PRODUCT: Trends UK Haynes Build Your Own Internal Combustion Engine(www.trendsuk.co.uk)Trends UK Haynes Combustion Engine

DESCRIPTION: A construction set for older children to build a working model of a petrol car engine, with electric motor, ignition sound and illuminating spark plugs. A Haynes Assembly Manual is included. Contains over 100 parts and tools. Requires 2 x AA batteries (not included). Suitable for children aged 10 years upwards.

GOOD POINTS: The Build Your Own Internal Combustion Engine from Haynes is a brilliant way to give older children a real insight into how a petrol car engine is built and works.

Anyone who knows anything about cars will have heard of Haynes, and this set will not disappoint with its high quality and attention to detail. The set is very reasonably priced for what you get in return, and contains a fantastic number of parts (over a hundred) for your child to have a go at assembling a simplified version of a real four-stroke car engine. There are obviously components that would appear on a full-size engine that do not appear on the model, as well as components that appear on the model but do not function as they would on a full-size engine, however the overall build is certainly impressive, both in size and detail, and something your child (or dad!) will be proud of!

All the parts come in sealed plastic bags, and although these parts are not numbered, your child is usefully encouraged to spend time identifying them using the accompanying Haynes Assembly Manual - great practise for helping them understand one end of a car from the other.

This mini Haynes manual is simply brilliant and is familiar in layout and style to its full-size version. The technicality of the 'build' means that the product is aimed at older girls and boys, but the manual does an excellent job of explaining a fairly complex task in a sensible and uncomplicated way, including detailed step-by-step instructions and related (black and white) diagrams on how to build the engine, basic principles of how a full-scale car engine works, and even a useful glossary of basic engine terms at the back.

A screwdriver is included to secure the model together using the screws provided, and this is the only tool that is required for the assembly. In order that the pistons work smoothly, it is recommended that you coat the bearings in a little vegetable oil (not car engine oil!). Once the model is successfully assembled, your child can watch the various parts moving by connecting up the distributor and electric motor unit to the battery box (for which you will need to insert two batteries), and 'starting up' the engine. The engine will run for approximately 5 seconds, with illuminated spark plugs and a sound chip which reproduces the noise of a real engine starting - great stuff!

In our opinion, this is a truly unique kit which we would certainly recommend for any older child interested in cars and engines. It is fun, educational, challenging but not overcomplicated, and incredibly rewarding once completed...a great gift for the mechanically minded!

BAD POINTS: None, other than your child may need some help with some of the more 'fiddly' bits.
