I have a QQ190 with powercube, purchased new from TBS approx 4 weeks ago. So far it’s been flying without a problem (sensational), VTx set to 500ma using a Spektrum 4649t diversity Rx with a Spektrum DX8. Went for a fly at my local field yesterday and discovered my video output and RC range had both dropped considerably for no apparent reason. The VTx is now equal to about 25~50ma and I lost RC control twice. This is my test field, I know it well and up until now I have had great video range and never lost RC control. I have tried changing power output and it makes no difference and the drop in RC range has me stumped. I don’t do acro, just speed cruising fpv. Haven’t had any crashes yet, so I can’t put it down to impact damage, it has just happened out of the blue. I think the VTx and Rx use different layers in the cube(?) which makes me wonder why my video and RC have both lost range simultaneously. Can anyone suggest what I do from here? I don’t understand the cube well enough to know what to do or look for to get this sorted. Any help much appreciated. TIA.
It would seem that updating to OSD FW 2.02 had locked my VTx power output to a low setting. Even though I could access and see the different outputs/bands and channels, it was locked at somewhere between 25~200ma at a guess. Reverting OSD FW back down to 1.72 has solved my problem and can now access all bands and power up to 800ma working. Can’t explain the RC dropout, perhaps just a coincidence.
