If you’re new to the radio control toys past-time, you’ll want to know some information about functionality, range, size, and power basics before you make a decision on the model that’s’s right for you. Some of these basics are merely “nice-to-know,” while some are comprehensive “need-to-know.” Some of this info represents “direct impact” information toward your final call of the exact model, manufacturer, scale, and motor type that best suits your present situation.
Your primary choices rely on if you’re purchasing the radio control model for yourself, your kid, your grandchild, or if it’s’s a present for a pal. This article presumes you have already made that selection, as well as whether you have selected a car, ship, van, aeroplane, helicopter, or construction gear – and you understand what level of expertise your selected RC vehicle requires.
Function makes reference to what type of control you have over the model. Your selections for function are : Single-function ( goes straight when moving forward, and turns left while traveling in reverse ). Full-function models go forward, backward, turn right and left, stop, and, in the case of construction equipment, lift, dump, load, and perform most of the functions of real life construction machines.
Designed mostly for small children, multi-function cars move forward, in reverse, steer one direction only and stop. Range is how far from the transmitter the model can go before it no longer replies to the control signal. This distance varies for the different remote control toys, but most toys fall into the range of 30-feet to a touch more than 180-feet. These interferences include things such as puny batteries, other nearby toys operating on the same frequency, citizen’s band ( CB ) radios, cell telephones, and nearby high-voltage transformers. Find the range stated on the package, and in the product description.
Scale tells you the size of the radio control, or chassis length, in relation to the real deal. The smaller the fraction, the smaller the automobile, and sizes range from the littlest at 0.33 2-scale to the largest at 1 / 8-scale. Those are NITRO ( internal combustion ) and battery. NITRO needs the extra purchase of liquid fuel.
Larger electric cars use chargeable battery packs in one of four different Ni-Cad voltage versions. They’re : 4.8-volt in a blue package, 6.0-volt in black packaging, 9.6-volt packaged in red, and the yellow package containing 7.2-volts of power. The 4.8-volt rechargeable battery packs usually are included with the model. Check the product outline to see. 7.2v models routinely don’t include the battery pack or the charger. Buy that separately. The transmitter control also needs either a 9-volt battery or multiple AA batteries. Occasionally the manufacturer includes those, infrequently not.
The product outline, and / or the packaging should tell you if you must make that an extra purchase. You now have enough info to lead you to the final call as to which radio control vehicle fits your needs and wants. Make your selection scrupulously and you, or your giftee, will enjoy many hours of fun with your RC model.

Radio control toys are a speciality that is easy to get into but has various aspects where you will require assistance.
the bigger the mhz number the longer the battery lasts and the more power you will get
no, magnets are not damaged by radio signals or by electronic components.
but your next sentence asks something different.
"Will the magnets or the "hover car's" electric engine be damaged by being in close contact (with the other magnets) ?"
it's an electric motor. but probably not. while a weak permanent magnet can be modified by a stronger one, it appears that the distances are too big for this to happen here.

It isn't that simple and first you must be able to get the exact replacement part. If it is a name-brand, you may be able to. Try Pacific Coast Parts in California as they are the official parts outlet for most major brands.
There may be some soldering involved. You may get lucky and have a plug.
1. A toggle switch on the Tx will move a servo on the appropriate Rx channel from one end of its travel to the other. Useful for undercarriage.
2. This is exactly what the motor controller does. If you want a DC voltage related to the Tx controller position, put a brushed motor controller in the appropriate channel. The top voltage will be the voltage of the battery you are using, which can be considerably more than the fraction used to supply the receiver.
3. See 2. The motor controller receives the voltage supply from the battery, and supplies the receiver through the cable to the receiver channel.
4. Servos will actuate movements in the robot. If you are looking for feedback from sensors in the robot you are entering a whole new region of electronics, since most enthusiasts solve this by programming microcontrollers.
One final note: some aircraft RC frequencies are not licensed for ground or water vehicles, including robots. Check your local regulations.
Lithium would be my first choice. If Lithium is not available then I would see if I could get Nickel-Metal Hydride (NiMH) though not as good as Lithium it is better than Nickel-Cadmium (NiCd). With Lithium you get full power until the battery is depleted, You are also able to charge them at any point and leave them on the charger. NiCd has a memory so you have to deplete the charge all the way (or really low) before charging or it will shorten the usage because it will think your last charge point is the depleted point. As for the RC longevity logically I would think the plain would use less battery because of it's gliding. Though I have no personal knowledge of this. Sorry.
Safe? Yes.
Recommended? No. Here's why:
The 2700 and 2500 mAh batteries are so close, you'll never notice any difference unless you apply scientific testing methods to measure it. But the 1300 mAh batteries will wear out in roughly half the time. Once they're down, the others won't matter. Think of it like a team of horses pulling a load. It's not going much of anyplace if two of the horses are tired out and lying down.
Also, older batteries tend to wear down faster than newer ones, so you want to avoid mixing those, either. Still, there is nothing unsafe about doing so. Most importantly, try to keep your mAh ratings within 10% – 15% of each other to get the longest usage before having to recharge.
Have you looked at casein? Alternately there is a latex based powder that you mix with water- pour into mold and it sets in about a day – used for sealing and levelling floors before tiling but I've seen it used to make non-standard size shower trays. It's a bit heavy and I'm not sure that the mechanical properties will be what you want. Other than that : resin and fibre glass mat?
