Receiver
What is the most important thing in a model? Exactley, a reliable receiver, without that, nothing would work.
When the time of 35MHz was over, I stood in front of the question which system I should go for. HoTT wasn't available in those days and thats why it became Spektrum that isn't available anymore today.
Should it go faulty, then I'll probably change to the MC32 with HoTT and built in an extra DSM2 module to be able to still use my existing receiver. DSM2 became old already and Spektrum only uses his new DSMX protocoll but I never had any problems with DSM2 and a DSMX is also backwards compatible to DSM2, so I'll gonna stay a long time with that.
I'm only using OrangeRX receiver because I had 0 faulty ones, they have a very good range and a high tolerance according to under voltage. And this with about 400 to 500 flights per year. I also will only introduce here transmitter which I have used by myself.

Good to know
With 2,4GHz many things in the model hobby changed and also the security was raised very much. There can't be any frequency collisions anymore and also the possibility of disturbtion is much lower, but there are still a few points which would be good to know:
- There are no more quartzes. A frequency collision is practicaly excluded.
- 2,4GHz is not cross compatible. A Graupner receiver will not work with a Spektrum transmitter, every radio has to "talk" the same protocol.
- 2,4GHz can't be used for submarines because the range reduces under water immediately to only a few meters.
- All well known brands achieve a range that the model can't be seen anymore, if there is now stand 1,5km or 4km on the package is irrelevant.
- If there are at least two antennas, they should be fixed in a 90° angle.
- if there is only one long antenna, it can be fixed in a slight arc to optimize the range.
- There is no reason to get the antenna out of the model, only with carbon fuselages this must be done.
- A failsafe programming is duty, at least the engines needs to get the throttle cut if the connection is disturbed.
- If using only one antenna and if flying more far away then 200-300m, a satellite is highly recommended.
- At models with much carbon or metal, a satellite is also highly recommended.

Name: R610
Manufacturer: OrangeRx
Sold by: Hobbyking
Warehouse: Worldwide
Channels: 6
Range: Parkflyer
Protocol: DSM2
Price: 6€
Features: Followed by the R615. The satellite connection at the R610 is there, but it can'tbe used in real life. If there is a operation from the satellite comeing, the receiver will only forward it to the servos every 0,5 seconds. Thats why go directly for R615 with diversity.

Satellites
Satellites are often false used by thinking that they would extend the range. That is definitely not true. Satellites are used to avoid radio shadows. It doesn't matter where the receiver is built in in the model, somehow the sight connection between receiver and transmitter will be blocked always. With full composite or wood, this doesn't matter, but with carbon or metal (tuned pipe etc.) it can happen that the radio connection will be disturbet. In that case, a stellite will be mounted that way, that he has sight contact to the transmitter, when the antenna from the normal receiver is hidden. Similar to the way of how to fix a antenna in the plane. If one antenna shows straigth to the transmitter, the other antenna should show with her full broadside to the transmitter. Thats why two antennas should be mounted in a 90° angle.
In opposite to former 35MHz systems, there is today no more reason to bring an antenna to the outside, except carbon models.
