I beleve what you are talking about is in reality one of the two clones of the of Sig Senior Kaydet that possibly has even been produced in the same factory as the other clone the Nitro planes version and the earliar arfs from Sig.

The Nitro planes version of the airpane has shown up in four identifiable version that seems to have deteriorated from container load to container load.

The latest arf version from Sig I have not seen yet but hoping it is on track. The Senior Frontier clone from World models I have not had a chance to see so cannot comment on its quality but it is a Senior and there is no better trainer as well as argualbly the most succesful RC trainer ever.
