## 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.
