For: CA Reinforced PistonProduct Information:
this is the one in the x series, but using a 25c lipo, and deans connectors, and its still goin. there is some wear, but that is because the AOE isnt great, i would recommend taking off the second tooth for the AOE. but its great for anything m120 and down. I have heard of people using it for m130, but i dont think it would lasst very long.
holds up to lipo
good for high speed 400fps and down
need to file down the second tooth
not ment for super high fps, but hold up fine to around 400
overall, good piston, but i would recommend something else for anything more than an m120
