Submarines go up and down in the water by changing its weight by displacing water...but how do humans go deeper or come up to the surface? We propel ourselves in the down or up direction using our hands and legs.....in this video we make use of a similar technique of using a propellor to dive deeper or float to the top and have made probably the worlds quickest DIY RC submarine.
Without the lights then one can actually make this under 5-10 mins

If you have a tendency to get motion sickness, then this compilation of drone crashes may not be the thing for you. But if you have a soft spot for hilarious fails captured on GoPro, then please enjoy.
The video includes drones crashing into chimneys, getting intercepted by a dog, making a not-so-soft water "landing," losing a propeller, and more debacles.
The video is set to the tune of "Another One Bites the Dust," but if Queen isn't your wheelhouse (because you're a monster) you can totally just imagine this is an update of the "Scrape" video by Unsane, replacing skateboarding biffs with quadcopter mishaps.
This is the maiden flight of what is probably the largest jet-powered scale model of a Mig 25. At 4.2 meters long and weighing in at 42Kg, this is a huge model, skillfully test-flown by 18-year-old Clinton on the first day of the 2011 ANZAC jet rally in Tokoroa New Zealand.
Great demo by world champion rc helicopter pilot Radio-controlled helicopters (also RC helicopters) are model aircraft which are distinct from RC airplanes because of the differences in construction, aerodynamics, and flight training. Several basic designs of RC helicopters exist, of which some (such as those with collective pitch control) are more maneuverable than others. The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities.
Flight controls allow pilots to control the collective (or throttle, on fixed pitch helicopters), the cyclic controls (pitch and roll), and the tail rotor (yaw). Controlling these in unison enables the helicopter to perform the same maneuvers as full-sized helicopters, such as hovering and backwards flight, and many that full-sized helicopters cannot, such as inverted flight (where collective pitch control provides negative blade pitch to hold heli up inverted, and pitch/yaw controls must be reversed by pilot). The various helicopter controls are effected by means of small servo motors, commonly known as servos. A piezoelectric gyroscope sensor is typically used on the tail rotor (yaw) control to counter wind- and torque-reaction-induced tail movement. Most newer helicopters have gyro-stabilization on the other 2 axes of rotation (pitch and roll) as well. Such 3-axis gyro is typically called a flybarless controller, so-called because it eliminates the need for a flybar. The engines typically used to be methanol-powered two-stroke motors, but electric brushless motors combined with a high-performance lithium polymer battery (LiPo) are now more common and provide improved efficiency, performance and lifespan compared to brushed motors, while decreasing prices bring them within reach of hobbyists. Gasoline and jet turbine engines are also used. Just like full sized helicopters, model helicopter rotors turn at high speeds and can cause severe injuries. Several deaths have occurred as recently as 2013.
Types of R/C helicopter
Common power sources of R/C helicopters are glow fuel (also called nitro fuel, nitromethane-methanol), electric batteries, gasoline (petrol) and turbine engines. For the first 40 years, glow fuel helicopters were the most common type produced. However, in the last 10 years, electric powered helicopters have matured to a point where power and flight times have equaled glow fuel helicopters. There have been two main types of systems to control the main rotors, mechanical mixing and cyclic/collective pitch mixing (CCPM). Most earlier helicopters used mechanical mixing. Today, nearly all R/C helicopter use CCPM. Practical electric helicopters are a recent development but have rapidly developed and become more common, overtaking glow fuel helicopters in common use. Turbine helicopters are also increasing in popularity, although the high cost puts them out of reach of most people.
Electric Two small electric helicopters emerged in the mid-1990s. These were the Kalt Whisper and the Kyosho EP Concept, flying on 7–8 × 1.2 Ah NiCad batteries with brushed motors. However, the 540-sized brushed-motors were on the limit of current draw, often 20–25 amps on the more powerful motors, hence brush and commutator problems were common. Recent advancements in battery technology are making electric flying more feasible in terms of flying time. Lithium polymer (LiPo) batteries are able to provide the high current required for high performance aerobatics while still remaining very light. Typical flight times are 4–12 minutes depending on the flying style and battery capacity.
In the past electric helicopters were used mainly indoors due to the small size and lack of fumes. Larger electric helicopters suitable for outdoor flight and advanced aerobatics have become a reality over the last few years and have become very popular. Their quietness has made them very popular for flying sites close to residential areas and in places such as Germany where there are strict noise restrictions. Nitro helicopters have also been converted to electric power by commercial and homemade kits.
The smallest remote-controlled production model helicopter made (Guinness World Records 2006) is the Picooz Extreme MX-1 sold at many toy stores (although this is infrared controlled, not radio), electronics stores and internet stores, costing about $30 (£28). The next smallest is the standard Picooz helicopter. Several models are in contention for the title of the smallest non-production remote-controlled helicopter, including the Pixelito family of micro helicopters, the Proxflyer family, and the Micro flying robot.
Glow fuel (nitro fuel)[edit] Glow fuel, or nitro fuel helicopters (not to be confused with gas, or gasoline powered helicopters) have been made in several sizes over the years. These are referred to as the "class" of the helicopter. They include 1/2A class, 15 class, 30 class, 50 class, 60 class and 90 class.
Check out our RC Boat carnage compilation. It is my Top 10 RC Boat Crash Compilation video. From mild boat flips and sinkings to violent and downright scary high speed crashes.
Some of these RC boat crashes show just how much momentum a high speed RC boat is carrying and just how easily they can sink without a trace.....RC boat crashes were never like this when I was growing up!
These are Losi 1/5th scale 4x4 Short Course rc trucks. Each one of them are powered by a gasoline/oil mix engine with an electronic brain. Each one of these vehicles have been modified in one form or another to optimize their performance, to the liking of their drivers.
Welcome to the RCSparks Studio Race Track, a private place we invite friends and family to have some awesome RC fun! The "Little Dirty" is a series of races prior to the BiG DiRTY Race held at the End of August (usually). These races are really just practice for the drivers and a chance to test out their rigs after modding, or purchasing equipment/new trucks. Today was Really Hot - about +35c and the engines are running well. We are all dying of heatstroke (Canucks are usually in a deep freeze), but loving every minute of it!! The racers came out and the volunteers were there to help out flipping some trucks! Really AWESOME!
I used 6 cameras to capture footage including 2 GoPro's, 3 Video Cameras, and a DJi Phantom for Aerial footage. Shooting this film took a lot of planning and preparation at the race track, as well as getting all the gear in the right place at the right time. A SPECiAL Thanks to Donna and Jennett, my two amazing Camera Ladies, as well as my bro Everett for assisting in getting great footage for all to enjoy!
An even BiGGER SHOUT OUT to all that help make RC ADVENTURES and these types of events possible! The Viewers and Participants are the reason we do this show.. and we certainly hope it keeps you entertained and inspired, for years to come!
RC Сars can drive through mud, puddles and stones. If there`s no mud, off road trail track is built of stones, sand and wood. These small-sized off road cars can drive in a deep mud and puddle with no difficulty. At the same time, RC cars look like real off road 4x4 cars and 6x6 trucks such as Toyota Tundra, Hummer H2, Dodge RAM, MAN KAT 6x6, Land Rover DEFENDER that are very strong and powerful. Sometimes it`s difficult to understand if it`s an RC car or the real truck. The main manufacturers of these models are RC Axial, Tamiya, RC4WD, HPI. I suggest to watch this video as RC cars drive through mud and off road.
People call these models of RC trucks as toys for adults because they are quite expensive. The set of RC truck with the car, the battery, electronics and a charger costs about $500.
Summit heads west to Las Vegas where the action is always hot. Except this adventure ditches the blacktop and leaves The Strip behind for some four-wheel fun out in the desert. Traxxas Summit puts its shiftable high/low transmission to good use as it runs across salt flats and rocky trails. When the trails get a little tougher and steeper, Summit uses its remote locking differentials to get its Titan 775 torque down to the ground. The Revo suspension and GTR shocks easily soak up the terrain as the massive 7-inch tall Canyon A/T tires grab traction. Summit is also equipped with waterproof electronics for when you encounter wet conditions wherever the adventure takes you. And when the sun goes down the fun keeps rolling. Summit is equipped with ultra-bright LED lights so you can see the trail ahead. Day or night, whatever the terrain, Summit is the ultimate adventure machine!
