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.

Zero Service after purchase They are all over you when they smell a sale, but when there is a problem, nobody helps you. They are just resellers of products, and their English is atrocious. Truthfully, bad reviews are deleted. I'm still waiting for parts from over a year ago. Stay away from this place. Go to Sterlingkit, Unlike these people, they actually answer your emails and concerns. Here, you only lose money!

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.

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:-)

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.
