I have the Taigen T-34 hull and I liked it a lot when I first got it, but found that the hull did flex and the suspension splayed out. This was fixed with some epoxy, and was documented here.
I was hugely into Nscale trains, and said the same thing about IR standardization when I arrived on this board. The hobby, for the benefit of all, needs to develop an IR standard, so all brands play well.
Most of the third party developers have adopted the Tamiya as a Basic standard. Heng Long went their own route, and then Taigen went a completely different route so that Taigen don't play well with HL. This is very unfortunate as you isolate a like minded group into different camps of IR.
Very similar to the old coupler discussion back in the day before the NMRA made a standard for Couplers. This allowed different cars to be hooked together regardless of brand. It would be nice if all manufactures could agree on going one way on this IR thing.
As an N Scaler from Edmonton you should enjoy this CNR GMD1
Or this N Scale Steam meet.
