Raidentech is not a manufacturer. They sell ARFs from multiple manufacturers.

Nitroplanes, and several other online vendors, sell most of the same planes. A lot of them are also sold through ebay sellers.

The 'standard' complaints (no matter which "brand" is on it) are: terrible instructions, no customer support, poor hardware, inconsistent build quality.

For every person who bashes these models there seems to be another person who likes them.

I get the impression that some models are not really "ARF" and require a lot of 'fixing and fitting' during the assembly process.

If you know how to find and fix weak spots, and don't need detailed instructions, go for it if the price is good.
