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.

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.

Enjoyable hobby I got the kit in the exact shipping time. I am really appriciated for that. As soon as i had free time after my ordinary works, i had focused on it in the evening. A happiness occured on my face at the end of the work . Because it was really enjoyable to create such nice hobbies. Thank you for all people who generated such nice works for us.

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.

Is this place legit I placed an order on 27 November 2023. My credit card was charged immediately. I did not receive an email informing me that the order had been received. I have no shipping date, tracking number or any information from enginediyshop.
