Tamiya Russian Heavy Tank KV-2 Gigant - Full Option Kit - 56029 (Radio Controlled Model Review)

  Released by Tamiya on October 21, 2009, the Russian Heavy Tank KV-2 Gigant (#56029) is the Full Option Kit version, with a battery, charger and 4-channel radio system included.

  A front-mounted double gearbox, with two electric motors, operate together or individually to produce forward/reverse running and pivot turning. Metal torsion bars and suspension arms combine with the wide tracks to smoothly absorb bumps and dips in the terrain and provide high manoeuvrability. In addition, realistic engine sounds accompany the tank as it starts up, drives and stops to idle. The main gun can be elevated, depressed and swung to the left and right.

  When the Soviets entered the Winter War, the SMK, KV and a third design, the T-100, were sent to be tested in combat conditions. The KV outperformed the SMK and T-100 designs. The KV's heavy armour proved highly resistant to Finnish anti-tank weapons, making it more difficult to stop. In 1939, the production of 50 KVs was ordered. During the war, the Soviets found it difficult to deal with the concrete bunkers used by the Finns and a request was made for a tank with a large howitzer. One of the rush projects to meet the request put the howitzer in a new turret on one of the KV tanks. Initially known as 'Little turret KV' and 'Big turret KV', the 76-mm-armed tank was redesignated as the KV-1 Heavy Tank and the 152 mm howitzer one as KV-2 Heavy Artillery Tank.

  This model comes with metal bushings, that after a short while, when dust and grit get into them, can actually wear into the metal drive shafts that spin in them - we recommend these should be replaced by a full set of steel shielded ball bearings ASAP.

How to put on Decals

   After spending lots of time and effort to paint your bodyshell, you come to the point where you make it look good by putting on all those flashy decals, but before you rush in with the scissors and start cutting, there are a few things you should do first.

   Good preparation is key to a perfect job, so before you do anything with your decals, you must first of all wash your hands, and then make sure the bodyshell is clean and no oil or grime from your previously grubby fingers remains on the Polycarbonate Lexan surface. Methylated spirits is the thing to use, or failing that, use one of those wipes you use for your computer monitor screen.

   As the body shell dries, you can carefully cut out the decals from the sheet. Do the big ones first and leave the smallest ones for last.

Wheel Caster Explained

   Caster is basically the angle the steering kingpins or steering pivot points, leans back in relation to the horizontal when viewed from the side of the chassis.

   To test the effectiveness of your cars caster, place your model on a flat surface, point the front wheels straight ahead, and push the chassis over to one side to simulate body roll when cornering. You will notice that as the car leans over, all four wheels also lean over in the same direction. Tires provide the most grip when the wheels are perfectly vertical and the full width of each tire is flat on the ground. Body roll pushes the wheels past the vertical and reduces the amount of tire contact. Now, if you turn the front wheels as if cornering, and again push the chassis over, you will see that in this position, the front wheels are now more vertical, giving you better ground contact and therefore improved grip.

   Another effect of caster can be seen by disconnecting your steering servo and pushing your car along the floor. Because of caster and the kingpins leaning back, your car will naturally roll straight ahead.

   Obviously, the more body roll your car induces, the more positive caster you need to counter it.
