Same manufacture, different model. This is the older version of this model with slightly different fuse etc. All i do know is that they are not caompatible partswise.

They do fly great though!! My stuka was a really nice easy to fly machine. I maidened and have flown a few time a mates' ESM 80" hurricane and it would have to be one of the best warbirds trainers out there.

Thanks
