I purchased a ready to fly quad from 3DR. with the works. The video receiver was back ordered so I removed the Lawmate TM-241800 Tx, camera, Minim OSD and began my journey. I have years of past RC heli and plane experience and I'm good with computers so I manged many successful flights along with waypoint guided flights using the mission planner. I have been very satisfied with my purchase. The video receiver arrived a week or two later but without a monitor or goggles, I kept the FPV items off of the quad.
My bosses loved the aerial pics I took with my Gopro and had a job for me to perform using the potential of FPV.
I order video goggles, a monitor and some cloverleaf antennas, these items are in the mail.
Christmas Eve day, I have mounted all FPV equipment to the quad and use the TV set to check operation. All seems good so I take a flight in my yard at lunch time, this is great stuff, the wife watches the video live on the tv set and I am ready to demonstrate for my bosses at work. We have a small monitor there that I hook up. Mission planner is running on the laptop and video is playing in the office. So far, I am a hero.....
Takeoff is fine, I head to the back of the property about 50 feet away and start a slow climb to take some photos. Then it happened. My failsafe is set for Return To Launch, the quad climbs to 40 meters and begins to head back, but its over trees and there is some wind causing it to drift. I lower the throttle stick, the quad responds momentarily and drops, then recovers. I am trying to bring it closer, it responds again and perches itself atop a tree and out of sight till the next (Christmas) day. I have not looked at it till today.
OK, so there's that range check thing. I put a flag on the servo controlled camera mount so I could monitor it from a distance.
I have now noticed a substantial difference in range when the Video TX is powered on, 12 paces as opposed to an easy 30 paces. I tried it a few times, powered the video tx on prior to the control system as well. Same thing, my RC control system range is cut in half when the video TX is powered on.
Due to my lack of knowledge in FPV, I purchased an already configured system feeling that I was safe. I understand that both transmitters are in the 2.4Ghz range and that the DX8 uses spread spectrum frequency hopping technology, so I thought........
The Lawmate Tx came set on "1CH" all dip switches up, still the same.
Am I alone, can this system work?
All comments will be appreciated, except for "why didn't you range check it first"!
