Review: Absolutely hooked - Having put one of the cars together as my first attempt at these superb models and enjoying every minute, I went for the Bigboy truck. The more time I spend building this, the more I realise what a fantastic product it is. The thought that has gone into these is amazing. This one would be a difficult first go, but once you work out the instructions, and what the symbols mean, they are easy to follow. I am half way towards building the Bigboy truck and still enthralled with it. Shut myself in the shed, with the radio on and a cup of coffee, and I lose track of time. Some of the parts take some persuading to come out of the cut-outs and it's no good using brute force as breaking one of the pieces would cause problems. Everything fits together superbly, and it's great when you start to see it shaping up. I love them, and going to spend a fortune on them in the future, but they are worth every penny.
Review: Good model - Good to make & looks good when made up alongside the truck

## Questions & Answers

**Q: what is the size of truck and trailer combined?**
A: Truck is 14" and the trailor is 6.5"

**Q: what type of wax should be used for the gears?**
A: Well I use a nightlight candle , or the piece of wax provided , but I don't think I've got the answer yet ! I'm yet to get one of the very complex kits to work satisfactorily.

**Q: Can they be painted during the build process**
A: My Hubby didn't complete this model because there were too many fiddly parts. I think it would be difficult to paint during the building process.

**Q: Is it possible to buy spare parts if broken**
A: I have ordered 2 replacement parts via the ugears website. On both occasions, ugears sent me two copies of the broken part. Their follow-up service is excellent.
