Retrol HM-01 Hit & Miss engine. In 2023 I pre-ordered a Retrol HM-01 hit and miss engine from Enginediy which I knew would take a couple of months for delivery because it was still in pre production. I was happy to wait and I was kept informed of progress and expected delivery. It duly arrived very well packed and beautifully made. This was my first attempt at building an engine but it went together perfectly. The instructions were mainly pictorial and a little more written description would have helped but all my questions were promptly answered by their excellent service department. I have been running this engine for four months now and I’m delighted with the design and quality. I would certainly recommend Enginediy and will be using them again.

Great product-excellent fit and finish - superb service I was pleasantly surprised by the excellent fit and finish on this mini drill press. Very well made product. Was looking for a small tool to do some very tiny work on the deck of the boats I make and yet take up little space on the workbench. And this does it well. Well worth the price and love EngineDIY free shipping and fairly fast delivery to Canada - hassle free for sure. Had an issue with the power supply not included but the Customer Service came through and solved my problems immediately - Good Job!

No customer service & they delete negative reviews I've made several orders from them and always got what I ordered. One expensive item (<$1K) arrived with some inexpensive parts missing. I provided them with the prod #, missing parts#, part description, & photos from their assembly manual. Many emails were exchanged. Still, the service tech was unable to correctly identify the part. He guessed at it and twice sent me the wrong parts and then gave up. When I wrote a negative review, they pulled it off their site.

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.
