Why would they "lose margin"? How did they "blow it"? Both of you are forgetting that the Noble radios are NOT 4Ch radios...they are (with current firmware) 12Ch radios, and are priced WELL below any others with that many channels. The Futaba 10PX costs $800 (or more), and the 7PX is $600. The Sanwa M17 (only 4Ch) is also $600. The KO Propo EX-NEXT (also only 4Ch) is almost $500. The Spektrum SX5 Pro (only 5Ch) w/ 1 Rx is $400. The only other 'competitor' in the same price range, with almost-as-many channels (8Ch) is the Radiolink RC8X, for $20 less ($280)...but, the "Noble" name is more established, especially among racers.

Whether, or not, the NB4+ is "worth it" is pure speculation at this point, as the full spec list hasn't been released. While the increased manufacturing cost for the "brighter screen", and "larger battery" (we're all still assuming that's in reference to the 18650) is probably negligible, the cost of adding the USB-C port is probably costing them a bit more, as the 'cost' involves more than just the cost of the physical parts. To comply with 'standards', the circuitry is more complex, increasing cost. There's also additional R&D in creating said circuitry. Something else to consider is that, even though shipping costs have given up over the past several years, FlySky never increased their prices (unlike almost everyone else)...so, is safe to assume that they have finally decided to recuperate their losses in that area by 'adjusting' pricing to offset their worldwide shipping costs. Put another way, they're just playing "catch up" to all the other manufacturers who increased their prices 2-3 years ago. Personally, I see nothing wrong with that.

Even at $300, the NB4+ is still 1/2 to 1/3 the price of equally-capable radios from most other manufacturers. On top of that, receivers cost considerably less than those other manufacturers. Then, there are the 'advantages' all Noble transmitters have over other brands - the ability to use as a PC controller (not that many use this feature, but it IS there), the ability to 'rotate' the wheel to your preferred position, the far-better-designed menu interface. Finally, there's the advantage so huge, NO one else has this - the removable battery base. This, alone, makes it shine above all other radios, as you can remove the base to recharge the base battery, while continuing to use the transmitter. Then, once the base battery is charged, you reattach it to the radio, and stay charging the internal battery...all without EVER having to stop using the radio...plus, the base battery can be used to charge other devices (cell phone, tablet, wireless headset, etc.

The point is, instead of just looking at it from a "they're increasing the price by $100" perspective, look at it from the point of all the advantages of has, how many channels it supports, the different types of RC vehicles or can be used with (essentially, EVERYTHING except planes, helicopters, or drones), and the "long term cost". What do I mean by "long term cost"? Consider how many vehicles, maximum, you might have bound to the radio. Then, subtract 1 from that figure (since most radios come with 1 receiver). Now, for every radio you'd consider, multiply the remaining number of receivers by the cost of those receivers, and as to that amount the cost of the radio w/ 1 included receiver. In the end, even with the NB4+ costing $100 more than the NB4, I'm willing to bet that the "long term cost" of the NB4+ is, at most, 1/4 the cost of the other radios you'd consider. Futaba receivers tend to be in the $50-100 range. Spektrum receivers cost even more. However, receivers for the Noble radios tabs to be in the $30-45 range, work the most expensive (FGr12B 12Ch Rx) costing less than $60. That's a HUGE cost-savings compared to the other brands. My guess is, that $100 difference isn't looking at that bad anymore, is it?
