Just completed this one for the "Turning Japanese" GB, which was an absolute blast to participate in. The Hasegawa kit is excellent, overall, with outstanding fit and good detail. However, I added a few things to the kit, as well. The additions/modifications were...
* Yahu Instrument Panel.
* HGW seatbelts.
* Master brass cannon barrels.
* Wires, hoses, etc. added to the cockpit.
* Added sparkplug wires and hoses to engine.
* Riveted the entire airframe.
