ARR and RTR models come already assembled. The difference is usually that ARR model doesn't have a radio system installed, while an RTR model does. So don't be fooled by difference in price. When you buy an ARR car, you're going to have to add cost of radio system to your final cost.

The expense of operating your radio control car can be as little as an occasional replacement battery pack. But as with any hobby, more you play more you pay. If you become a dedicated radio control vehicle fan, be prepared for repairs, upgrades, special tools, magazine subscriptions, books, racing entry fees, association dues, travel expenses to big meets and races - list can be endless. The best advice is to start small, and let your radio control hobby grow little by little to whatever level you find most satisfying.

So all in all, what's best advice for getting started in radio control? Start small, get to know experienced radio control drivers, and learn as you go. Make a list before you buy anything, and make sure have all accessories and parts you're going to need to use your vehicle. Most of all, have fun - RC is a wonderful way to meet people, to challenge yourself, and to fulfill your driving fantasies.

1) Who has signed autograph? The key words here are "demand" and "scarcity." If a particular person's autograph is in high demand and it happens to be a scarce autograph, then you can expect it to have good value. This is why an autograph of Marilyn Monroe sells for over several thousands of dollars. She remains popular and her signature is in great demand. Her autographs are scarce when compared to those of entertainers George Burns, Jimmy Stewart or Joan Crawford, all of whom were around many decades longer to sign autographs for fans.

2) What item has been signed? A simple signature on an album page, menu, airline ticket or piece of paper is normally worth less than a signed document, signed photo, typed or handwritten letter. This is because it is most common type of autograph. All things being equal, a handwritten signed letter demands a premium since not only does it have a name signed at end but may also reveal something interesting, historical, or personal about writer. Thus, you're getting more than just a name signed on paper.

3) Is signature in ink, pencil or otherwise? Ink is worth more than pencil. Pencil can fade over time and usually isn't as dark and bold as a nice ink signature. Many collectors prefer and will pay more for ink signatures. But don't take this to mean pencil signatures don't have value. The great Apache Indian chief Geronimo signed pencil autographs at 1904 World's Fair in St. Louis. Today those pencil signatures on small cards can sell for at least $5,000. Today, most collectors prefer that photos and non-flat items be signed in sharpie or paint pen.

4) What is condition of autograph? Any damage to autograph, photo or paper will lower value. Smears, stains, creases, smudges, fading, tears, holes or other damage will always drop value of an autograph. To get top dollar and maximum value autographs must be in excellent condition.

There are several other small variables that can come into play when attempting to place a value on an autograph, but these four important questions are regarded as most basic factors that determine an autograph's value.

These are just a few of questions we receive from autograph collectors. If you have a question, feel free to contact us.
