RE: RC Tank Shops/Manufactures
Raidentech aren't known for their great customer service, but their prices are very good. It's a trade-off. I had a lot of back and forth with them over an HL Panther that broke down within an hour and a replacement that did the same thing. The third one worked. I subsequently bought a Tiger from them and had no problems with it.
I don't strongly recommend them, but certainly don't flatly condemn them either. Individual experiences vary. If you're cheap or broke (or both ) go for it. If you don't mind paying extra for the goods and for service that you may not need, better to go elsewhere.
