yes, i use a phantom to do exactly that . anything similar(china clone) will do though. it is somewhat a baseline requirement. you need the picture to be clear(from vibration), you need live feed(to see where the camera is pointing) and angle adjustment(you don't want the craft to move around while inspecting).
yeah, if you set the "roof surveying" requirement out of the equation, a lot of cheaper possibility opens up.
I just want to spot any roof tile not in place or broken, not trying to analyse small gaps.
If I do take out the roof survey out of the requirement, what options do I have open?
I'm having issue with my bugs 8. For a couple of nights I tried to fly, it only lasted less than a minute before I get low battery warning. Actually the quad loosing altitude before sending low battery warning. For each tries, battery is fully charge. What is going on?

Does your battery bloated? It sounds like the battery loosing its 'punch' power. How old your bug? How many cycle you've put on your battery? Did you put the battery into 'Storage' charge mode when not in use?

The battery is not bloated. 6 months. I play almost every night recently. Earlier this week, raining two night straight & I unable to play (the battery was recharged). During this time I didn't put it to storage mode.
Today, just a couple hours ago, I tried to fly again after a couple of recharge & discharge, it still only fly less than a minute but when I connect to my rc truck, it can do a couple of laps before it slow down. Right now it is discharged & I'm planning to re-charge again tonight using my balanced charger. I'll update again after another attempt tonight. I don't have extra xt30 plugs to test with another battery to rule out the quad. I have two batteries with deans plug & two batteries with EC2/EC3 plugs.

Sound like the battery can no longer holding its 'punchy' power by the sounds of that, the discharge rate is gone.

Is this acceptable for testing the battery? It is wet outside & I don't want get my truck dirty.
The motor is running at max speed for 7 minutes without slowing down. It only started slowing down at around 8 minutes. I'm afraid the controller in the quad might have been faulty.

You can't test/measure the lipo efficiency consumption like that because both R/C truck and quadcopter have different current consumption per-second. R/C truck consume low ampere rating per-throttle while quadcopter consume higher ampere rating. Usually i use Amp meter like this one to measure Amp consumption below:
Photos:
Voltage might likely drop from 12v to 9v during throttle on quad which trigger short runtime and causes it to land, that mean your lipo voltage sagging under load. When no throttle applied it will return fro 9V back to 12v again = Lipo sagging.

Thanks for that explanation. I'm going to try with my other batteries. These other batteries, I did put them to storage charge mode before I put them away. I just need to recycle the XT30 plug from the stock battery.

Back in business! Bigger capacity too, 2000mah & 2500mah that I used with syma quad before but capacity may have depleted some because it doesn't last long as it used to.

Hey guys, whats's up? Anyone still flying around here? Just sharing update about R/C flying and some drone stuff activity on my side. Busy teaching students some R/C tricks and building flying model projects. Btw here some scenery around the class and some good meal in between next to R/C bistro.

Current project. Will fly with FVT LittleBee 30a ESCs, Holybro Kakute V2 flight controller, 9 inch propellers, Eachine Okkan video camera & TX526 VTX.
Having issues with the servo-operated tilt rotor tail assembly - seems to be a universal Achilles heel for tricopters. Quanum Trifecta tricopter airframes are selling for US$5 at Hobbyking at the moment - I'm going to challenge myself to build that little bugger for under RM250 total...lol...

Nice to see Tricopter configuration is where while majority goes on quads . Make sure have enough BEC amps to supply the tail servo as pushing the tail torque is quite high during rotor spin. How much runtime expected we're looking at on this tricopter? My buddy's DIY woody tricopter with 700kv motor, GWS 10x6 prop, 20A esc and 3300mah 3s gets about 16 minutes.

The tilt tail rotor assembly fits the spline on a TowerPro MG90s, although I'm waiting to see if the spline of a digital MG90D matches up. As for the amps, do you know how much is needed? All I know is that these servos run on 5V, which means I can hook it up to the 5V out on the PDB of FC while running the signal wire to the FC. The Kakute V2 FC's 5V out will supply 1.5A max, not sure about the amp headroom on the PDB's 5V out. I also have a bunch of 5V switching regulators/buck converters that will output 3A.
Planning to fly it with the stash of 3S 2200mAh lipos that I already own. No idea how much flight time I'll get out of it with these Racerstar BR2313 960kv motors.

I have MG90/90D, they are very amp hungry. Stand alone 2A~3A BEC will definately helps tricopter but depends how much your rotor counter force pull/thrust. I use these a lot for as servo tail rotor on my ALIGN 250 heli.

My FPV ES Drifter going cloud surfing again this week after observe much stable weather, no more rain or typhoon. Just some heavy but stable wind under its wings.
