Analog Servos and 2.4 GHz
I believe while reading an article in MAN about the new Airtronics 10 channel radio a comment was made that analog servos are not or may not be compatible.
I'm considering 2.4 GHz but I have too many analog servos that would then be trashed if I converted. So, my question are:
Is this (analog compatiblity) an issue on some or all 2.4 radios? I have read little about this so it may not even be an issue. I'm very remote and hands on with the various radios is difficult. If there is an issue, is it by radio manufacturer or model type?
When folks change over to 2.4 do they do it for everything and get out of 72MHz or go to 2.4 for their better planes?
Is there more hype i.e. salesmanship etc. in 2.4 or is the need that significant? Liability, of course is a very real issue, as is protection of a valuable model. Since I fly in a remote area (club) and have thus far not seen, but heard of, interference bringing a plane down, yes, there is risk, but it appears relatively small. Is my assessment valid?
I read a thread in which a member was trying to cut through all the marketing in order to decide which is the best 2.4 radio for him. He too was in a remote area. It appears to me, continuing to follow the different opinions on RCU may be most helpful in making up my mind of which 2.4 radio to buy along with comparison of specs. Hands on is not feasible, so opinions are sure welcome.

Servo - Wiring Diagrams = use with other brand RX.
Futaba FAAST - R6014FS receiver - servos do not work or sporadic.
Servo - Compatibility between age and brands

RE: Analog Servos and 2.4 GHz
With regard to servo compatability with the Aitroncis 10 channel radio, the manual (page 7) notes the following :
"Due to the extremely high frame rate of the 92104 10 channel receiver (included with your SD-10G radio control system) operates at, we strongly recommend the use of digital servos, if you use analog servos and experience problems you will need to upgrade to digital servos or use the Airtronics 8, 7, or 6 channel 2.4 GHz receivers. These receivers operate at a lower frame rate, therefore, analog servos can be used without an issue."
I'm not sure if other brand radios have this problem or can meet the latency performance of the SD-10G radio and the 92104 10 channel receiver.

A friend has the SD-10G, so I can attest to the fact that the 10 channel receiver does have this limitation. Unfortunately you do not have the option to run the receiver at normal frame rate, as Futaba does on their new generation receivers, also having the high frame rate on all channels is of questionable value.

RE: Analog Servos and 2.4 GHz
Only the low end sevos are effected by the hi frame rate. I have an SD10-g, and some of my older low end servos (all brands) will not work with the 10 ch receiver, but no problems with the 8 channel receiver. Digitals are not required though. I dont own a single digital servo, but fly only Airtronics 2.4.

RE: Analog Servos and 2.4 GHz
I have an SD-10G and the high frame rate (~110 Hz or 9 ms update rate) does cause problems with some analog servo's. So far, I've had 2 that have failed (on the ground) and around 5 or 6 others (Hitec, JR, Airtronics) that buzz, don't center or have weak output. Worked well with Spectrum previously or, if not totally failed, still work with other systems. But, then, I have other analog servo's that work well with the SD-10G. The high frame rate can't be turned off. On the Futaba HS receivers, I believe you have a choice.
