As others have posted pics of their RC toys, I thought I'd do the same:
This is my baby boat


and this is his mommy



This is their playmate

You have full control including diving, but doesn't work too well in a pond



and a little vid
hereThis is one for manna


And this is one for Jynx


This has all the extras including working headlights and spotlights, indicators that work as it turns, brake lights, reversing lights and beeper. Oh and a three speed gearbox.

This is my off-roader. It's actually only two wheel drive, but it's a lot of fun


And this is my Tiger with full option


It has very realistic sound -
watch this vid of it starting and switching offand full movement including turret turn, raise and fire.
Heres a videoThe black thing in the turret in this pic:

is the Tamiya "Battle system". A friend has one of these too and with the battle system we can have fights. Taken from the Tamiya website:
Taking a Hit:
You have just been hit by the enemy tank! You will hear the booming "damage blast" sound and feel your tank shake with the "blast reaction" effect. The GFS Unit will also flash to indicate the hit, and the sound and speed of your engine will slow. Also, directly after taking a hit, your tank gets "shaken up" and temporarily loses the ability to fire-you're down...but not out.
Blown Away!
Your tank can only absorb so much punishment. After a certain number of blasts (this too can be adjusted), you will hear an "explosion" and the GFS Unit will flash intensely. Your tank will make two final lurches forward before the engine shuts down and all tank control is lost. NOW you're out...but...
Back from the Dead:
The good news is that after a short period of "down-time" (about 15sec), your tank will come back to life with the "battery engine start-up" sound. For a short time, your tank remains invulnerable to enemy fire, allowing for some evasive maneuvering before striking back at your foe.
It's a lot of fun

Cheers
Nick
