This is a cheap product, about 100 quid. It's just for fun really. It's the type of battery you would find in a large RC car (9V), 4-6hrs to charge. I have yet to find out how long it really lasts. There is quite a few videos on youtube with this newqida train and the feedback is good based on the price its selling for. The range on the RC control is ok for a small garden, but I don't how it would fair in a larger setting. At some stage I would like something Irish in the garden.
