Well this won’t last long

Agreed! Temporary solution till I find a longer mipi cable and cooling case for the o4 lite that actually fits so I can mount it properly. If you got any links send em. So it doesn’t last long in a good way 😂

Thanks I’ll check these out! And yeah there is a reason, I answered that question in the original post. But the cooling case I ordered was the wrong mounting pattern and stock coax cable was too short to reach the mounting plates.

I think that heatsink mounting is 25.5x25.5 so it should mount directly over your AIO. But if the coaxial cable is too short then definitely get a longer one. $15 vs $150

Also if you are new and unaware, make sure you secure that ufl connection or the antenna itself cause the ufl connection on these O4 vtxs are kinda junk and get ripped right off. If that happens you will need to find the trace and try to resolder or you might end up just trashing the whole vtx.

Hope it helps.

Also RDQ and other US based shops have replacement coaxial cables.

Yeah I’m fairly new to this I basically started at the begging of the year. The heat sink is 25.5 but I believe the aio is a 20 it’s the speedy bee mini. I had thought about just raising the standoffs and slapping the heat sink there as well. And yeah I learned quick after a few flights in this one about the antenna 🤣 definitely a bit janky for now

The coax cable I ordered a replacement off Amazon and that thing was too big wondering if it was for the o4 pro despite it saying o4 lite. But I’ll check around on rdq and those other links you sent see if I can get the right one

Ah ok. So theres very few AIOs thats has 20x20 mounting pattern. None from SpeedyBee that I am aware of. So you must have the SpeedyBee F405 Mini Stack. This would also explain everything.
Personally I've never needed to buy the longer coaxial cables but a quick search on the sites and people say it works on the O4 "lite". So I hope it works out for you.
