None too shabby! I think that you have built before... Very nice. Was the armoured conn part of the hull/kit, or aftermarket or did you build it from scratch? It appears to be one piece. Very nice detail.
I have always wondered about "free wheeling shafts. It seems that the only time the out wheels would be seen is when she is out of water, where as in water the drag created by them would be very detrimental. If they are just for scale appearance, seems like threading them on would save a lot of battery power and give you a faster, more responsive craft. No criticism intended.
