virtical arm effect prototype.
This is my attempt to try and assess what effect if any do vertical arms have on flight behavior.
So how to build a quad to test this. how to add enough surface area to the arms to cause a noticable effect. without changing the basic form and mass of the craft.
Problems with v arm quads are from what i have seen are weight , arm flex in yaw axis , motor mounting and motor wire routing.
So by building a box section as shown i can move the motors arround to suit and to make vertical arms just tape them up,
Instant vertical arms .
It looks flimsey and by bando bashing standards it is , but if your still reading i think you understand what it is about.
Fly it with the tape on then without . same quad no other variables .
Up date.
Flew it today with the tape on and smashed it to bits.
Well broke an arm or 2.
But before i killed it , it flew great.
Very stable , tracked like nothing else i have flown ,not windy today.
no funny yaw issues and in hard corners no prop wash , its like the fc has jot something to work against and your not dropping into a pile of turburlent air that the quad feels like its climbing out of.
propwash was induceable , but not bad when it did happen. ie dropping in from a loop and just letting it fall into the thrust coloum .
I suppose it felt a bit like i term wound right up but was not hard to push into moves.

Wouldn't it just be easier to drop that extra frame and invert only the forward or rear motors? This way you can have the props at differing offsets for better flow but yet save the extra weight.

I'd love to hear your thoughts after you fly her! Also: I have those same motors, but the branding on them is dys, and they are all clockwise threaded shafts, where did you buy those?

some random ebay dude super cheep, Will post my feelings as to flight dynamics in a bit but i think without a little tuning the arms are going to add more turburlance in cornering than the benifit in straight line stability is worth. But thats only a guess it might corner like a deamon and gluide like balld eagle .
Im also interested how it flies stick style.

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
