I use to love this show when I was a kid and after seeing an episode on youtube a while back I decided to give them a go.
Max, Ace & Jake - their bodies are Accelerator Suits from GI Joe Rise of Cobra, their heads are from SW and Indiana Jones figures. They have had holes drilled into their legs, arms, stomach, chest and back so that the equipment can be attached.
Equipment - Tidal Blast, Sling Shot & Sky Knight are a mix of SW toys, 1/35 tanks parts, 1/72 tanks parts and 1/72 airplane and Apache helicopter parts. Once all the equipment was put together both the equipment and figures where painted and weathered using Vallejo and GW paints
