I guess I wouldn't buy any ARF with the expectation of being able to get replacement parts.

Many of the low price importers have the reputation of selling a run of ARFs and having zero parts availability. They do not have warehouses full of parts and accessories. They are in the business to sell planes, not parts and accessories. Nitroplanes is one of many that seem to follow this business model.

Even the 'big boys' like the Ace, Global, Hobbico and Horizon conglomerates (or mid-size operations like SIG that concentrate on just a few brands) only have a certain number of spare parts built for any particular model while it is in production. When a model is discontinued, and those parts are gone, it is very unlikely that more will be made.

I think that's one of the reasons why so many people consider ARFs to be disposable. If parts are available, the cost is often close to the original ARF price. Since there are no plans or templates, you can't always make your own parts, so the whole thing goes in the trash.
