I ordered it through Mark1Tank. When he recieves it the tanks is still partialy assembled. Mark checks over all the components than runs it out on a proving ground for a a good period of time. Basically he weeds out all the possible faults he can find. www.uktank.org is a club of people who own mostly mark1tanks and have nothing but praise. Mark also has a lifetime gaurantee on his vehicles if they break through normal use(IE no weird or extreme stunts) Also the russian supplier is very reputable. I have sen these 1/6 beasts in person and they are simply amazing. I have yet to see a vid of the leo run so this will be new territory.
