First of all wait for more opinions i don't hold the absolute truth...
The spectrum system which i dislike personaly (overpriced and low
capabilities) can use the so callled satellite receivers ie additional
receivers for diversity, different aircraft orientations can affect the
If you will use an LPC based autopilot (or any paparazzi autopilot for
that matter) all you need is a receiver with PPM output.
I would use your existing mx16 and convert it to use the Frsky with
telemetry FHSS system which i think is one of the best i have tried and
believe me i have spent a fortune on every imaginable module and
protocol there is.
or convert the spectrum one with a module like this or similar as it is
out of stock
or buy an el cheapo 9X radio again with the above module-rx pack.
I use a modified 9X with an ARM cpu and OpenTx in it for everything i fly.
Those receiver work fine with Paparazzi

i hope i elped somewhat

I'm completely new to PPZ and only have some (not much) experience with

Now I have to buy a new radio control (among the rest) in order to build
a SUMO-like drone for meteorological measurements at university (and it
should be done quickly as always at the end of the year).
The plan is to build a SUMO-like prototype which should require as few
work and troubles as possible in order to have a working system for
learning first and then address to modifications later. The plan is to
work through the bill of material at
http://paparazzi.enac.fr/wiki/SUMO/prepare_electronics and order the
parts from different dealers. However concerning the radio control I
don't know what's the best to do.
In the SUMO description
(http://paparazzi.enac.fr/wiki/SUMO/rc_transmitter) the Futaba T8FG and
the Futaba T7C are used, but in fact I would tend to the DX8 radio
control which allows to use the receiver satellites (some thing I do not
understand fully yet, but which seems clever to me).
However I figured out in the wiki that "Proper Spektrum support is only
provided for the STM32 based autopilots. ", however I am not sure
whether we need to have a Umarim lite for building a SUMO or if the
Umarim could be replaced easily by an APOGEE (with all the sensor
connections and so on). It is important for me first to have a more or
less trouble free system, in order to learn how everything should work.
The RC should be easy to use (i.e. 2,4 GHz) have some additional
telemetry (especially a vario beside the PPZ system if possible) and
allow a range of up to 1-2km (as usual radios do as I understand). Eight
channels are preferred (even it is now used only with a flying wing
which just needs 3 channels for throttle and 2 rudders). A three way
switch is also important for the autopilot mode it seems. Costs for the
RC including receiver should not exceed 400 euros (550 dollars).
As far as I understand any other RC than Spektrum needs ppm-support,
which the Futaba seems to have. A ppm-encoder should be avoided.
Can anyone please give advise, which RC can be recommended for this set
up (or in general for ppz-support)?
Thanks a lot!
