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.

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit. Here are some of the improvements: Higher quality EMAX ECO 2306 1700kv motors Foxeer's top-of-the-line Falkor mini camera Eachine 25mw-1000mw Leaf VTX with microphone Tools This..
