Thank you, I joined the yuneecpilot thread and I so see a lot of complaints about the camera. I've also seen video footage from the H on YouTube that looks amazing and then some that is pretty bad. Seems like a quality control problem.
Honestly I really like everything about the P4 better except it being a quad compared to a hex and the looks of the machine. Maybe I'm just being too picky.
Impressing the customer with your photography gear has value. A really good way to mitigate this problem since the P4 looks more like a toy is to buy a GoProfessional or Microrapter hard case that makes you look like you're serious about videography. Also buy an OSMO to supplement your indoor shooting options. You can get really creative with an OSMO.
Bottom line, the P4 is way more sophisticated than TH from a software point of view. For instance the software will show you when your over exposed in the display with stripes, letting you know to pay attention to that particular scene and correct the issue, not available on the TH. One touch exposure, just touch the iPad screen and the GO app auto corrects the exposure of that shot, not available on TH. Plus, there are several third party navigation apps available for Phantom for big properties to automate the capture (big learning curve for this option) , not available for TH. Setup time for the P4, ready to fly can be 1 to 2 min once you get the hang of it. The TH will take much longer, more like 5-8min. And yes, TH is bigger and can't fly as safely in close quarters, as DsAdvanced mentioned. If you want to use prop guards for safety, the TH is a hassle to install those,
check it out. The P4 guards simply and quickly clip in and out, less than a minute.
Yes, P4 has more range, but for real estate you don't need that much range. However you'll definitely get spoiled with the P4 range and want more after you "get high.....from flight".
As for the HEX advantage, I've never heard of a motor or ESC problem with P4 yet, they seem reliable from that aspect. No doubt that having the redundancy is cool to have, and I've seen the TH fly on 5 motors. It works pretty good, but in the real world I don't think the advantage outweighs all the disadvantages.
One huge issue is taking the TH on vacation with you is a major pain when flying airlines. You have to check the drone, you cannot carry it on because it's too big. However you have to remove the LiPo batteries and carry those on the plane (FAA rule). With the P4 you simply carry everything on in a 22X14X9" Phantom backpack, and then during vacation you have a handy backpack to tote the drone around, no hassles. It's so convenient.
There are thousands doing real estate videos with Phantoms. Even a P3A would work good at almost half the cost. The VPS system works very good on P4 as backup to GPS, not available on TH.
When you get your 107 cert, make sure you get commercial drone insurance, and form an LLC or S Corp to protect your personal assets. Those will cost you about $2000/yr (California numbers) just to be in business. Or you can do like others and hope nothing goes wrong.
