Do it the easy Way and buy RC Kits!
RC kits are for those RC fans that are looking for something more than just racing their Radio Control models. Unlike most RTR - Ready to Run Models or RTF Models - ready-to-fly models, RC kits require a more extensive building process and tools. These models are extremely realistic and if you know the science well, then you can customize your RC kit to any degree, increasing their power, performance and appearance even.
Radio control devices date back to the late 19th century when Marconi used radio control to 'magically' guide a boat to do an audience's bidding. Years later, in the 1960s, the technology became commercialized and products began appearing for the general consumer with a focus on optimizing speed, power and performance. Electric models came and gave way to gas-powered and RC Nitro Models and engine sizes kept getting smaller, with performance getter better.
When you step into any toy store, you can pick an RC model that's ready-to-run or almost ready-to-run. This basically means that these models require no or bare minimum installation, respectively, before they can be taken out for a spin. Such models require little or no knowledge of the working parts and do not pose a challenge to even the newest users, in terms of build. However, if you feel that you are more of an expert at running RC models, then an RC kit is the way to take things to the next level.
RC kits are basically scale models of real-life vehicles that come in a completely disassembled state. It comprises of a frame that forms the base of the model. On the frame, the basic components of the model are mounted to resemble the actual thing. All RC kits are accompanied by a detailed blue print of what does what and goes where. In most cases, these instructions are detailed enough to aid you from start to finish; however, sometimes there might be instructions that leave out details of certain parts that are not included in the kit, for e.g. an engine. In most RC kits, you may chop and change the original configuration and parts as long as you know what you are doing.
If you wish to install a more powerful engine in your RC model, then the RC kit is the best option for you. Each part of the model depends on your whims & fancies. However, when making certain additions such as a more powerful engine or maybe a bigger fuel tank, you need to keep in mind the restrictions that can cause your model to crash and burn, quite literally in some cases.
RC kits come in many difficulty levels that begin from a simple kit containing all the parts or, for the more adventurous types, just Balsa wood frames. Depending on your level of expertise, you can choose to buy simple Balsa wood frames that allow you to dictate terms from the start, or better still, get some 'raw' Balsa logs and carve the frames out of them. Then you can move onto the next step of adding the engines, the motors, the fuel tanks and so on. All parts are available easily at any of the RC Hobby Stores. Depending on the performance you wish to extract out of your model, you can upgrade, downgrade or simply modify the models to suit your liking.
Some kits come pre-cut with laser, offering accurate and smooth edges while others may require you to cut them out of the wooden frame. Adding in the radio receiver, servo, and other electronic parts may require extensive knowledge of the science although all models and parts (if bought separately) come with extensive instructions to carry out the project faultlessly.
RC kits are definitely for those who are serious about the hobby. Not only do they require a great deal of skill, they also demand a lot of patience as some RC kits can take anywhere between 4 weeks to upwards of 3 months even. So get into this hobby only if you are serious about it. Once you are ready and have bought your RC kit, then just enjoy the time you spend on it, watching it evolve slowly over hours or days, till you finally convert your RC kit into a working RC model.
