one Optimus mech suit thing would work with the Titan Masters too.

 

I've got one and it works with titan masters pretty well. I could sell it to u if u want. I'm in the uk though.
