Smallest RC model helicopter, radio controlled
The smallest remote-controlled model helicopter is the Nano Falcon by Silverlit Toys Manufactory Ltd. (China) which measures 8.11 cm (3.19 in) long, 5.09 cm (2.00 in) high, 2.24 cm (0.88 in) wide and has a rotor size of 6.98 cm (2.75 in). It was measured in Causeway Bay, Hong Kong, China, on 13 March 2013. The helicopter flew for 5 minutes 15 seconds during the test flight performed on 13 March 2013. It weighs 10.43 grams.
Smallest RC model aircraft, radio controlled
The smallest radio controlled model aircraft had a wingspan of 69 mm (2.72 in) and was created by John Wakefield (UK) in Lancaster, UK, on 27 October 2010. The aircraft, model BF5, flew for 6 min 56 sec and weighed just 1.98 g (0.07 oz).
Smallest radio-controlled car
The record for the smallest radio controlled car is a 25 mm long model (1/90 perfect scale) of a Mercedes Benz Smart car developed by Michihiro Hino, Tokyo, Japan in 2002. Specification: -RC equipment: 45MHz belt PSD system Toy-RC 2ch -Battery:Micro-nickel hydrogen rechargeable battery. -By continuation operation time: full charge,it is about 15 minutes.
Smallest tooth extracted
A primary tooth (tooth E) extracted under local anaesthesis from Colton Laub (USA) on 30 October 2002 by Dr. Scott Harden (USA) at Fountain View Family Dentistry, Acworth, Georgia, USA, measured 3mm (0.1 in) long. The average length of a microdont tooth is 13 mm (0.5 in).
Smallest toilet
The world’s smallest toilet, ‘Chisai Benjo’ in Japanese, was created by Takahashi Kaito of SII Nanotechnology Inc, Japan. Created by etching a silicon substrate with an ion beam, the development will no doubt be welcomed by future generations of nano-robots. A scanning electron micrograph of the creation won the Most Bizarre Award at the 49th International Conference on Electron, Ion and Photo Beam Technology and Nanofabrication Bizarre/Beautiful Micrograph Contest.
Smallest spy plane
The smallest spy plane in existence is the palm-sized Black Widow, developed by Aerovironment of Monrovia, California, USA, for possible reconnaissance use by ground combat troops. It has a wingspan of 15.24 cm. (6 in.), weighs just 80 g. (2.8 oz.) and carries a tiny color video camera weighing 2 g. (0.07 oz.). The Black Widow has a speed of 50 km./h. (30 m.p.h.), a maximum range of 2km. (1.24 miles) and can stay airborne for 30 min. Although it has an autopilot, it will Continue reading →
Smallest shark
Due to the difficulties in determining precisely when a small species is sexually mature (i.e. an adult and fully grown), there are two, possibly three, contenders for the smallest spieces of shark. The most likely record holder is the dwarf lantern shark (Etmopterus perryi), males of which measure a total length of 16-17.5 cm (6.3-6.8 in) (with one confirmed male adult specimen collected measuring 19 cm or 7.4 in long), and mature females of which are typcially 19-20 cm (7.4-7.8 in). Prior to the discovery Continue reading →
Smallest scale three dimensional map
The smallest scale three dimensional map is a representation of the 2df survey of galaxies in a glass cube. It has a scale of 1cm=1 billion light years (around one to one billion billion billion) and is produced by Crystal Nebulae (UK). All of the approximately 200,000 galaxies mapped in the 2df survey arel represented within the cube. The galaxies are etched inside the cube by a laser, with a positional accuracy of 40 microns. This corresponds to a spatial uncertainty less than the results Continue reading →
Smallest Rubik’s Cube
The smallest Rubik’s Cube is10 mm (0.39 in) wide and was created by Evgeniy Grigoriev (Russia). It is fully functional and can be used like a normal Rubik’s Cube. It is 2mm smaller than the previous one he made. http://thatstoday.com/article/2801165/evgeniy-grigoriev-creates-worlds-smallest-rubiks-cube
