hi guys was just wandering i am new to RC flying i have a chopper my self and was wandering on the transmitter it has its “chip” of 35 MHz what does this have to do with it? the distance before it loses signal or something else?

3 Channel mini RC Helicopter with metal airframe.
The best 3 channel mini rc helicopter for only £18.99 including postage! this heli has a bigger battery and a metal airframe even with bearings on the rotor shaft. the detail is brilliant and it also flies very well. i have had many mini rc heli’s and this one is the best by far. it comes with spare blades and a screwdriver. i would recommend using rechargeable batteries as the heli charges from the transmitter and eats batteries as you will be addicted to this heli. it is very stable and easy to control with left, right, forwards and backwards control. The heli comes in three colours, red, green and yellow. i am still amazed at the price for this heli as it is very well built, does not look cheap and flies brilliantly. a 25 minute charge gives roughly 5-9 minutes of flight time. Enjoy and please leave a comment.

I need to get a cheap Radar Gun to measure the speed of my RC Boat Where can i get a cheap one to in Australia?
I need a cheap Radar Gun that measures a long distance between yourself and the boat. where can i purchase one? i have looked all over the net and seen many for $800 to $1000 which is too much considering what i need it for. i also seen the Hot Wheels radar gun but it only measures a short distance.. Im running a 1/8th Hydroplane Rc Boat. i have just rebuilt it , after it caught a pocket of air on the last run and flew a few meters in the air before coming down ripping it apart in some areas. now i want to know what speed i was travelling at for it to cause the damge. if anyone can help be great!
Cheers!

A quarterback takes the ball from the line of scrimmage and runs backward for 10 m. He then runs sideways, parallel to the line of scrimmage for 15 m. Next, he throws the ball forward 50 m, perpendicular to the line of scrimmage. The receiver is tackled immediately. How far is the football displaced from its original position?
43 m
225 m
1,600 m
1,825 m
A duck waddles 2.5 m east and 6.0 m north. What are the magnitude and direction of the duck’s displacement with respect to its original position?
6.0 m at 50° north of east
42.25 m at 67° north of east
6.5 m at 23° north of east
6.5 m at 67° north of east
A fox sees a piece of carrion being thrown from a hawk’s nest and rushes to snatch it. The nest is 14.0 m high, and the carrion is thrown with a horizontal velocity of 1.5 m/s. The fox is 7.0 m from the base of the tree. What is the magnitude of the fox’s average velocity if it grabs the carrion in its mouth just as it touches the ground?

A boat moves at 10.00 m/s relative to the water. If the boat is in a river where the current is 2.00 m/s, how long does it take the boat to make a complete round trip of 1,000.0 m upstream followed by 1,000.0 m downstream?
83 s
125 s
200 s
208 s
A person is strolling along a moving walkway at a constant velocity of +1.00 m/s with respect to the walkway, which moves at a constant velocity of +0.50 m/s with respect to the ground.

Can an electric igniter from a grill light a firework fuse?
I have a panel for launching fireworks from a distance. It uses model rocket igniters to set off the fuses. The local hobby store doesn’t sell them anymore, so I was thinking of using the electric igniter from a grill to light the fuses instead.

Help in Algebra 2 Honors please. Two questions posted below. Please post answers soon?
1.) In an engineering test, a rocket sled is propelled into a target. The sled’s distance d in meters from the target is given by the formula d = -1.5t^2 + 120 where t is the number of seconds after rocket ignition. How many seconds have passed since rocket ignition when the sled is 10 meters from the target?
2.) The height h(t) in feet of an object t seconds after it is propelled straight up from the ground with an initial velocity of 60 feet per second is modeled by the equation h(t) = -16t^2 + 60t. At what times will the object be at a height of 56 feet?

jenny’s model train is set up on a circular track .?
there are six telephone poles evenly spaced around the track .it takes the engine of her train 10 seconds to go from the first pole to the third pole .how long would it take for the engine to go the entire distance ?
the answer is not 20 second !
draw a diagram to help you determine the correct answer .
