Thank you!

Well, I'd say it is sub 600$ as long as Spectrum TX required.

Well, you can probably understand the misunderstanding if you look at the image (and content) of your first blog post and compare it to this one's. Oh but you deleted it that first blog post, so it's not really a problem anymore, is it?

Interesting concept. Nothing ground-breaking, but good ideas for a low-cost quad. Looks like your team did their homework after all. Best of luck with your kickstarter campaign, it's already progressing nicely as I can see.

Not sure what the point of the 'cable tidy'.. seems like those would not allow the ESCs to cool properly and degrade the life of them over time.   Otherwise seems like a interesting platform and looks like you won't have a problem meeting your funding goals.

It is quite amazing how quickly this went onto the market from the day you made that first post. At the current rate, you guys will be funded within another day or two. The controller is quite an interesting design. Very few people are going into the ARM MCU world for multirotor controllers, so you should consider putting more focus on that. I'm sure lots of people will be interested in the extra power that the cortex mcus have.

Thanks everyone for your support and constructive input.

Regarding the cable tidy and ESCs: the ESCs are actually heat-shrunk onto the aluminium frames, using the frames as a large heatsink (you can see it in the video below).  But you're right, there may be a cooling issue for particularly heavy loads, or instances where the user has replaced the default ESCs (we do supply those ESCs not attached to the frame in case people need to replace them).  We're going to look into it, it may be that we would need to recommend people not use the cable tidies for heavy loads.  That would be a shame, but sometimes there's no easily achievable solution.

@Tian, thanks for noticing the flight controller! Thalamus, is actualy an evolution of our older Forebrain/Seraphim system, which uses the same family of ARM Cortex-M3 microcontrollers and proved to be a success. I think we have a good system here, the fairly fast 72MHz 32-bit MCU does provide excellent cost-performance ratio.  We are planning on releasing more details about the controller later on next week, so keep your eyes peeled.

How come no one creates/redesigns the ESCs.  ESCs seem like they were made for single motor applications but with quad and hex copter not so much.  Hobbyking has some quad based ESC.. but I think there is a lot of innovation there.. we also don't need 4 BEC circuits..  would be cool to see a single ESC that has a 4 motor output.

@Mark Lanning: have you tried these guys? https://groups.google.com/forum/#!forum/openesc I think they were basically tackling the problem from exactly that point of view.
