I'm blown away by their diversity in terms of scales, electronics, and styles. The options are amazing, particularly in the extended range. Window-shopping on ReBay, it's like I never see the same piece twice. How can they afford to produce so many different models? Indeed, some of the ones I salivate over have been sitting on ReBay for quite some time. I'm curious: what's their business model in comparison to other builders, both big-time and boutique? Is it one guy going bonkers 24/7 or a big team?
