Probably as long as you have a quite good goggle antena set up with high gain patches.

Its to help with wiring for building drones.

If all that was said above is true and its sill not working try turning up startup power on esc configurator

Its a online whoop race you build a track from pvc in your house and submit dvr of you flying it as fast as you can obviously as its a race.

I dont think anyone has done a dirrect side by side test but i belive walksnail has the possibility of acheving longer range with the goggles l with the right drone antenna setup as the goggles have a built in patch (not the best patch). but with goggles x people have acheved over 20km and goggles l will do comprably in a clean rf environment and video quality on walksnail is better than "cheap digital systems".

Try reflashing fc this has worked for me once when i had this issue if it dosnt work try resoldering to a new uart and make sure the rx and tx are bound the rx led should be solid.

Walksnail has integrated headtracking dji dosnt you can always add a module for head tracking to the top of your goggles I bleive but am not sure because maybe you need AV in for that but i dont think so i think you plug it in to your radio. About the same price DJI pricier long term because air units are more expensive. I hear a lot of fixed wing people like walksnail. Take that as you will. 

What i did was got the lite radio 2 se and then gave it away to get a friend into the hobby and upgraded to to tx15 max when it was in budget for me to buy. Have been happy with what i did. 

Hard to find pilots near us our age isn't it.

Also check if in beta flight you have the number of magnets on the motor bell set correctly as i had severe jitters on a whoop build because i had it set wrong and assume it could cause more severe issues aswell.

I wouldnt say so but it depends what you value. If you want to just get straight in the air then sure go for it but tou wont have the best experience. Id say for that money just buy a radiomaster pocket and liftoff simulator or whatever you see fits your fly style.

For dji o4 you adjust settings through goggles when bound to air unit.

I dont belive the betaflight vtx tab affects anything with the DJI o4

Idk if this might be your issue but I fly walksnail and i suspect that some elements arnt compatible with hd osd with is what o4 pro uses, and its just a osd element compatibility problem for hd vtx's in betaflight. I have no clue how to fix this and just use the elements that work and deal with it. I find most of them worck though just not the ones that require telem from VTX/Goggles for some reason for me and some other stand out ones.

Personaly if i were to build a o4 freestyle drone id go with the o4 x shape mario 5 over the manta as it is more popular / more talked about and has good things said about it.

Both easy to build in frames I belive but the manta will give you more space if that matters.

I just wanted to clarify from my previous response.
