What are push-pull tubes in aviation?
Certain aircraft designs utilize a system of push-pull tubes for their primary flight controls. These tubes are usually fabricated out of an aluminum alloy tubing with threaded rod ends riveted into the tubing. Bell cranks are then used to change the direction of travel of the controls. Push pull rods are extensively used along with bell cranks to.A pushrod is used to transfer motion from one device to another. In a radio control airplane, a pushrod is used to transfer motion from a servo to a control surface, throttle, retractable landing gear or anything else that needs to be moved.
How to pull a boat tube?
Get the boat up to speed, swing the tube out to one side then sharply turn the boat to swing the tube all the way out next to the boat on the other side. Once the tube is passing across the back of the boat bring the throttle down. The motors used to power tubes need to be able to provide about one horsepower for every 40 pounds of weight. The boat should be able to reach a speed of about 20mph in order to tow a tube. If you plan on towing more than one tube, you should consider a pontoon boat with a higher horsepower.Your 40 hp motor should be plenty to get them to towing speed, which is slow (10 mph/15kph-ish). There is a LOT of pressure on the tow rope, though, so unless that handle is bolted through the transom, I would look for something stronger.The motors used to power tubes need to be able to provide about one horsepower for every 40 pounds of weight. The boat should be able to reach a speed of about 20mph in order to tow a tube. If you plan on towing more than one tube, you should consider a pontoon boat with a higher horsepower.For example, if your pontoon is a 22-foot boat with a 150hp motor, there are two people in the boat, and you are pulling a few kids on the tube, their ride will be fast and thrilling. But if your pontoon is 16 feet long and has a 115 hp motor and it’s loaded with passengers, the tube ride will be slow and leisurely.
What are towable tubes made of?
Constructed with durable, heavy-duty nylon covers and thick gauge PVC bladders, they will last and provide fun for many seasons.

Wakeboard towers, pylons, and other ski tow bars have a manufacturer’s warning stating it is not safe to tow tubes or other inflatables – doing so could damage your boat and potentially hurt passengers!Pull Tubes from Nearly Any Boat by Adding a TurboSwing Turboswing is designed to work cooperatively with virtually any outboard motor, whether you’re planning to pull from a runabout, pontoon boat, fishing boat, cruiser, or other boat style.Only attach the tube tow rope to a point on the boat designed for that purpose. You may attach the tube tow rope at the transom “ski eye” or transom U-bolt tow point or a tow pylon on the transom. Never attach the rope to a cleat or to the engine. Also, never tow a tube from a wakeboarding or sport tower.
Are towable tubes safe?
Only tow a tube if the boat has a qualified driver and capable observer. Tow in control; ‘getting air’ is fine, but overdoing it, especially on multi-person models, can slam riders’ bodies into each other or objects and cause severe injuries. Overall, you can safely pull multiple tubes with the TurboSwing but other towing solutions may not be safe for this activity. You should always use caution when pulling multiple riders and be aware of your riders and your environment in order to ensure a safe day on the water!
