getting into fpv

[miky94]

Hi,
I'm getting into fpv and I have some questions, I only flew 100% self-built unstable monstrous drones so I'm not worried about flying fpv difficulty, also I'm not interested in freestyle racing but instead in cinematic cruising.
I like the Flywoo Explorer LR 4", but because budget is a priority, the analog version.
now questions are:
1 ) I have a Turnigy Evolution PRO transmitter, is it compatible?
2 ) instead of $100 goggles I'd buy the Eachine ROTG02, is it ok flying slowly?
3 ) I have seen someone fly it with the Insta360 Go, do you think the HERO5 Session is flyable too?
Thanks

I have... only 3 questions
Ok number 1 it should be mounting his FlySky receiver
Number 3 maybe mounting a lighter battery
What about number 2? Signal is transmitted via radio and the latency due to the analog to digital conversion should be low, not optimal but flyable I think, I could upgrade antennas and use the smartphone in a goggles case or use a computer

 

[Dugdog47]

Haha yeah my attempt at being funny lol.

As to your question, I've only ever used the 5.8 tx and fatshark goggles so IDK about what you say there. Try it and tell us how it goes.

Take a look here at 09:23

maybe with your goggles experience you can tell me how does latency seem to you, should not be far from fpv digital systems

 

[Dugdog47]

Ah yes the eachine 5.8 reciever I actually have one of those. Yes if you could get some cheap vr goggles that hold a phone it would probably work just fine. You probably won't even notice any latency.

this is good news, with $25 plus maybe $10 for antennas upgrade I could start fpv, having ready to share dvr on the smartphone

One thing about using a phone for FPV though, what if you get a call right in the middle of your flight?

 

[miky94]

Well maybe it just rings in background or I could use one without sim

 

[miky94]

which inexpensive antennas would you reccomend me? banggood says ROTG02 has diversity but I think it has only one receiver anyway upgrading two antennas instead of one is better right?
in the explorer specs I read ESC Continuous current: 13A, so what would be a safe discharge rate?

If someone calls while flying, we are no longer friends... Why are they calling anyway i only accept calls from telemarketing .

really though can use do not disturb option on your phone while flying and i think will avoid the interruption. Still even some cheap goggles are nice to block most if not all the sun glare too though.

Guys I need your help...
I finally received the Explorer but with the HM600 VTX instead of the VTX625 and should be good because it is more powerful (600mW vs 450mW) but I can't connect the antenna, am I stupid or is the connector wrong?

[wafflejock]

The wire and connector appear to match to me I know on some of these tiny antennae connectors you have to put a crazy amount of force onto them to get them to snap down, to help you might want to use needle nose pliers or other tool (small flathead for example) to push down on the back of the antenna connector when trying to get it to snap on. Plus side once on they usually hold pretty good. Also do double check the exact connector name there is a bucket full of options with MMC or MMCX and RP vs normal all sorts of potential variations/permutations unfortunately.

 

[miky94]

I did it with a screwdriver, the HM600 VTX is better than the VTX625? and what other receiver do you recommend me with the Turnigy Evolution PRO?

 

[miky94]

After first difficult attempts in and out home I finally I went to an open space and I flew 3 times the battery in angle mode not fpv, a bit difficult to see how it is oriented when far away and if because of this I make a mistake sometimes I overdo with the throttle and then it is difficult to regain control.
Anyway it survived all the crashes.
When I pitch/roll/yaw sometimes even without compensating with the throttle it gains elevation, maybe because of the wind.
Now what do you recommend me to do first, to start fpv or to start with horizon and then acro? Should I start with a simulator? Is there a free version of liftoff?
Also I'm looking for receiver and maybe goggles,
receiver must be:
- Flysky
- reliable
- long range
- small
goggles must be:
- cheap
- portable
- dvr
What do you suggest?
Also the VTX 600mW is better than the 450mW right?
Thank you

Hiya, sounds like a pretty familiar experience for anyone who has taught themselves line of sight flying so congratulations

There are a few flight test videos that go through some exercises you can do for learning to fly line of sight with more control. I would suggest you completely skip on horizon mode it just teaches bad habits really and does things that are not entirely predictable. Regarding the quad not staying "locked in hover" this is normal it takes a lot of getting good at throttle control to compensate without thinking much for the quad falling etc. to keep things at a more solid hover. The wind can have some effect blowing things around but most likely just a matter of practice to get the throttle control locked in better and understanding the small delay in response and time it takes for motors to ramp up to speed to get really tight control.

Appears lift-off doesn't do the demo version anymore but can get it on Steam and can return anything on Steam I think within 24hrs so long as you don't put more than like 2hrs of gametime in (even beyond that can contact them and let them know why it took longer if debugging stuff and will give you the refund). I'd recommend grab velocidrone as well pretty sure you need to sign up to get the download link but can try 1 level and 1 quad in there for free then can pay to unlock if you like that more than lift-off (probably just best to get velocidrone ahead of time since the lift-off install/refund time is limited). I think both are worth having though as a person who flies a lot and can learn in sims and have some fun (multiple games means more levels and variety).

Also strongly recommend any sort of sim before just jumping into Acro/FPV. Acro is way easier when in FPV than when flying LOS since orientation in Acro is basically as though you are sitting pilot seat and the quad stays in same orientation unless you give it input. From LOS it's real hard to fly acro but from FPV perspective it can feel pretty natural after a couple of hours in a sim. More time in the sim the easier it will be to fly in real life really and the more you can learn to do "power loops" and "aileron rolls" etc. without risking crashing your real life quad.

Oh also regarding VTX and goggles, I think any goggles with diversity will be better than any without (in my personal experience) and having good antenna and good connection between your antenna and VTX and antenna and receiver the better off things will be. The higher power transmission is really only needed when going for much further range or trying to penetrate some thick vegetation but when flying clear line of sight high in the air the extra transmission power won't really matter as much.

 

[miky94]

Thank you I'll try exercises and velocidrone, then I think next steps will be fpv angle and then fpv acro.
From your experience on average how many batteries will it take between these steps?
Anyway good to have a more powerful VTX.
The EV100 seems to be a good for beginners, unfortunately they don't have dvr, whay about the radio receiver?

 

[miky94]

I could also start wth this one https://www.amazon.it/Visore-virtuale-occhiali-smartphone-android/dp/B06XY2W6S9

You could use something like that along with your existing phone as the display and then something like this:

Amazon.com

Keep in mind I haven't used that actual product and can't tell you if it's any good or how it compares to others but basically this will receive the 5.8GHz analog video signal and pipe it into your phone somehow. How much latency this will introduce is hard to say. The "total latency" I'd say is the time it takes from when you move a stick to the time you see the reaction in the video feed to your face. So there is the time it takes for the TX in your hand to get the signal to the RX on the quad then time it takes for the FC to respond to the signals from the RX then the time it takes for the camera to capture and encode/transmit the analog video signal + whatever time it takes for this RX to decode the video signal + digitize it + for your phone to display it. All of these things are individually probably pretty fast, like 25ms or so for TX to get signal to RX and probably in milli to nano range for the FC to respond but then ESCs/motors also take some time to respond and physically change speed (again probably milliseconds to second range) but add it all up and you can get some noticeable latency that can make it difficult to fly (as well as you could if it were more real time)

Personally started with something like these eachine:

Eachine is always coming out with some budget friendly entry level stuff that can be somewhat hit or miss though too so shop around and look for reviews. I had one with terrible receiver in it but didn't know any better then a buddy let me try his (also eachine just slightly newer) and they were much better, now I just burn money on goggles so have HDOs and DJI
