Many people rather pay HKD$130k for a private car than a 1/4 tank, so that I think the people living in foreign country just like you is very very lucky and happy.
I guess even in overseas countries, there are not many hobbyists who can afford this large scale R/C tank as either:
You need to live in a house with a really large private backyard or a farm.
Need a flat bed truck to transport this monster to other sites.
You will probably break the bank account.
Your parents won't let this monster inside the garage.
In Hong Kong, hobbyists are some what lucky that most general R/C items are not expensive so even a student can save up and enjoy the fun of R/C, eg. Mini-Z.
