Mixing Esky receiver parts.

My new HBFP V2 came with a defective factory Receiver (extra electronic part loose inside caused a short of main motor (esc or gyro)) --- A friend within RC Guides sugested using 72 Mhz receiver parts with a 2.4 Ghz Receiver.
This is what I did: used the part that connect to battery with the part that has the 2.4 antena and voila now I have a 2.4 Ghz working receiver for my HBFP V2 new heli (all parts are Esky brand and fit perfectly inside the new 2.4 Ghz receiver) also just to prevent a further short circuit I first checked + and - polarity on the plug that connects the Receiver antena and the receiver for the battery.
