Just go ahead and pull the trigger! The ordering process was easy, tracking info was timely, and engine was packed carefully. I incorrectly thought a component was missing and contacted customer service. They quickly responded with directions to find the part in my kit. i am so happy with Engine DIY tgat I bought ANOTHER product from them!

After 12 days, I recieve good protected package, with no damage, delivered direct to Switzerland. Perfect toy, no only for kids but also for engineers, like me :) , works perfect as described. Highly reccomended, I will definitely come back. Thanks :)

Pleasure to do buisnes… I have had the pleasure to do buisnes with ENGINEDIY several times, never had any problems, very nice products and great service.

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.

Toyan V800 base Toyan V800 base Built the base with the additional parts of 3 ea, motor starter modules to make switching loads for a start enable (whole unit power), glow plug power(power to the 2 plug units), and the motor starter (self explanatory). I also added a second start button switch for safety to help prevent a stuck starter button sw from burning up the starter motor. So functionally. You have to press both start switches to crank the motor. I soldered all connections and used heat shrink to insulate the connections. All the electrics are installed inside the base. I did relocate the mounting of the motor to my preference. I’m still waiting on a replacement black fuel tank, or the glass for one end of my tank as it came with a cracked glass on one end.
