unfortunately probably cant count that. there is no hint of similarity between matrix math and pecking away at assemlby in embedded controllers. and personally i was VERY pleased to see a 4 year engineering degree.

If you count what I am currently doing in mathematical programming (like protocols but with 4 by 4 matrixes of unkowns) I do at uni as reverse engineering then 3 a week. And that just first year of aerospace engineering! I would hate to see a 4 year maths degree!

Also, just from observation, you can see nothing magical happen between the two antennas to make the output any different to the input.

Actually, I lied. We did touch on hex-coding and finding what manipluations happened when last semester during basic electronic/electrical engineering but I stress that we only just touched it.

No I meant I wouldn't stand a 4 year PURE maths degree but I can certainly handle engineering!

Yeah. It can be hard to explain to someone I have a flysky turnigy 9x, but replaced the module with a FrSky one. The response is usually
". . . what?"

Ive seen people type FrySky in many forums. Is that just an error or another brand?

Is the new 9XR has the RF module as the present TURNIGY 9X or it will be available only as dsm2, dsmx without any module.

Thanks

Many people have mentioned that it is not the new Turnigy 9X and they could be right. Only posted it to see if people liked it and since FlySky sells the same radio as Turnigy, Eurgle and others who knows.
