I realise now that getting the metal upgraded Bulldog was perhaps not such a bright idea, but what's done is now done, so we have to accept that and just move on.
However we have managed to sort the top track guide rollers, and the smoke unit does work reasonably well, albeit as most here have noted it's a noisy blighter!
The Taigen Tiger 1 seems a fairly decent piece of kit for the asking price and all systems on this model work OK, so far.
Great forum with loads of guys offering experienced advice which is really useful to a Newbie.
