Tamiya Jagdpanther - Full Option Kit - # 56024 (Radio Controlled Model Review)

  Released by Tamiya on December 1, 2007, the German Jagdpanther Destroyer (#56024) is the Full Option Kit version. Requires a battery, charger, 4-channel radio system, paint and glue to complete.

  The front-mounted gearbox contains two Type 380 motors that can 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.

  The Jagdpanther (German: "hunting panther"), is a tank destroyer built by Nazi Germany during World War II based on the chassis of the Panther tank. It entered service in 1944 during the later stages of the war on the Eastern and Western Fronts. The Jagdpanther design combined the 8.8 cm cannon of the Tiger II and the armour and suspension of the Panther chassis, although it suffered from the general poor state of German ordnance production, maintenance and training in the later part of the war, which resulted in small production numbers, shortage of spare parts and poor crew readiness.

  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.

Electric Motors for RC Models

   Choosing the right Brushless motor for your needs can be a daunting task for those new to Radio Controlled Models. If you have a local club perhaps you could ask some of the more experienced members for their advice, but a little basic knowledge about the subject, so you know what questions to ask is always useful.

   All Brushless motors are rated by Kilovolts (KV), and is an indication of the revs per minute (RPM) that particular Motor can attain running freely, under no load conditions, per Volt of input.

   For Example: To calculate the Maximum RPM of a Motor listed at 4000 KV, connected to a 7.4 Volt Battery, simply multiply the two: 4000 x 7.4 = 29600 RPM.

   The two main types of Brushless Motors used in RC are Sensored and a Sensorless Motors.

Bearing Seals

   If you were to ask anyone with a modicum of experience in RC, they will tell you that the best modification you can make to a basic RC model, is to add a set of ball bearings.

   Quite a few of the entrance level models at the time this article was written, come with plastic and sintered brass ring type bearings. If these bearings are installed in the model and coated with grease as advised in the car manual, dust and grit can be caught in that grease and be dragged into the bearing where it can abrade the shaft that spins in it and it won't be long before it becomes a very sloppy fit, causing all kinds of problems.

   But what should you look for when buying bearings? There are a number of types of seal used on ball bearings, and there is much debate concerning which is the best for RC.
