.Alpha dragon IV is a new generation of high specification pre-grinding 3p engine with new design and modification. It is fuel saving, easy to adjust, and has excellent performance. After a little debugging, it can be used.
.Features of New design parts as follow: the body has been redesigned to increase intake and exhaust efficiency and improve fuel flow from the carburetor to the combustion chamber, thereby reducing losses, increasing fuel efficiency and increasing engine power. Ceramic post - perlin: Reduced friction, lighter weight, extended service life. This ceramic post - perlin is a basic part of the dragon IV. Using high-quality materials can apply more kinetic energy to the wheels with less resistance, reducing the friction coefficient. Lighter weight reduces rotation resistance, increases engine power and acceleration, reduces fuel consumption, and makes the engine more fuel efficient. Dynamic balancing crankshaft: reduces engine vibration and has good lubricity. The new DEC crankshaft contains an Alpha patented counterweight balance that effectively balances power transmitted from engine ignition to piston pins. The inertia force of the connecting rod and crankshaft rotation reduces engine vibration and increases engine power. This dynamic balancing counterweight crankshaft, with a new cylinder piston, makes more power and more linear power for maximum output. The new cylinder piston's air intake has been redesigned to provide oil savings, more power and more linear power for maximum output. Piston pin: the piston pin is light in weight and enhances surface hardness and durability to reduce the possibility of piston pin bending. Radiating head: the new radiating head adds a layer of radiating fin, and is lowered to lower the center of gravity to make the car more stable, better handling, when loaded on the car, it can maintain good radiating effect
.Safety Instruction: The engine is not a toy! Please read the instruction manual to become familiar with the features of the product before operating. Keep yourself and those around you safe. To maintain the best engine performance and longer service life. Incorrect or faulty maintenance can result in damage to the product.

Keeps clutter away
Size: 7.7" x 7.7" x 1.7", Color: Black (Metal Silvered)
This works great to corral all my notes I write on post its or small notes. Keeping them hidden from the desk top b/c or the depth but still visible to me. Much better than keeping on the plotter. Looks great in quality .

Attractive, Simple, And Well-Made
Size: 7.7" x 7.7" x 1.7", Color: Orange (Metal Glided)
I use this as a "catchall". A place to stash things like my wallet and keys when I enter the door, so that I don't use them (I had been prone to that!). It serves it's purpose well. It's both sturdy and attractive, and a good size for a "catchall". Recommended for those like me who need such things.
