The kit

The engine comes in a resealable ziploc bag and contains only the engine and a very small sheet with a drawing of the engine with colours and the requirement to add wire to it for the pushrods.

The engine is a very nice rendition of the original and for a number of models it would just need the wire attached to the front to make it correct. Unfortunately some aircraft, like the Swordfish, require the piping that runs behind the engine to be added to make it look correct, whilst it doesn't come with the piping it does have locations for where the bits go. The casting has very fine raised details of the bolts and fins on the cylinders that would come up beatifully with careful painting.

The instructions as I mentioned are very basic and I think they fall down slightly in the painting requirements as it seems that not all of the engines were the same colours. I would suggest that you find a photo of the engine you want to build and use that rather than just relying on the instruction sheet.

A point to note, the squares on the images below are 1 cm by 1 cm.


This is a very nice casting of an engine that has many uses, as such I highly recommend it.
