Optipower Backup Guard

[Mark_T]

Good point. I run at 6V, which means the UltraGuard would run at 5.5V. A buddy at the field experienced the same issue with his BUG, so I don't think it's a unique issue.

Just tested the Ultra Guard on a 550 with 3x610, 1x650 servos. ESC/BEC is Kontronik Jive set for 5.6V.

After disconnecting the Jive the Ultra Guard took over instantly and no amount of stick stirring could persuade it to drop below 5V and certainly no chance of a brown-out.

Looking good so far I'd say

Just got mine fitted. It looks like a cracking, well built device.

My only niggle, a constructive criticism if you will, is that the leads to LED are very thin and delicate. In future releases, some shrink wrap would be a great benefit.

I tend to agree, also a pity the LED isn't socketed at both ends really. I know it is a space thing as well, not just cost, but it would have made things a little more flexible and made it easier to add the LED later if required.

Yeah I bought the LED version thinking it was removable as chances are, I'll not use it. I've just mounted mine, got it all neat then realised I can't reach the button lol. Doh!

really exited , ordered 4 , the first one should be coming this weekend , will be selling my scorp BUG soon

Just fitted mine to my logo 480 and plugged a pack in to charge it up

Same reason I never liked the Hitec 7 channel receivers, having important features at both ends of a device limit the ideal locations.

You need to reach the button every time you disconnect the main power and you'll want to reach the JST connector when you want to completely disconnect the battery.

Minor imperfections though compared to the utility of the device.

One thing that's really getting on my baps, if you turn the motor when you have shut it down it comes back to life, so you have to plug the main power back in and go through the shutdown process again, not shure if its a bug as it just seems to be pulsing a small charge ?

I wish I didn't have the LED version now.
As said above it would be better with a plug at either end, the soldering on mine isn't good and it's only a matter of time before the small black wire comes off!

Lots of interesting ideas and comments, firstly this is a SAFETY device its not designed as a 3D flying power supply, its designed to let you know you have an issue get down and land. Secondly we are aware that the device would benefit from a plug both ends V2 will have this as standard, a couple of months away I ma afraid. Thirdly the device is designed to be ON, you power up its on so you do need to switch off, this is designed so you do not have to remember to switch ON!!! Fourthly, we will modify firmware so it will switch off after a period of time of voltage inactivity, i.e. if no voltage change for say 30-mins it will switch off, again V2 sometime off. We are also addressing the dim display if over 7.3V system voltage in V2. If you press the switch off for more tahn 3 secs it will go to discharge mode and this does alternate the LED's on the board and the device will warm up, this is normal and ony to be used if you intend not to use the device foe more than a month or so.

This is a safety device not a 3D flying power system and must viewed as such, 7A continuous and 10A peak if LED flashes you have a problem, idle off and land!

[OPTIANDY]

Mark, we designed it such that it will work with all ESC's and deliver a trouble free power supply as an emergency system, its not designed to be a full on 3D power supply just take over as required and indicate that you need to land pronto. It's good for 7A continuous and 10A peak so under most conditions will work fine. It will operate from 4.8v to 8.2v and anywhere in between. So far in testing with the worlds best pilots its been fine on all systems, Nick Maxwell to Dunkan Bossion and many top guys between these. Rest assured we tested it at the hihgest levels!

What about it coming back on from one click of the motor, it seems like its picking up the very small voltage generated by the motor and arming at that voltage ?

I will check mine when I receive it and if the same, then would apply some hot glue around the solder point and would be good to go.

Yes works on BEC systems even the more complicated ones like Kosmic. The device does not set straight away it waits and samples the voltage then after about 5-secs it sets this is to allow time for the Kontronik device to boot as they boot at 5V then step up to the set voltage you have programmed. The device charges and balances in flight using the BEC/RX Pack/Life pack as it's power source if it needs to, when charged (max charge is 8.2v) it stops. Lots of data on the website guys. The field test pilots used different systems to test it these were Nick Maxwell, Dunkan Bossion, Steve Gerrard, Mathias Fischer and Dave Fisher. They use a selection of ESC and some use BEC's some don't. Tested on Kontronik, Scorpion, Castle and other all work fine. Voltage sampling is super fast and the device will drop in as required and drop out if not required. We call this an Intelligent Backup Device for these very reasons. It's also truly plug and play. Voltage input range is 5.3v to 8.3v re charging and balancing 4.8v input min operational voltage. In the event of an in flight reboot of the ESC usually fatal, the device holds the voltage during the reset and keeps things going, it does not reset itself in these circumstances. Any further questions please ask but you can be rest assured we tried to cover everything and what we did not will get included in future revisions as required. Demand is stunning for these devices which is great news and we as always have a policy of continuous development.

Experience RC have them on order and will get stocks shortly watch their website. Demand has caught us out a bit and it was supposed to be announced after the Toy Fair which was the official launch unfortunately one of the magazine released the advert a month early and that rather upset the production planning and stocking.
