Features:


.Introduction: The L4-172 is a miniature inline four-cylinder four-stroke engine model newly released by the HOWIN team, which demonstrates a strong engine manufacturing spirit. It is based on early real car engines that are widely used and designed with perfect style and appearance, recreating the elegance of full-size cars in scale models. Delivers a sense of realism from inline four cylinders to camshafts and rocker arms, every effort has been made even the scale&appearance of the engine to maintain a high-level performance that can provide extraordinary power to RC cars/ship models.
.Mainly decorated in silver and black for a high-end atmosphere, the L4 engine with an overall compact structure represents a collision of retro classics and modern machinery.
.Adopts SOHC valve mechanism, alloy rocker arms, independent intake/exhaust design and increasingly accurate valve opening/closing.
.Built with adjustable valve and single carburetor for easy adjustment and more sensitive throttle response.
.The intake pipe and exhaust pipe printed by integrated metal stainless steel make the engine sounds deep and powerful like a racing car.
.The integrated & reinforced crankshaft with five points to fully support ensures that the crankshaft boasts sufficient strength and is not easy to deform under high-speed operation.
.Utilizes the external centrifugal water pump and the cooling mode of direct contact between the outer wall of wet cylinder liner and coolant for heat dissipation with water drainage to prolong the working time and span life.
.Features smooth idle running and a high speed up to 15000rpm like a little violent beast, due to the 480 brush motor and convenient electrical starting.
.All parts of the model are made of carefully selected material, among which the piston ring is made of nodular cast iron, and the cylinder block & crankcase of the cylinder head are processed by aluminum alloy CNC,  as well as colored through anodic oxidation after sandblasting.
.To maintain the steady output of the inline four-cylinder engine, the rocker arms, camshaft and crankshaft are precision machined for minimal tolerances.
.With its true-to-life scale, reliable start and steady power, the high-performance engine will meet the expectations of many model aficionados, providing an impressive&authentic model for nostalgic enthusiasts and collectors.
.Instructions: 1. Includes 1 x Engine, 4 x Glow Plugs, 1 x Ignition, 4 x M4 Screws for Assembly & Fixed, 1 x Instructions, 1 x Optional Engine Base. You need to prepare or purchase the fuel tank, fuel lines, water cooling kits (radiator and water tank) and batteries.
2. Requirement for Fuel Oil: 20-25% Nitro Finished Fuel Oil. Later you can buy the gasoline modification kit to upgrade to use the gasoline fuel.
3. Warranty & Aftersales: One-year limited warranty. If you have any questions about the product in use, please feel free to contact us for advice or help.

A bit disappointed
Color: Pine Green
Needed a new cover for my Ipad 11. This product had a good price, options for colors (I picked the green) and shipping was fast. When it arrived out of the box I was disappointed. Putting my Ipad 11 into the case was a bit harder than I expected. Once in, either the top or the bottom would not sat seated in the case. The backlight is nice, but you have to charge the keypad and ipad separately. I returned this because you have to physically move the keyboard to either use it or close the case or get the Ipad to stand. So, when closed the keypad sits right under the Ipad screen. When you open the case and want the ipad to stand, you have to physically slide the keyboard towards you or down to the bottom of the case. This then allows you to fold the upper portion and stand the ipad upright. You have to reverse this to actually close the case. What all this means is two things for me...this setup takes more deskstop space and a few more movements to get everything setup.

Keyboard will rub its color off, onto the screen of ipad
Color: Dark Cherry, Color: Dark Cherry
Over all I love the color and idea of this case. Keyboard works great but the keyboard I have to cover it if I want to carry it in the case with my iPad it’s edges fit inside the case and will scratch and leave the color on my iPad screen I have been covering it with a paper towel when I want to keep in inside to take it with my iPad. I do love that the keyboard magnetic feature and can be moved. Two stars only for the inconvenience of having to find something to cover the keyboard

Fantastic keyboard!
Color: Navy Blue, Color: Navy Blue
Pleasantly surprised!! And less than half the price of an ipad folio keyboard - I know, one feels like one has to stay in brand. So I was nervous about buying a keyboard that wasn't made by Apple. But to be honest, the Apple keyboards and mice have betrayed me on numerous occasions. They have not earned my loyalty and need to reassess their dubious life choices. I needed a protective cover to stop my cats doom scrolling while I am asleep. I am OK with them using the internet - even though I have had random people text me back a picture of a large feline left nostril and just the letters WFT? It is what it is. I think they are little geniuses. But they scratch the ipad surface which is annoying. So I thought, what the heck - I am about to do my RN-BSN online and need a way to make my ipad transportable while protected, and set up so I can easily bang out some homework assignments on the run. Easy set up! What a relief! Tech usually hates me - sees me coming from a mile off and starts planning to at best ruin my day, and at worst have me calling my therapist. At first I started reading the instructions and my teeth hurt from the bad translation into English. But even with that negative energy I was able to set it up very quickly. Everything just WORKED!! I know. I set a low bar. These days one has to. This time I didn't need to. The cover is sturdy, soft and coffee resistant, thank goodness. The keyboard just plops on, connects through magic and immediately makes me feel like I am not as stupid as I thought! Absolutely recommend this wonderful keyboard - I dunno who do this voodoo but I am very excited. Crack on my lovelies! Make those dreams a reality.

Great product!
Color: Light Pink, Color: Light Pink
I really love this. The baby pink is so cute! I had my hesitations because I couldn’t see if the pink would be as good in real life. It’s like a soft blush color. Honestly, I was going to drop $350 on the Magic Keyboard for my iPad Air. Which is ridiculously expensive. This is a way better alternative. It fits my iPad pen. The iPad itself fits perfectly. I thought the keyboard was going to be tacky and cheap. But it’s pretty legit too. I love that when I’m done using the iPad, the whole case protects everything, even the keyboard inside and especially the camera lense. The magic key board does not have that feature. Like that it’s magnetic too. The material is so soft to touch. I can see how it can get dirty with ink spot if not careful. Overall, really happy with this purchase!
