Looks, runs, and sounds nice. However, no articulated chuffing is a huge mistake IMHO. Still it is very tempting to pick up a couple. If there were more FasTrack available I would probably be giving myself some Christmas presents right about now :-)
The new electronics and mounting looks fantastic. Nice job Jon. Any chance we could see a non-articulated offering soon? It looks like you have reduced the size of the components quite a bit.
