Duratrax Street Force GP2?

RC Car gas.It feels and sounds like it takes for ever to go fast and like its slipping.Its not that the clutch is too lose.Or that it needs to be tunned.Im not sure what it is.Imput would be appreciated.Thanks…

Why are we still using the antiquated system of income rather than a true fair tax on sales?

Income taxes punish the labor force for earning wages. A true fair tax is one striclty based on expendatures. Regardless of how you obtain your money, you are taxed at the time you spend it. Then, if your purchasing a big ticket item, you pay more tax than a less expensive model. This is not rocket science. Any red neck can see it is a better way to conduct business. Why can our educated leaders not?

does anyone know how to tune an ofna rc car 3.5 engine?

where to buy a nitro (ofna) .12 force head button?

it’s for an rc nitro car

is it possible to launch a model rocket from an rc helicopter?

I want to know if it would be possible to launch a meduim sized model rocket from a large R/C helicopter. i am talking about a vertical launch not shooting it horizontally like a gun. i was thinking that i would have to build some sort of launch platform but then i realized that the force of the rocket would throw the heli off balance. could i cut power to the heli and let it drop for a few seconds while the rocket launches? i really want to know if this will work for sure before i go out and trash the helicopter.
what is AMA? and why would it make this illegal?

please help! im so stressed with these 3 problems?

1. A worker pulls a sled with a force of 80 N directed at an angle of 60 degrees above the horizontal over a level distance of 6 m. If a frictional force of 24 N acts on the sled in a direction opposite to that of the worker, what net work is done on the sled?

a. 240 J, b. 216 J, c. 144 J, d. 96 J

2. A model rocket sits on the launch pad until its fuel is ignited, blasting the rocket upward. During the short time of blast-off, as the ignited fuel goes down, the rocket goes up because:

a. momentum is conserved in this process
b. the fuel pushes on the ground
c. air friction pushes on the escaping fuel
d. the downward force of gravity is less than the downward momentum of the fuel

please explain why you believe the answers are what they are just in case yours are different than mine. thanks a lot guys!
3. A 10 g bullet with an initial speed of 100 m/s is fired horizontally into a 90 g wodden block initially at rest on a frictionless horizontal surface. The bullet passes completely through the block and emerges with a final speed of 20 m/s in the horizontal direction. How much mechanical energy is lost in this process?

a. 44.4 J
b. 50 J
c. 26.4 J
d. 20 J

Physics problems, just want to double check my answers?
