Peter Seddon commented on Echo G's blog post The Dumb-Battery Era is Over
"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…"

Peter Seddon commented on sarah lee's blog post Tattu R-Line 1300mAh 100C HV LiPo Review: Extra Boost for your Racing Drone
"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…"

Peter Seddon replied to Arunava Pal's discussion Question about battery performance
"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…"

Peter Seddon replied to Pride Smith's discussion Electric Jet Fan Quadcopter Build
"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.

Peter Seddon commented on Joe Renteria's blog post Monocopter Concept
"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?

Peter Seddon replied to benbojangles's discussion Help! I'm being shot at!
"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…"

Peter Seddon replied to Chris Wilson's discussion Flight mode behaviour changes when camera and gimbal fitted
"You don't say how the behaviour changes and under what flying conditions. 

Depending on the weight of the gimbal relative to the rest of the airframe the performance could change.

Peter Seddon commented on lee winterson's blog post Drone ban coming soon in the UK?
"I think your title is a little hysterical. PSPO's are local orders that could ban or limit flying in specified public places where it is deemed to be a public nuisance. There is a consultation prior to the introduction of an order which ensures that…"
