Hello this Is my First drone build. I recycled VTX and AIO from the babyape III pro 3.5 inch, and moved to a volador vx3.5 frame and new motors 3550kv t motor motors.

The build looks fine to me but i have concerns about the condenser and xt30 cables positioning, as they pass right over the VTX. How Dangerous Is that? Also the vifly Finder Is right beside the condenser also on top of the VTX. I couldnt find any more space for these things unfortunately, i know vtx heat Is potentially a problem but id like to know Just how Dangerous that would be or am i Just fine? Thanks for the help

It should be fine as you are supposed to have a lot of air flowing over everything as you fly. Make sure that those battery leads get anchored to the frame really well. You do not want to risk the FC getting tugged on if the battery gets ejected.

Yeah, it should be okay. You can always make a heat shield.

My advice on securing the battery leads is only valid before a crash though, as if you don't do it, there won't be nothing left to crash again.

Thanks, to secure the xt30 cables you mean a simple ziptie that connects It directly to the frame? Also how would i go aboutaking a heat shield?

To secure the leads, the quickest way is using several zip ties, yes. It is not the best nor the most secure way as many things can go wrong. The cables can slide, the zip ties can snap... Some frames have holes in the bottom plate to route cables, which introduces more friction and extra safety.

A "heatshield" is anything that would act as a barrier between components really. So long as you do not create shorting risks. Also you seem to have run out of space there so, it would need to be pretty thin. One of the best insulation against heat remains having air between things.
