Maybe it will be if that thing ever decodes to puff up? Looks cool though.

Hmmm... Wonder if I need camo tape now!

The power distribution board on my HTFPV just shorted

I plugged my battery in for the first time and I see a spark fly out from the frame and I smell something burning. Freaked, quickly unplugged the battery, and took the frame apart to expose the power distro board and it looks like it shorted in the connection between the positive battery wire and the board. The board seems to be visibly singed there. What're the odds that the rest of the components are toast?

Electricty follows the least path of resistance. The majority of your juice was flowing through the short, not the peripheral electronics. Shorts are hard on batteries...even if for just a split second. Everything else that isn't directly between the battery and power distribution board should be fine.

i have this frame and it is flying flawlessly because of the 2 alu bars that i had tie wrapped to the frame.

if i remove this 2 alu bars, the quad is yawing randomly to the right or to the left and the whole frame is vibrating.

i don't know if i did something wrong...

what do you think?

The HT FPV frame is not what you have pictured. Yours looks like the VC-450 frame. On my VC-450, I have never had a vibration issue or any other odd flying characteristic. The VC-450 is like one of the best, most stable frames out there.

Make sure all your bolts are tight and that you don't have any hairline cracks somewhere.

Good to know. Battery's fine, tested it. Knowing how volatile lipos are though I was afraid I'd have an explosive situation on my hands.

Took another look at the board in the daylight. It looks like the copper connection to the positive battery wire and the rest of the board "popped". Is this something that I can fix with a bit of solder?

I would figure out why it happened in the first place. It would take a lot of current to do this. Something shorted and the copper acted like a fuse.

Also, those battery lead solders look poor, as well as the one at the bottom right.

My guess would be a poor solder between the XT60 plug and positive wire. I'm going to open the patient up for exploratory surgery, but before I scrub in, is that an issue I can fix by soldering the popped connection back together or would it require a replacement distro board?

I wouldn't risk it. It's such a cheap part to replace..

Oh I ordered a replacement last night. I was just curious.

My guess would be you had a solder blob that shorted the positive and negative wire pads. As for repairs, unsolder the positive lead from the current pad and solder it to one of the empty + pads on the inner part of the board. If the original copper pad has lifted from the board I'd cut it out and remove it so it doesn't run the possibility of shorting against another negative pad. So is it fixable, yes, by relocating the wire to a different + pad.

Also, something does quite look right here. Looks like solder went under the paint and got really close, this may have arced.
