IS it possible to have a genorator for a nitro car? Also anyone know
of any good head lights and taillights they recommend?

[sanj.varah]

yes in the form of an alternator, the problem is you'd need some sort of
sink (battery) to receive the charge, otherwise as the engine RPM increased
the regularity of the power supply would fluctuate.

you should also note that you'd have reduce power output at the wheels
because some of the power goes to the alternator.

as far as headlights and tailights go, i would recommend you go for LED's
they are lightweight and consume naff all power.

Generaly people run their LED's off of a 9 volt block battery. If you went
the alternator route, though, you could sink the electricity into capacitors
with the help of an electronics buff, which would be more efficient (and
maybe lighter) than batteries. If you're going to have batteries on there
anyway, why use the alternator?

DO you know were could get one?

[sanj.varah]

with the use of an alternator you could have a much more powerful headlight.
In my road car I use 55/100W bulbs which may cough... cough.. transgress EU
regulations but are nonetheless very bright, you could do the same on your
nitro, but dunno why you'd want one.

[sanj.varah]

yeah a bicycle dynamo would be your best bet.

The current is self regulating (but not quite perfect) in this sort of
system.

It has been used extensively in garden tractors, snowmobiles, dirt
bikes, gokarts, and other places (probably).

The reason the current is self regulating is that the frequency of the
AC in the stator is proportional to voltage (&RPM). The major
impeadance is the inductance of the stator windings so the higher the
RPM the higher the voltage and frequency (impeadance).

An airplane version is listed by towerhobbies:

LXFV20 Sullivan Genesys In-Flight Power System $99.99

And I thought it was made by 'top flight'.

It is possible but I haven't seen any alternators that would fit. You
wouldn't neccessarily need it to feed a battery but would need filter caps
and a voltage regulator depending on what your powering. You can get white
and red LED's for head and tail lights. Usually you scratch the paint out of
the light window of the chassis and glue them on (or cut a whole right
through the chassis).

I have seen some RC cars done up to look like police cars with little
flashing lights and sirens but I have never seen one with an alternator.
Your better of just using a 9V battery. LED's only need a few mA so a 9V
battery will last as long a 1L of fuel will.

I am going to build one some time. I am going to make a disc that has like
10 little magnets (out of an electronic toothbrush), which are really
strong, and attach the disc to one output shaft on my tranny. Then I will
mount a small, high wind coil on the chassis and attach the leads to a
capictor bank/diode bridge, then I will hook up LEDs with the proper
resistors. It will cost about $50 total and probably take about 2 or 3
days. I can't wait to do it, but I don't have the money right now, and I've
been playing with my little palm runners a lot lately (immitation min-z
racers).

Any electric motor with an inside magnet can be used as a generator,
the size of the motor is what makes the difference of the output
voltage and current, and the connection with a battery makes a cheap
and easy voltage regulator, it doesnt matter the current that the
generator produces with the RPM if is more than the one you are going
to use nothing happens, what you have to take care of is the max
voltage that the generator gives at high RPM, because if its very
different than the battery voltage, the battery can explode, the idea
of the leds is not bad, but you cannot compare the light that gives a
led with the light that gives a lamp bulb for example. The big problem
here is how to connect the generator the the car engine, this is the
only thing than i think is difficult.
