Funny you should say lol ive just dug mine out and taken them to work as we are a bit quiet at the mo and given them a going over and got them running lol. I have a schumacher menace 4x4 with a size 21 engine in it and a kyosho macca f1 4x4 with a size 12 engine in it. To be honest the kyosho is the more fun too as the menace is just to fast unless you are in a field so it has room! ill get some pics
