Anyone in the UK looking for some video goggles? I just saw this in the latest CPC catalogue and it looks like a pretty decent deal.

Anyone here in the UK has a "spare" CEOSD that they want to sell?

Is there any other place other than BEVRC that sells these? where/who do they come from originally does anyone know?

I wear specs and to complicate it a bit more, they're varifocal.
My take on goggles using a ski mask designed for spectacle wearers.
http://www.fpvuk.org/forum/index.php?topic=635.0

Also, my ground station with 8" LCD TV + Archos 400 + SD/CF solid state recorder (records through static, so no 'blue screen').
Difficult to see the LCD's in daylight without a shroud.
Not shown is the tripod for mounting the VRx.

I got the LCD TV on eBay as the ones without built in FreeView go for next to nowt (15 for mine), runs on 12V and only consumes 1 amp when powered up. Has AV input too.

I wear specs as longsighted (+2.50), but don't need them to wear goggles!! Just means have to launch / land with gogs on - or wear contacts.

Say you have a lipo pack that is more than capable of delivering the max ampage of your motor or ESC, like a 35C discharge rate 2000mAh batery, so 2x35=70A right...

And your motor specs say max current 40A. Then what is the problem of getting a ESC of 40A? will you stress you ESC? will you not use your motor to its full potential?

Say you have that same motor, max current 40A and you get a 60A ESC. What can be the problems then? frying your motor because the ESC provides too much?

I still dont quite know how this all works but I would like to.

Also, what happens to a 50A current sensor on a OSD if you put 60A through it?

Thanks

ps. just as an example I bought some time ago the grayson V3 motor, came with a 20A ESC. later because I thought the ESC could be giving me some issues i swapped the ESC for a 25A one. don't know if it was the ESC or the reving of the motor while stationary ( no air flow while range check) but I smoked it. Later tried it and it worked fine (on the old ESC tho)

anyway... just a few thoughts I've been having

ps2. what about connecting that same 60A ESC to a smaller 30A motor...

Bandarra,

A 40A motor can only 'pull' upto it's maximum rating, even if you had a 90A ESC feeding it, you wouldn't hurt the motor under normal conditions.
You always need to use an ESC of more than the motor's max rating, in your example, a motor of max 40A needs to be supplied by an ESC of more than 40A - eg, 50A or 60A would be fine.

Nigel.

thanks! that is good news!

by the way... given your explanation I don't have that problem anymore (because I plan on buying a CEOSD [50A current sensor] and my motor will only pull up to 40A) but out of curiosity what do you think would happen to a current sensor if you go over? should be built fail safe and only display its maximum and not fry... lol not sure if that what they do

As with any semiconductor, if you go over it's rated limits, it will almost certainly go pop.

I thought most current sensors being supplied now were rated at 100A, in this case, bigger = better (for a healthy safety margin).

Yeah I worked out that there's 800 replacement cost, what with the zeph itself, gopro and all the gear.
Mike, I'm curious, what other vids do you want to make.
Monster I've uploaded a vid with a password to Vimeo.
Ha well i wondered if your usual launch place is within hitting distance of Ryde Pier... But you can do it first then maybe I'll follow you the next time

got a 180deg digital servo from FPVHobby. the Servo is ok (nearly 180deg - maybe I need a radio with more endpoint adjustment) and arrived within a week. Adnan is on RCG and seems a pretty decent sort of fellow
