Airspeed/Altitude Sensor

[Fouto]

Hi there everyone!

I've been reading the RCGroups Forum for a few years now, getting a lot of good valuable information from everyone.
I'm an Aerospace Engineering Student, in Lisbon, Portugal.

I've been involved in some engineering contests (SAE Aerodesign and alikes), but now I would like to ask the community a thing.

I'll most probably develop an airspeed (and altitude) sensor, for a project of mine. I'm still collecting some information, but I've got a pretty good idea of what I need to do and how I'll do it (although there would still be a few months before anything comes out, as being a student is sooo time consuming ;))

So, the question is, just for the curiosity (and who knows, an opportunity to make a product available to the RC community), what would be interesting for you in such a unit?

The weight, volume and power needs of this thing would be very low (I believe allowing it to be used in a DLG, for instance); would you like have any maximum values for this?

How about software? Would you need it to be very complex and "bling-bling", or just a decent graphic of your speed profile along the flight?

How interesting would it be to have real time telemetry information (like speed, climb rate, etc.) delivered to the pilot immediately?

And finally, what price tag would you find apealing ;)?

Thanks a lot for any input from you!
