History

Introduced in November of 1987, the NSR 250R was the second generation of the NSR line. In what many would call the best year for the NSR line, that model year introduced many innovations that made it a race winning performer. The most significant advance was the PGM module that controlled the carburetor performance, based on input from the throttle and speedometer to adjust the carbs in real time. This was the first computer control of its kind on a Honda motorcycle. This was in conjunction with the Honda RC, or” revolution control” system, an adjustable exhaust valve that constricted outflow at low RPM and opened at high RPM to produce optimum power at any throttle setting. Added to coated pistons to reduce friction wear were larger tires to keep the bike on the road and a powerful 249cc engine producing 49 hp. I’ve never ridden a motorcycle over 125cc and I thought that was impressive!

This review is of the MiniArt Diorama with Park Wall, part of their diorama series of bases for armor models. It was a pretty easy build, and it looks nice when finished, but it did take some work and some modifications to make it look good.

First of you get a sheet of very soft plastic to use as the base. This has some very nicely done details with the pathway and some small rocks in the road. The base is marked off for where you will put the wall.

The Aircraft

The TR-1A is/was a development of the famous U-2. The U-2 is a high-altitude reconnaissance aircraft with multiple sensor arrays, allowing photo, radar, electronic, and signals intelligence. The original U-2A was developed for the CIA by Lockheed, using a fuselage from the F-104 and extra-long, glider-like wings. This allowed the U-2 to fly at altitudes well above those which could be reached by any other jet aircraft. The U-2’s ability to fly over any area with impunity ended with the development of the Soviet SA-2 Guideline SAM, which shot down Francis Gary Powers over the Soviet Union in 1960 and Major Rudolf Anderson Jr. over Cuba in 1962.

The TR-1A was put into production in the 1980s as a tactical reconnaissance aircraft. It is identifiable by the two large sensor “superpods”, one on each wing. It is identical with the U-2R, and all TR-1s have been redesignated as U-2Rs. The U-2R is larger than the original U-2.

The Aircraft

The Ju-52 was actually known as the Ju-52/3m. The 3m stands for 3 engine (dreimotor). The original Ju-52 was the Ju-52 1m which was single engine (einmotor). When the prototypes were flown, it was discovered that the plane was underpowered, and two engines were added, one on each wing.

The Ju-52 had an interesting exterior. The outer skin was corrugated, giving the skin far greater strength than a flat sheet of metal. This allowed the plane to have fewer spars and braces, so it could be lighter, which increased the cargo carrying ability. Unfortunately, the wrinkled skin also added drag, but in the 1930s there was much less interest in high speed and more interest in ease of assembly and maintenance.

The Ju-52 was known as “Tante Ju” (Aunt Ju) and “Iron Annie”. The Ju-52 remained in production until the end of the war, and some continued in service until the late 1970s.

The parts are molded in gray, black, and chrome. According to the instructions, the first step in assembly is the motor. The locating pins are small, making it hard to line up the parts. I used a slow-drying plastic glue rather than cyanoacrylate to make sure it was aligned properly.

Then I dip-painted the fenders, gas tank, carry boxes, and parts F-9 and F-10, using a special process with water and paint. I sprayed black and chrome into a five-gallon bucket filled with water, then hand-dipped each completed and prepared part in. As I withdrew the parts, the paint, floating on top of the water, coated each part in a swirling, soft-edged pattern.
