Hi helorookie,
Many thanks for quick reply.
Hobbyzone.com offers free trainning gear and free shipping. At the moment they offer 15% off parts too. That would save some money. Besides, I send emails to them to ask some questions and they replied quite quickly, while horizonhobby.com seems not yet received my emails
I also called them and they're there to response.
Strange thing is I can not find out their business name. Just the web address (and very similar to Hobby Zone, which is a horizonhobby.com's company). And seems not many people are talking about them.
Anyway, if I feel not confident to order from them, then I guess I should go to horizonhobby.com with higher pays for sure...
