Basically this IS the same as the existing 2A relay solution but I've changed the physical orientation a bit, added some mount holes, changed the size of the terminal block and added another LED or so.

It's also redesigned to make it easier for me to make a few variants that some people special-order from me.
------------------
A new version of the popular RCS-RL2A relay. The configuration has been changed to allow for easy mounting with a pair of 2mm mount holes provides behind the relay. There are now also two status LEDs to let you know at a glance what the state is.
NOTE: For inductive loads (motors, coils, solenoids) we recommend using a back-EMF blocking diode across the terminals to prevent reducing the life of the relay contacts.
SPECIFICATIONS
Switching current: 2A
Switching speed: 0.05~0.10 seconds (safety feature aspect - see below)
Output connections: Common, N/O and N/C
Size: 25 x 25 x 14mm
Weight: 13g
Servo lead length: 150mm
Input voltage : 4.0V to 7.2V
SAFETY FEATURES
Requires at least 5 good frames before comitting a switch to a different state
If TX signal is lost, reverts to relay default setting (after ~0.5sec of constant loss)
Relay outputs isolated from R/C circuitry
Oh yes, this one is programmed with ASSEMBLY, so it's so much l33t3r than the previous model
