Thanks... I should have been more specific - I'm talking about the Pro roller - looks to have a bunch of carbon fiber and alu - have heard it's bulky - and heavy.. Definitely not getting an RTR. One of the reasons I'm even thinking about getting one is because I have extra engines laying around, and yeah, the pro roller is so cheap.. As are the spare parts btw. One got auctioned off a couple hours ago for €120(from a shop - new price €149)
