Petrol R/C Car - Which to buy? (UK)?




ZAMtendo


What is the best, most value for money petrol R/C car to buy in the UK? I'd like to make it a hobby, what is a good place to begin, and which should be my first R/C car?

Thanks!



Answer
Well, if your starting out into the world of RC, i would strongly suggest you start electric. There are 4 types of engine that run RC cars. Electric, electric brushless, nitro, and petrol. Electric tend to be your cars that can do 20-30 mph, are good for throwing round jumps, take very little maintenance and aren't too expensive.
Brushless electric motors are a new technology, and therefore quite expensive. However, brushless electric has become a reall challenger for nitro in speed and power, though as with all things on batteries, you can only run them for a limited time. Brushless cars run from 35-70 mph, depending on your motor and setup.
Nitro is the most popular choice about. A small single cylinder engine running on a nitro/oil fuel mix. A starter nitro car will do about 40 mph. The thing with nitro cars however, is that they take alot of maintenance and love, and alot of time to get going when you first get them. If you do decide nitro, get your hobby shop to adjust all the needles, and run it in for you. But make sure you take the time to watch them do it, and read some how toos online.
Final petrol. Bigger two stroke engines, very like those in a petrol lawnmower. These cars are the biggest you can buy, run on actually petrol, and are a very limited class. I dont know alot of people who own them, and there isn't a class to race them at my track. (I personally wouldn't buy petrol). They need a whole lot of space, and similar maintenance to nitro.

Right, after that rant, ill give you a couple of examples.

Nice starter nitro cars; http://www.speedymodels.com/nitro-sport-33-p.asp
Traxxas is a good brand, and this car has been specifically designed for a begginer in mind.(It's offroad, will give about 40 mph, at top performance)

is one you can grab from your high street shop.

Please remeber with nitro that you need a glow start. (Which heats the glowplug etc,) As well as the car, and these tend to come seperately.

Some good stock electric: http://www.rccarsandtrucks.co.uk/1248_1_105820349.html
Is super cheap and cheerfull, will do about 15-20 mph. A great begginers rc car.

A friend owns one of these and loves it. You'l get a good 30 mph out of it, and its totally waterproof. See the you tube videos. A great buy imho.

http://www.nitrotek.co.uk/H94107.htm I own this one, and love it. My first RC car, virtually indestructable. Will do about 25 mph, maybe just 30 with a better battery.

If you do buy one of these, make sure you get the battery and charger thrown in, most high street shops will be willing to haggle.
I would really suggest considering a stock electric for your first RC.

Finally, electric brushless.
I own and like http://www.nitrotek.co.uk/A2012T.htm
40 mph plus, but takes alot of control. I trashed mine first time i took it out, as i really underestimated the acceleration.

http://www.rccarsandtrucks.co.uk/1962_1_1342158.html
Is a good car. Though you wont get the battery and charger thrown in, so you could end up with about £350 worth of bills.

If you want to try brushless on the cheap, i own; http://www.nitrotek.co.uk/A2003T.htm
It's like a tiny jack russel, about 35 mph, and fantastic fun.

Whatever you decide, always read the instructions, and always take it easy first time out. If you have any problems, model shops will help, and there are always many the forum for this sorta thing.

Have fun!

Can I use "bad petrol" from my lawnmower in my car?




East Ender


I had some petrol left for my lawnmower from last year. I filled the tank with fresh petrol (about 8 litre), obviously contaminating whole content of my tank. The lawnmower had difficulty in starting. When it started it ran OK but it started kicking back when I started the engine again. I suspect the trouble is with the oxidized petrol I have in the lawnmower and the tank. I do not want to waste this petrol. Can I use it in my car? Are car engines more tolerant than small petrol engines? May be the problem lies somewhere else and not in the "bad petrol". Perhaps someone out there knows?


Answer
What happens with old gas is that it loses its most volatile compounds in there and the rest will not burn well enough. There also is a tendency for "varnish" to form in that gas.

That means that if you use the stale gas in you car you can have starting and gumming-up problems there too. The cost of cleaning your car's fuel system is more than the value of the gas you are recycling.
