To play on road, you need to have a smooth track to play to start off with be it electric powered (EP) or nitro or we call them gas powered (GP). Currently, GP touring cars is rambling more than the EP touring but they do play at same places like Klang - Kota Raja, Glemarie - HPC Speedway (still under construction), Titiwangsa (much bigger track and suitable for GP) and now a not maintained Yokomo track @ Subang Jaya SS14 (more suitable for EP 'cos is smaller) and off course not forgetting the weekend make shift car park roof top track @ Atria Shopping Centre.....just to name a few.
To start EP or GP......well cost about the same but I reckon EP is much easier to start 'cos you just charge up and go zipping on the track. Need not worry much about a lot of things until you have decided to go serious.........better chargers, motors, equipments like a motor lathe, dyno, dischargers ....... aaaarrrrgh the list gets endless !!
GP on the other hand you still need to charge up the receiver packs b4 playing and you need to learn the art of tuning the engine.......if you go for the Italian powerhorse........sometimes it can bog you down. If you have decided on GP, get the Japanese engine ....ie OS.....once tuned and you don't have to worry much........just roll only

..........when you've gained experience, you may try the Italian babies.......more oooomph!!
The next on-road category.....EP actually would be the 1/18 scales and 1/24(mini Z) you could play indoor with these cars and there is only one indoor track in KV and it is in Puchong Jaya.
Another option is the 1/12 pan car. Yeah....EP too......a very rare race machine these days but hey there are some zipping around on the tracks and these thinggy are absolutely fast, able to give the 1/8 GP boys a run for their money!!
Well the next thing is off-road.......be it EP or GP, the issues are the same with only one thing extra......and ie. DIRT.......after a run your car could really look like "shit"......but if you run GP.......just remove the radio tray (where all your servos, receiver and batteries are mounted), cap the carb and hose it down baby .

blow dry with high pressure air (normally track owners would have one air compressor drivers to use), re-oil the bearings and voila!!.
Next is running cost. GP onroad being the most expensive of the lot and GP offroad being the lowest....ok guys don't flame me......just my opinion K.
EP response is very quick and very sensitive to changes you've made to your car settings and could fine tune to suit your driving style and track. Throttle response is instantaneous. GP on the other hand is a bit slow 'cos there are more mechanical movements......some lag time, compensate by using faster servos..... but you'll get use to it.
So....... are you an onroad who prefer their things clean and spotless or an offroad guy who just love to play in the dirt. The next question is are you an electrician or one who prefers a nitro methanol burning machines ?
Having said all that........the main thing here is to have FUN. be it EP or GP. Be it onroad or offroad.
Cheers man.
