Hello people.

Considerable drone noob here from EU, need to gather info on his current build. What you can see in the pic. are the current parts that I have and I have two serious questions I am still trying to understand:

1. I got 2307 motors and all local shops have 22.2V batteries, what mAh I should be aiming for, as to what has been suggested online is 1050 - 1300mAh but what would be better for just flying without any tricks or racing

I know that the motors i selected are with freestyle in mind but that won't be done before I pass at least 40h mark on SIM.

and 2. I also want to add a GPS for retrieval if connection is lost, are there any type of specific GPS's that I should look into or do all of them do the same thing, as if that's the case, I know that walksnail has that covered too (haven't checked that much on those yet, preferred to ask someone knowledgeable)

OH, and actually 3. the SpeedyBee Nano ELRS-2.4G has only one antenna, how important it is to have an ERLS RX that have 2 antennas, is the difference noticeable and needed? (seen bunch of people having one in front and one in back of the drone)

Also, please let me know if you think there might be something incompatible. I think the Avatar HD Pro camera might be too thick for the TBS camera mounts, so I might come up with a 3D print part to incorporate that, as I think the camera is 2.0mm thick when the stands are 1.8mm thick.

  1. A 6S 5" build should be using batteries between 1000-1500mAh, your preference.

  2. If you really want a GPS, look for an M10 model, those are the current generation with the best performance

  3. Receivers with two antennas are better, but how much better and whether or not it's worth it depends on you, your environment, and a lot of other factors. Most people fly with a single antenna receiver and have no issues.

that was a quick response, thanks! I presume that the only main difference in the mAh is the weight of the battery then? As from what I saw most are about 200+ g. Usually the total weight for a 5" shouldn't go over 700g or so? I am of course accounting for a GoPro that might be another 160-200g, so I guess the battery would be the most heavy

An average 5" build is going to be 400-500g "dry" (no battery or HD camera), +200g battery, +100-150g for HD cam

#

As long as it's under 1000g AUW (all up weight), then I would call it normal

#

You can swap smaller batteries to save a little weight when carrying an HD cam, but IME the difference is marginal at best and I don't think it's worth it

#

FWIW I run 1100-1300mah on my 5" builds

#

Exact weight doesn't matter too much tbh

dire pine
#

gotcha, that makes sense, as by what I read I was a bit worried that the weight might be too heavy but this gives me a some relief on the topic.

#

thanks Daedalus for the wise knowledge, I'll be sure to post some pics for a check-up when the assembly will begin!

Make sure you don't buy all the Walksnail stuff separately

#

buying the kit saves you money

#

and same for WS, you don't really need dual antennas and it makes it harder to mount

dire pine
#

I already got the dual antenna KIT, so saved money on that I guess but yeah, I saw that there are not a lot of options for 3d prints for dual antennas, GPS and a RX in one but I might have not searched hard enough.

#

luckily I have some people known that could help me make one too but that will be more time consuming

#

If you do do the GPS thing

#

Keep it as far away as possible from the Walksnail vtx

dire pine
#

oh, is that some signal thing not willing to work together? Like, how far minimum, as the vtx and gps would be 1.5mm away from one another approx. I'd like to understand what's the reason of it

#

GPS antennas are very sensitive to interference, so much that even having some wires laying on top of them can prevent them from working properly

#

I would say you want at least 5cm of separation between the GPS and the VTX+antennas

#

There are 3D printable mounts that mount the GPS on top of the battery by attaching it to the battery strap. Since most people mount the VTX antennas out the back, that's about as far away as you can get unless you mount the GPS out the front (not recommended)

tired crown
#

at least the v1's do

dire pine
#

noted. will look into options to create enough separation between the two

Helloo again. So, I am ordering some of the last tools for the assembly and a question arose regarding the Walksnail Avatar HD Googles - I know that they have a built-in receiver for the walksnail VTX but my question is - should I look into acquiring additional antennas to attach for the googles, for increased quality/connection. I also have found it difficult to find specific info regarding the difference between digital and analogue googles antennas (if it's even a thing Harold ), would I need to look for specific one's for my wlksnail HD Pro kit (dual antenna ver.)?

tired crown
#

There's no such thing as a digital or analog antenna

#

The goggles X currently are a mix receiver, so you can have either omnidirectional antennas or directional antennas

#

I can recommend TrueRC X²-air MK2

dire pine
#

Noted. Also, as for the polarization, as the antennas for VTX are LHCP, i should be looking for the same polarization on googles, correct? Also, I would assume I would be getting a pair of TrueRC's, one for receiving and one for sending the signal, yes?

tired crown
#

You always want to match polarization yeah

#

the ports on the goggles x are rp-sma

#

you'd be both receiving and transmitting on one of them
