I am the proud owner of a Futaba Force field 9 (aka FF9) working in PCM mode 41.080Mhz. I came across some links saying that before 2011, I will be forced to throw it away or try to convert it in 35MHz (costs of conversion would out pass a new transmitter). In fact 41MHZ has been assigned to military in France, and is already forbidden in Switzerland... While Googling about more info on that subject, I found a lot of people presenting what must be the future of RC transmitter.
Spektrum DX7 2.4GHz from www.spektrumrc.com
In one sentence:
2.4GHz, frequencies collision detection, 4.2Billions keys, 79 persons flying at the same time, bi-directional protocol, no more RF interferences (because only acting at 35Mhz)!
The dream of all helicopter pilot. Currently only Spektrum is proposing a transmitter: the DX7
The transmitter is also cheap: $300, compare to the Futaba 14Mz (2700 euro!!!)
Their FAQ (frequently asked Questions) will better explain You the inside of that new technology.
I will personally fly this year one more time on 41MHz (in France) except if there is already too much crash in my club due to interferences and wait for the DX9 (if a DX9 ever come out)

"Finding
out that the GV-1 Brackets were not meant to be used with
a Caliber 30's clutch hub being directly in the way, I
decided to get creative. This worked out perfect, and is probably better that the normal installation method. I used a cooling fan from Correct, (item 416-141) and used the rim around the top to install the magnet. I then mounted the sensor on the TOP of the fan facing down and drilled a hole and shaped it to fit the sensor. The sensor now sits above the fan facing down, and is receiving at a 97% (which is very good). It also is mounted to the frame instead of a long bracket, and doesn't move around. This method also makes for a much cleaner look, as there is no brackets used to mount." All credits to sgunn911, his gallery at runryder and website CUSTOM-RC.COM |
| "Installing
the GV-1 sensor on the Caliber 30 can be tricky because
the fan, where the magnets are mounted, is above the
clutch. I've seen many modified brackets on the web to
'bend' the sensor around the clutch. However, I found

the future is now here!
Reality
I do not own currently a FMA copilot, but I plan to acquire one as soon as a CCPM version will be available. I want to use it only in some case: panic or brain short circuit. Many people complains about this new gadget, arguing that it is better to learn alone, yes this is true. On the other side, investing $100 is not an issue if you avoid 1 or 2 crashs.

Overall view of my 1st caliber
24.08.2002 Add a dual battery system for more safety. I have no heli with only one battery. Here is why:
| Problems | 1 battery pack | 2 packs + mechanic Switches | 2 packs + Electronic switch |
| Additional cost of system | reference | + 55⬠| + 180⬠|
| Open circuit between battery and switch's pack | Failure | Redundant | Redundant |
| Open circuit in one of the pack | Failure | Redundant | Redundant |
| Battery short circuit in one pack | Failure | Failure | Redundant |
| One pack not fully charged | Failure | Redundant | Redundant |
| Switch failure (assumes between RX and backup sys) | Failure | Redundant | Failure |
| Battery connector from backup system to the receiver | Failure | Redundant | Failure |
