Everyone should be glad we had a smart and sane President president then.

Well you know what say. Heaven for the weather, Hell for the company.

A connector is just that, a connector. https://blog.banggood.com/rhcp-and-lhcp-whats-the-difference-29046.html Depending on your budget these are well liked/reviewed. Pick your polarization (matching) and connector needed for each device...

LOL. Maybe the markings are some sort of Chinese morse code. Well seeing as the connectors are keyed (there is a 3rd sub output too) I'll just pick by position and use the 'X' and 'white' as ground to the speakers. I should end up with relative phase (which is fine), as opposed to absolute...

These are speaker output wires from a little amp board. Can anyone identify what the polarity is? Thanks.

My delta wing built with Dollar Tree foam board. It was just too damn fast, finally smartened up and got a 2S battery for it. It's kinda hard to see but the leading edge of the wing has another layer of foam board on top (~50% coverage) creating a KM airfoil. Went through a lot of props...

Try another USB cable. All cables have the outer power leads connected the same way but not the 2 inner data lines. The official F3 lists these USB drivers. https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

Seems they could simply have measured them for you at least, they must have a caliper. Worth having in your tool box. https://www.banggood.com/150mm-6-inch-LCD-Digital-Electronic-Vernier-Caliper-Gauge-Micrometer-Measuring-Tool-Caliper-Ruler-p-1163536.html?rmmds=search&cur_warehouse=CN

This was a decent drone flic, made by the original Flite Test guy (who seems to be not involved these days,) starring his son. David Windestal (Mr Tricopter) also makes an appearance as does his tricopter.

What put over the top was doing funnels, back and forth, left and right.

Well that looks like a Syma X8 (with their brushed motors) and a different shell, World Tech is not an actual manufacturer. I have no idea why they chose to use such a small battery. Is it a sloppy fit? These are for the X8...

Post a link to your quad. Is it brushless? Are you really pushing it hard? If you go back to the stock battery is everything normal?

No. That said what you might be seeing at times has more to do with the angle and/or brightness of the sun. It's probably not the props you are seeing but their shadows flickering across the lens.

I'd try some rubberized CA, it's supposed to be less brittle. Here's some from your buddies.

Well did ya cap that?

Here ya go.

Those ESCs already have caps. This from Oscar Liang.

That should be fine, the 2200mAh battery is probably too heavy though. Why 7"? Seems like a lot, more length = more resistance.. What gauge wire did you use?

Yup, may as well. The wizard's rubber ducky is not very good, I don't know what your LCD monitor is using. https://blog.banggood.com/rhcp-and-lhcp-whats-the-difference-29046.html These are priced right and folks seem to like them...
