Fantastic Fantastic! This is the 4th project I've purchased from EngineDIY and I have enjoyed each and everyone. The Rotary 5 Cylinder, the Fighter Jet Engine, the V8 Flat Plane Crankshaft Engine and now the Turbofan Jet Engine. This particular model project is made from all metal parts with precision fitment and provides 20+ hours of assembly enjoyment. All of these projects are in lighted displays in my home and are enjoyed by friends and family. Especially noteworthy is all these models "run" by rechargable battery. Watching pistons, gears, propellers and machine parts move is awesome! I've been purchasing from this outfit for 4 years and look forward to future kits.

my trusted agent the knowing that the investment in the item being shipped is in the best hands and care ,as if in your own hands.

44cc Small block Hottie V8 engine This is my second engine directly from CISON. My first was the V2 15.7cc Harley Davidson Engine and now the Chevy small block V8. Both, I am very pleased with because both came directly from the manufacturer in China and the price compared to buying them in the U.S. is much cheaper directly from China. Customer service is absolutely great! I hope you are lucky enough to speak with Lucas! You can usually get a response very quickly. My experience has been within 24 hours! I first contacted CISON about a Hall sensor that went bad on my V2 engine. I had the sensor in my hand about 10 days later straight from China. My second experience was for instructions to assemble the V8 in English. I was immediately sent assembly instructions in Chinese that Lucas said would be converted to English and sent to me later. I actually converted the instructions to English and sent them back to CISON before they could do it! I simply used adobe to convert the document to word format in Chinese and then converted Chinese to English! They were very appreciative to me beating them to the punch. I am still in the process of assembling the V8 and will post videos to YouTube immediately when finished. These model engines are a real work of art and very mind blowing! Today I demonstrated the Harley Davidson engine to automotive students at my school and they were totally blown away that it actually runs..... myself and the instructor showed the partially assembled V8 engine to the students and they can't believe something that small and realistic actually work and runs! They wanted to hold the block! The price you pay for these engines is small compared to the WoW!!! you get from future automotive technicians. My plans are to purchase another one and donate it to the school. These things are great conversation pieces, fun to work on and even great to just look at! I love my purchases from CISON because they're trustworthy, reliable and better to purchase from than local. Stay tuned for my first videos on YouTube that will demonstrate problems, fixes and downloadable instructions in English. My first video will show what's in the box? Assembly and then running! Stay tuned...... I'll be back!

Steam Beam engine. I was pleasantly surprised by the finish of all the parts. More so by tiny ball bearings. Need to read double check instructions. Classic RTFI. Else go back undo, do again according to picture. Very free running with careful assembly. As much a display piece as working model. Note flywheel already has grub screw installed. Model even turned over on blowing into boiler. This the beam engine. Very happy. Only just enough screws:-)

Great and Respectful Service I like EngineDIY because they always do what they say they will do. If you have any problems assembling one of their excellent kits, an email to enginediy.com will get you a quick reply. I recently purchased a very new model. Understandably, there have been a couple of production bugs, causing me to email EngineDIY to ask for replacement parts. They were sent to me without complaint as soon as they could source them. You are safe with EngineDIY. Recommended!
