Total satisfaction. Have been in contact with the guys at enginediy regarding a shipment from them. The model engine was not only sent quickly and received within a few days, but the quality of the kit was outstanding. I didn't know what to expect with this sort of kit, but I really am not disappointed. My communication with them afterwards has always resulted in swift and very friendly replies. I would have no hesitation in dealing with them again. I definitely recommend them.

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.

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.

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:-)

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.
