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.

Recently received my ENJOMOR V12… Recently received my ENJOMOR V12 Engine GS-V12 from ENGINEDIY and as usual the service and communication was excellent. I bought the V12 on pre order, something I would not normally do due to the sum of money, but had no hesitating based on the service I received on my ENJOMOR V8 last year. I can say the company is a great company to deal with and if you are looking to buy any model engine, accessory or more expensive engines such as I have bought ENGINEDIY should be your first and only place to consider. Also the V12 is high quality and I am delighted and have left a separate initial review. Thank you again Lucas and your company ENGINEDIY.

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!

They don’t respond to emails regarding… They don’t respond to emails regarding their product once they have your money. I purchased 2 engines from them and they both don’t work. Don’t waste your money here
