At that price it is a bitter pill to swallow. The VIFLY is better than a normal buzzer by far and popular apparently.

It would be good to know if there are any plans to have this stocked with some of the well know UK retailers such as HobbyRC or Quadcopters.co.uk.

CurryKitten on YouTube seems to be the king of lost model gadget/buzzer reviews as he's reviewed pretty much all of the other ones on the market, so I'm hoping he will also get one of these in for review as well because it would form a good unbiased direct comparison review against the others he's done. Maybe the manufacturer/distributor of these could offer him one for free to review.

Yes, some UK dealers will stock our units like Unmannedtech. Yes, CurryKitten will do the review for us.

(25-Jul-2018, 09:28 PM)SnowLeopardFPV Wrote: Yes, that's a fair comment  At least one of the reviewers made comment that the HellGate would sometimes get confused about what state it was in if you plug/unplug/plug/unplug the main XT60 LiPo battery too quickly so a dedicated disarm button solves that issue, however that instead seems to introduce the problem you stated if you have a tight build.

One other thing is that the HellGate will beep for up to 3 days but the VIFLY is specified as having a working time of up to 6 hours. I have a feeling that once the 30 second pre-alarm period expires, the VIFLY probably just beeps continuously at full volume until the battery runs out which is probably what the 6 hour limit is. The HellGate on the other had has intelligence built in to reduce its beeping frequency as time goes on which will reduce its ongoing power consumption.

Specs:
Size(L x W x H):23x13x16 mm
Weight: 4 grams
Volume: Up to 105 dB
Working Time: Up to 6 hours

I'm quite interested in these but the OP doesn't appear to have returned back here to answer any questions so I've asked them over on RCGroups to see if I get a reply on there.

>>For the button design, it makes disarm operation much easier, no need to plug-in-out the battery and the force may affect the life of battery. This is why we design the button. And the buzzer is tiny and we think it is not very difficult to find a place to put as most of drones are carbon fiber design and lots of exposured parts. Anyway, our design team see this concern and we are thinking of finding a way that can disarm the buzzer through the controller. 

For the beeping time, it will beep for up to 6 hours. Yes, it beeps continuously at full volume unitl the battery runs out. We think the first several hours is the best timing to find your quad back, we must ensure the volume is big enough. If you can't find your quad in 6 hours, is it still possible to get it back after 3 days?

Acutally someone tested hellbuzzer volume is only 73dB (10cm distance), VIFLY Finder can be 106dB. I think volume is very important when finding the lost quad in the grass or trees. How do you guys think of this?

Thanks for responding. That's great news. I'll look forward to the review by CurryKitten

Yes, that is probably a fair point. I did always have a slight concern that if you were unable to retrieve your lost quad for whatever reason after finding it (maybe a little too high up in a tree) and needed to return another day, that the continued beeping could potentially alert others to the presence of your expensive quad over a longer period of time and allow someone else to retrieve (steal) it before you were able to come back for it. There is probably a really small probability of that actually happening in the real world but the possibility does exist. I guess there are pros and cons to the beeping operation of both products.

Yes, the louder the better in my opinion. I guess the reason for the HellGate being quieter is because of the much smaller buzzer but I think I would prefer a louder volume over a smaller buzzer. Also, in one of CurryKitten's reviews he was having trouble hearing and distinguishing one of the other lost drone buzzers over the sound of the birds so I think a distinctive beeping pattern is also a key requirement. I see that the VIFLY just beeps constantly which may not be the best solution. Maybe for a future version it would be a better idea to change it to a distinctive pattern of beeps instead (the HellGate uses bursts of 4 beeps at a time for example). Just my opinion and a possible improvement suggestion  I guess we'll see what the reviewers also have to say.

Can you please also comment on the charging of the built-in LiPo battery. Does it use some kind of intelligent charging like the HellGate? We all know how easy it is to damage a LiPo if it's left in a fully charged state for too long or if it drops below the minimum safe charge voltage, so how does the VIFLY mitigate those risks to its built-in LiPo?

No need to worry about this, it will stop charging when it is almost full. Our team has considered this when designing.

>>>Good suggestion. Will let our design team know and see how we can improve it. 

To fix the concern that the disarmed button may not be touched easily if we put the buzzer inside the quad, VIFLY Finder final version added another option to disarm the buzzer. Now two options to disarm VIFLY Finder:

Option 1: Disarm with button: Disconnect main battery, hold disarm button on VIFLY Finder for 1-5 seconds then release.

Option 2: Disarm with main battery: Disconnect main battery, then connect main battery for 3-6 seconds and disconnect it again.

It will beep 3 times when disarmed successfully.

CurryKitten posted his video review of the VIFLY Finder yesterday. I see that Wayne makes the same comment as I did previously about it being a better option if the buzzer made some kind of distinctive pattern sound rather than just a constant single periodic beep. Also, don't forget Oscar included the VIFLY in his written built-in battery powered buzzer comparison review HERE as well 

Sorry 'Kitten' but the tag line of your vid is "Never lose YOU drone again"! I am willing to overlook this little mistake as I have spent so many years in South Africa where they commonly don't bother to add the r or 're to the end of "you". They also often fail to add are before "you" as well.

ie. 
"What are you doing?"
"I'm flying my quadcopter, can you see it?"
"Ja, you're  flying over there"

The way they twist their vowels can be hilarious too, such as using the sound of U instead of I, and  I instead of E...
ie. (- haha   ) 
"Would you like to take your drInks outside one our dEck"!!
"I wasn't aware I had brought any drunks with me, and If I had, I'm not sure I'd subject them to being outside on your, err...!"

The Vifly Finder racing drone buzzer can adapt to RC drone and flight controller. Here is an honest review by Australian racer Grumpy Trev.

Looks like V2 is now out...typically just a couple of weeks after I bought one of the V1.2 versions 

I want to not like it as I don't want to mount something else on the quad, but I do like it....and I like that it is LOUD.....

hello! I know this is a super old thread, but I found it searching for "amp draw" on my hellgate buzzer.
I'm worried that my camera, TBS GPS M8, and buzzer will be pulling more than 2 amps total from my T-motor F7 FC.
do I have anything to worry about?

I would not worry too much. Camera amp draw is typically about 200mA. GPS 50-10mA. And buzzer about 100mA.
