| | I am new to RC. After hours on a flight sim, I think I am
| | ready to invest in my first radio system and a .40 size
| | electric trainer aircraft. After some research, I think I
| | am pretty well set on a 2.4 GHz radio. Futaba has just come
| | out with their 6EX, a designed 2.4 system. The alternative
| | is the Spektrum DX-7. I would appreciate input on the
| | differences between them and the pros and cons of each -
| | anything to help me make an informed buying decision. TIA.
| |
| |
|
| I don't own either one but have talked to several guys that do. The
main
| complaint against the Spectrum is that it has two receivers linked
| together by a cable and they must be orientated approx. 90° from each
| other. Not a problem in a large airplane but can be in a small
fuselage.
| The Futaba has one receiver with two antennas on it which is much
easier
| to install.
|
| If I understood them correctly there is a difference in how they
| operate. The Spectrum uses two channels out of 41 or so and picks the
| best of two signals. The Futaba sequences through the channels and
| rejects anything that isn't right and moves on. To me, this fits the
| definition of spread spectrum in that the signal is spread over all of
| the band.
|
| My vote (for what it's worth) is for the Futaba. But, I am mostly into
| sailplanes now days and the fuselage is usually pretty cramped in the
| ones I have, and plan to have.
