hello guys
i finally managed to get the 2.4 radio system from frsky. the DHT-U telemetry unit.
Hitec Aurora 9 is the best transmitter system I had used , but does not feature PPM Sum . PPM sum feature is possible now with FrSky DHT-U. FrSky DHT-U is firmware upgradable two way transmitter module can be clamped to the transmitter handle/antenna. All-in-one combination of telemetry capable, in-built display and alarm threshold settings featured.
This transmitter module can be usable with
Hitec,
Futaba,
JR/Spectrum
T9x.
Compatible Receivers with DHT-U transmitter module
Mode of DHT-U (Selectable on module menu) Compatible Receivers
V8 _Mode Non-telemetry receivers (V8FR-HV, V8R7-HV, V8R7-SP, V8R4)
D_Mode Telemetry receivers (D8R, D8RSP, D6FR, D4FR)
My choice is D8fR 2 receiver. Because
RSSI (PWM) and CPPM (8 channel) output ,
Lighter weight and physically smaller,
Fail Safe
telemetry capable
some pictures are attached and PIN diagrams.

Done some changes now.. Aurora 9 with dht .
Need to create a new female connector on pcb and now it works flawless..
Nice but some messy work ! i did it for my module about 2 months ago! but buzzer was damaged ! so any how i dont use it for FPV flying,so thinking to add when required!
Works good! cheap receivers with telemetry!
i lost my buzzer too.. replaced it with lipo alarm buzzer ,.. works flawless.
if it was only soldered we could have removed easily ! but its glued to PCB that's the problem. :)
