Team Checkpoint and Saiko Motors

[Basher67]

Picked these up yesterday with a collection I purchased. Not familiar with any of them. I was able to find some info on Team Checkpoint motors. Silver one is a platinum maybe? Not sure about the blue label one, but I noticed it has the more common style of brushes. I could find nothing on the Saiko motors. They say G Force on them with a little pic of a dragster. The magnet strength on them is incredibly strong. I know Saiko makes drag motors, but everything I've seen is about their modern brushless motors. Hoping someone can point me in the right direction for some info on these.
