Attention: RC-CAM.com will be closing down August 2021.The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.
We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.
RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.
We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.
I just found a post by you (http://www.rcgroups.com/forums/showthread.php?p=5721973#post5721973) that shows the JR NET-J72P port pinout. I am still wondering if I took a Spektrum DM9 module for the JR XP9303, could I "hack" it and put it into a JR XP7202 TX and make it 2.4 GHz? If I do this, I would not want to retain the 72 MHz mode. I know that from looking at the "hack" for the Assan module that I would need to cut the three wires that go to the PC board (black, yellow, and red wires located on the center board) – see attached picture. I think that they are: battery +, –, and PPM signal
Has anybody tried to take the "guts" out of a Spektrum 2.4 module and use it to make a JR XP7202 into a 2.4 TX? Since the DX7 is basically a 7202 on 2.4 GHz rather than 72 MHz, I would think that the JR module (DSM2 AIRMOD w/AR7000 JR-Compatible [sPMMSJR7]) could be "opened up" and the "guts" used to replace the 72 MHz RF. Am I looking at it too simply or could this be done?
