This is the Sanwa/Airtronics and LRP Electronics Entry-Level Radio Week Video #2!

So … what are the binding procedures? What is dual/rate? What is EPA? And are all the transmitters and receivers compatible? Do an LRP A2-STX Pro Transmitter bind with an LRP A3-RX Deluxe Receiver? Do an LRP A2-STX Pro F.H.S.S. bind with an LRP A2-RX Pro Receiver?

Watch this video and find out! The instructions should solve any basic questions and help setting up the LRP A2-STX Pro for a new owner. Here is an overview of the video:

0:03 Introduction
1:05 Basic operations
1:15 Installing
1:22 Binding
1:44 Trimming
2:03 Normal/Reverse
2:30 D/R and Steering EPA
3:03 ATL and Throttle EPA
4:00 Test Run
4:20 Compatability/Binding Tests

LRP A2-STX Pro 2.4 Ghz 2-Channels REVIEW
These radio systems are, to my knowledge, some of the most widely used LRP 2.4 GHz systems as they are sold seperately and at the same time included in an variety of the LRP RTR (Ready-to-Run) models, like the LRP S10 Twister or the LRP S10 Blast. They have some nice extra features, like dual/rate and full EPAs, not too commonly found in RTR Radio systems. The systems also include a Fail Safe Function (not included in the demonstration). Only downside may of course be the housing which is based on previous 27 MHz AM models. It is provided with an antenna (that could potentially break off as happened with my LRP C3-STX) and the fact that it requires 8 x AA batteries.

To my knowledge, LRP have now replaced the A2-STX Pro and A2-RX Pro/A3-RX Deluxe radio system with the LRP B2-STX transmitter and LRP B2-RX receiver. The housing is still the same and therefore the general options and settings looks to be identical. The B2-STX should however include some improvements on the steering wheel and comes standard with the F.H.S.S. technology. Performance wise they should be very similar to the LRP A2-STX Pro F.H.S.S. version and the LRP A3-RX Deluxe F.H.S.S.

What is F.H.S.S.?
In order not to swamp the demonstrations with too much text and information (there is too much already as it is) I decided to place the information about the F.H.S.S. system here. The LRP A2-STX comes in an F.H.S.S. version, most commonly supplied together with the LRP A3-RX Deluxe F.H.S.S. “F.H.S.S.” stands for ‘Frequency-hopping spread spectrum’ and implies that the radio signal is constantly ‘hopping’ between 2.4 GHz sub-frequenzies (‘spreading it’s signal) which in other contexts would make it difficult for ‘spies’ to ‘easedrop’. In this Hobby context it means other signals have a harder time interrupting or causing interference. The downside, as I understand it, is that it may cause delay. This delay is what the F.H.S.S.-2 (and upwards) tries to remedy. I suspect using F.H.S.S. transmitters with non-F.H.S.S. receivers, and vice versa, will disable the F.H.S.S. system. I also suspect the A2 and B2 systems to be compatible but have no personal experience to base any of this on.

What is “binding”?
In case you’re wondering what “binding” means and why it is important: Digital 2.4 GHz Receivers and Transmitters needs to be “bound” together to work and “speak” to each other (and therefore not interfere or be interfered by other 2.4 GHz radio signals in the same operational area). Not every 2.4 GHz transmitter and receiver can be “bound” together however. Not even transmitters and receivers of the same brand. Which transmitter and receiver is manufactored as a “pair” and can be “binded” is therefore extremely important as they will not work together if not compatible.

That’s it! Hope you found this video and information useful?

I would love getting some feedback!

… and in case you’re wondering: The RC model featured here is the Tamiya Thunder Blitz 1/10 4WD On Road Model from 1997.
