from 2268 reviewsAs an aviation enthusiast and professional, this is an incredible model. It's as if it were a real airplane engine.

I baught a toyan 2 cylinder four stroke as a basis for a new engine concept. The quality of the engine is excellent and it is an ideal development mule/platform for some added boost. It arrived a few weeks after I ordered it, safely delivered with advance notification. Highly recommend EngineDIY and their products, and delivery.

I purchased the Retrol HM -01 hit and miss engine and engine mounting kit with the 12 volt blue generator !! I’m Very Very Happy with this purchase ! Everything is beautiful and very well made ! Was Shipped out very quickly ! I’m very happy with the Seller and will use them again !!

Soddisfatto dell'acquisto. Venditore serio, affidabile e molto disponibile.

I Knew about this product via Youtube and I saw it was quite cheap compared to other products. It looks really good, i like it A lot and it was fun to assemble, even if it was quite easy to do

All the small parts are precisely fitted and of high quality. The look is very realistic, and the size is ideal for learning about engines with my children.

This is very well done, excellent quality, and was fun assembling.

I have read the reviews and noticed that they could not get their H76 running. Mine started very easily after I played around a little with the carburetor. Once you get it set right, it starts every time. I like this engine a lot and it has been a great addition to my collection.

Other than it taking 16 days to get, I am really enjoying the BO105.

I was looking for a desk toy that was suitable for a fairly wealthy friend who works in tech, who wouldn't have been pleased with something too cheap or gimmicky, and this was just perfect.

Years ago I saw an original three wheeled autocarriage and fell in love with the engine. Now, several years later, I found this working model of that engine and it is a gorgeous piece of engineering and workmanship. Although I have yet to run this engine, I am admiring its fit and finish, both are first rate and the tolerances are very good with little to no slop in the bearings and shafts. I may replace the Red high tension lead with a more vintage looking cloth covered lead and eliminate the sparkplug boot in favor of a brass clip arrangement. I am going to eliminate one of the batteries in the pack so as to lessen the load on the ignition pack. I really am enamored with this model and am really looking forward to put fuel and oil to use. I am even considering the purchase of a second one in the brass finish so that I can add my own color to the assemblies.

Great replacement hose for my Hit and Miss engines. Good color too.

Fits perfectly in the small recesses in multiple engines I now own. Keep up your amazing work

I have done buisness with Enginediy.com many times, it has always been a pleasure, and there cs has always done right by me. This engine is looking very nice and promesing, I can't wait to put it togheter.

Great 5 star rates
