I love the Delta Plus... but I love the Delta Gundam more. Actually the original reason why I wanted to buy the Delta Plus was just so that I could make the Delta Gundam. I was sure that I wasn't the only person that had that idea and sure enough other modelers did end up making it... but it wasn't as abundant as I thought it'd be. I thought a lot of people would be going for this mod but as it turns out not many did. Looking at what the modeler below did I can kind of see why. It's not really that easy. Comparatively it is because you're making a more complex design simpler but there are a couple of things that have to be almost completely redesigned (the shield for one).
I like the Delta Gundam more than the Delta Plus because of the colour and the simpler design. It's a shame the suit wasn't fit for use during the AEUG/Titan's conflict. It would have made a great suit for Quattro to pilot but he would have stolen the show from Camille and they'd have had to call it Delta Gundam instead of Zeta.
This begs the question... what on earth would a Double Delta Gundam look like?
Perhaps similar to this?
It's not pictured here in wave rider mode but it looks cool. Very cool in my opinion.
