"If the I2C port is connected to the flight controller I would be very worried about noise on the battery lines when flying to be coupled into the I2C lines. The I2C lines are not the most secure lines particularly when you start extending their…"
"Can you specify the current and duration for:
Ultra high discharge rate of 100C;
Max Burst discharge Rate: 200C;
These are seriously high currents (130A and 260A) for such a small device. If they have a capacity of 1300mAh they should be able to…"

"My very quick reading of the rules is that a flying robot would not be allowed.

"This is from Tarot:
This is 4S (14.8V) motor, specially designed for FY650~FY690 frames. Able to use with 11" to 13" propellers. In our testing Fy680 Pro, we used this motor, carrying GoPro, Brushless Gimbal and FPV system (all up weight 2.7kg),…"

"There are linear BEC's that use a voltage regulator (and dissipate the energy in heat) for low current from a 3s battery and switching BEC's for higher voltage/current that are very efficient (90%+).
Use a switching BEC sometimes called an SBEC or…"

"Yes. Just make sure the BEC can deliver the current required by the two devices.

"Props balanced? Motor mounting loose?

"Ducted fan motors are very inefficient at producing thrust in the hover. Large props give much better efficiency for a quad. I would steer clear of fans.

"Are you sure about the props and motor rotation being correct for every motor? What size motor/prop are you using?

"Carry a torch - cheaper, more reliable and gets light to where it's wanted.

"Try this paper for more info on controlling monocopters. Would a control surface not be a simpler, more responsive, lower weight way to get the cyclic pitch control?

"I think you did absolutely the right thing going to the police. However I would suspect little will be done unless he can be caught in the act and it can be proven he has committed an offence. Is he on his private land? I would suggest you contact…"
"Looksfairly normal to me. How does the 'copter fly?
