Think you will like the new model as and when you buy one. Very sweet and quiet runner straight out of the box, so properly RTR. The weight at 330g, (just over 11oz) balanced at the centre of the coupled wheelbase promises well for traction, not far short of the first split chassied version which for all the terrible racket they often made, would pull a proper size train..... list price for the 2 BR models available is £229.95 which is steep but may actually be worth it.
An aspect I really like for testing purposes, the loco runs independently, no need for the tender, despite the plug in connector. That's going to go the moment the loco has passed acceptance testing, bags of room for a proper rigid drawbar to reduce the combined loco and tender wheelbase by 3mm, which is scale..
Quite a lot more to do on this model, rear cab windows to go, slightly modify the smoke box door so the annular rivets aren't set too far back, remove the speaker and install extra weight as possible, fiddle around inside the Cartazzi frames, if the flanged wheelset requires it for 30" radius curves. Very worthwhile as the overall appearance is right, the correctly shaped boiler does make a difference.
