Thank you for the link to banzaihobby...one important thing to note is importation tax from US (about additionnal 20%)...but even with it, it could be profitable..
I don't really want a lot of tanks, but I would like to have a R/C tank that be also presented in static mode.
Apart price, the only drawback of tamiya R/C model is painting...
I'm not so bad to build (I like mount/unmount pieces) but painting...well I'm not so good..
