I finished up my Land-Speeder conversion to add some zippy firepower to my Marines. Speeders are cool, but I've never been a fan of the exposed crews and went poking around the internet for some conversion inspiration.
I came across this fantastic one modeled after the Diamonback from Starcraft II by fellow Dakkanought
Flinty, and I basically just copied it whole hog. The little hover feet make it look a lot more agile than just the "flying shoe" silhouette.
This is probably the most involved plasticard build I've done, and required a lot of measuring out weird angles on the computer, printing out a template, and cutting it from there. The joins are a little squadgy in places, but overall I'm pretty happy with how it turned out.
