The Retrol HM-01 engine from Stirlingkit not only looks good but it runs great as well, So many of these models come from the factory set up to run as fast as possible, The opposite to what enthusiasts want, but they got it right this time.
The quality of machining of this engine is second to none. the fit/finish is perfect.
The wooden base really sets the engine off and is worth the few extra dollars to get it, Taking it from "Toy" to "Scale Model".
The engine fired up very quickly after the initial build without any issues.
It come with a glass drip lubricator (as prototype) for the cylinder along with two lubrication cups on the crankshaftshaft.
Overall i think this engine equals the quality of something you would expect to pay 4-5x the price for in the USA or UK.
It really is a no brainer, GET IT BOUGHT
