Toyeast have Radi-book for $49.. and they r truely proportional... I am very temped to get it, as it is a lot cheaper than Mini-Z..
Do u think I should get it?
Btw here is the image of it
Edit: I also notice that HLJ also have it, but for $68.. It also interesting to note that the weight is 650g instead of 1.1KG as stated on Toyeast.. maybe that how Toyeast make money from? (by make the weight 2X more heavier in order to charge more on shipping)
