Tamiya Russian Heavy Tank KV-1 - Full Option Kit - 56028 (Radio Controlled Model Review)

  Released by Tamiya on April 1, 2009, the Russian Heavy Tank KV-1 (#56028) is the Full Option Kit version, requiring a battery, charger, 4-channel radio system, paint and glue to complete.

  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.

Servos for RC Models

   Servos are found on all kinds of Radio Controlled Models. RC Touring Cars, Buggys, Trucks, Truggys, Monster Trucks, Rock Crawlers, Airplanes, Helicopters, Boats and Ships for Steering, Throttle Control, Rudder Operation and Wing Flaps.

   For complete RC beginners, choosing the right servo can be confusing, so here are a few tips to point you in the right direction.

   The standard, plastic bushed (bearings) type servos are fine to start with but come with plastic/nylon gears that can break easily in collisions. So, to protect your servo gears to some degree, make sure you have a good "servo saver".

The Importance of Balancing your Model Car Wheels

   The day I passed my driving test at the young age of 17, the first thing I did was to drive over to my girlfriends house and take her out to a long straight stretch of road close by, where the boy racers would often congregate. No one was around that day, so the road was relatively quiet. I slowly went through the gears and we were soon up to 65 with no problems, but as we got closer to 70, my hands began to sense a small vibration on the steering wheel. By the time we hit 75, the steering wheel and the whole car was vibrating wildly. My girlfriend was hysterical, screaming for me to "slow down!" I did of course and tried to calm her down.

   Back home I told my dad what had happened. He then reminded me that just the week before we had put on a new set of front tires and suggested the wheels were probably out of balance. Sure enough, after the wheels were re-balanced, at 85, 90, the car was steady as a rock and drove perfectly.

   As I got deeper into RC, that memory returned and I realised to be more competitive I would have to balance all my wheels.

How I Balanced my Model Car Wheels

   Wheel balancing equipment for RC cars is now available on line and from most RC model shops, but back then I had to make my own using the rear end of an old Tamiya F1 car.
