For all of you nitro rc engine experts?

What kind of fuel should i use for everyday use
like wat kind of percentage of nitro methane or watever
ok i have a .18 engine engine, so the lowest can be 10%, what should be the highest?

It depends on if you are running a small block or big block.
Small blocks are up to a .18
Big blocks are .21 and beyond.

For everyday bashing with a small block you can use as low as 10% nitro. Big blocks, I would not go below 20% on.

I usually run 20% nitro in my small blocks for bashing. I have ran numerous brands from Traxxas, O'Donnell, Trinity, Blue Thunder, Byron Race Fuel ect and from 10% to 33%. I like to run 30% Byron Race Fuel in my truck when I race outlaw class.

Just buy a quart of 10% and run it, then step up to 20% nitro and re tune the engine and see what a difference 10% nitro makes. Some might say that switching nitro % from 10 to 20 or ever 10 to 30 will damage your engine. I have a RC10GT with a O.S. 15-CV that I bash with and I change the nitro % all the time in it. I have over 8 gallons of fuel ran through it and I've never had a problem with the engine. No rebuild, no signs of letting go. So changing nitro % is not a problem, if you do just reset the needles to factory settings and tune for performance.

edit.

The highest is what ever you feel like running. You can run 10% on through 33%. Good luck and happy bashing

im building an rc car and cant decide wich of these engines to pick?

im building a custom rc truggy from the ground up and i cant dicide between an HPI nitro star K5.9 or an HPI nitro star K4.6 HO. there both the same price and the 5.9 dosent show specs so i was wondering wich is a faster for a truggy

The 4.6 engine is better for truggies. That's the engine HPI are using in the new Trophy Truggy.

What are the differences between flight characteristics of a real airplane versus an RC airplane?

I am a pilot and may be interested in RC flying. I think most RCs use rudder to turn, whereas a real airplane uses ailerons. Real airplanes use power to control altitude and pitch for airspeed, but I don't know about RCs. Any thoughts for me? Also, what's a good starter plane?

Thanks!
I'm not confused. If you're going to tell me I'm wrong (which I'm not), at least tell me what's right! And you didn't even answer my question

it depends from the Channels of the RC station.

model sailplanes can work fine with one channel, controlling the rudder only.

two channels are usually rudder and elevator
then comes the throttle, and optionaly ailerons and sometimes other stuff, like remote cameras etc.
depends on how much weight your plane is able to carry.

under certain circumstances you could actually build a plane that would be two channel AND rudder and throttle, however you have to build it so that the propeller creates tail heavy momentum when working - that is, power up means climb, power idle means gliding down.
i cannot think of ANY safe mounting of the prop and engine that could ensure this ,and that mounting the engine and prop facing slightly upwards from the nose of the plane, whic is not practical

Does Aluminum absorb Radio waves?

i need to know if Aluminum absorbs radio waves (just the type that control an RC jet)

Aluminum is a good conductor of electricity. If an object is completely encased in a conductor (forming a Faraday cage), the object will be shielded from radio waves.

If the aluminum (or another conductor) covers only part of the object, radio waves may still reach it.

How do you connect a solar panel to a motor from an RC car?

Can anyone tell me how to connect a solar panel from a calculator to a motor from an RC car.

Connecting them is not a problem: the solar cell has two leads or terminals, and so does the motor. The problem is that the panel from the calculator cannot supply very much current, and you need quite a bit for the motor. Also, the voltage is probably not more than 3 volts, and the motor needs probably six to twelve volts. If you have a voltmeter, check the output from the solar cell. You can get solar cells that will put out more current, but they will be bigger than the ones used for calculators. Even with these, you will probably need several in series to get enough voltage for the motor.
