wait a few months and get Futaba's new 2.4ghz system:
I guess you guys haven't seen Futaba's 3PKS 2.4ghz system yet.. to be released in May. check out the reciever.. tiny and no antenna wires...
The 2.4 GHz module features a short aerial, and is installed in the recess in the transmitter in place of the conventional RF module.
The long telescopic aerial is no longer required to transmit the RF signal.
The Futaba SS system is significantly faster in its response time than existing systems, and offers no less than three times faster HRS FM modulation for fast digital servos, in spite of the 2.4 GHz SS system technology.
The RF module can be set to operate using standard FM modulation or the HRS FM modulation process.
The PK-FSM 2.4 G RF module can be used in any of the following transmitters:
# Megatech T3PK
# Megatech T3PK(B)
# Megatech T3PKS(B)
# FF-3 (T3VC)
# FF-3 (T3VCS
he ultra-compact 2.4 GHz receiver does not feature an external flexible wire aerial. Instead it is fitted with a pair of special aerials inside the case, offset to each other by 90°; these supersede the conventional aerial.
The new system offers two major advantages: on the one hand, the aerials, offset to each other by 90°, are much less attitude-dependent than any conventional whip or flexible wire aerial. This diversity system also considerably reduces what are known as reception "dead points".
On the other hand the receiver is much easier to install and handle, and it is no longer possible to tread on the aerial accidentally and rip it out.
The receiver automatically detects the type of modulation in use, and can switch between standard FM and HRS-FM modulation.
One special feature offered by the R 603 FF receiver is its integral RS232 port.
This output is intended for use with a frequency scanner program, which can display the frequencies in use on the screen of a PC.
This interface can also be used to carry out detailed fail-safe settings.
