About the main blades, I bet that the Rail 556's would perform awesome. However, I would hate to just have the Radix v2 554's just sitting unused or sell them at a fraction of the cost when they track so well. Are the Rail 556's that much better than the Radix 554 v2's?
About the ESC, my T550 breaks the 130A barrier quite often. The CC ICE100 doesn't seem to mind, but it makes me nervous. It is reassuring that Matt recommends in the manual (and you use it) the CC 120HV ESC for 6S application. I was just wondering if the new CC 130A ESC would be an even better option when running on 6S.
About selling the helis, I have sold many parts in HF and rcgroups, but I have never sold bigger ticket items like full helicopters. Is it better to sell each helicopter as ARF package deal, or is it better to part out each helicopter into individual components?
