Update 1-14-18: Two of the arms in this assembly are matte finish carbon fiber and the rest of the parts are gloss. 


FPV racing craft manufacturers typically advertise their craft as having a certain thrust to weight ratio. The reality is the actual value they claim isn't accurate. Historically craft power ratings come from peak motor thrust (as tested on a thrust test stand) divided by craft AUW (all up weight). With this method no value for inefficiency has been accounted for! These losses of thrust can actually be quite high and are directly tied to frame geometry. A more accurate way to describe the real world thrust/weight capability of a FPV racer is NET thrust to weight ratio. This is the actual thrust produced by the machine AFTER losses. An analogy to this is automobile horsepower ratings. Auto manufacturers claim a certain horsepower rating, but this rating isn't really accurate. Its not telling the whole story. The horsepower rating auto makers advertise is the power produced at the motor's crankshaft. Referred to as "crank horsepower". After power from the motor is transferred through the drive train and out to the wheels there are a certain percentage of losses that reduce this power number. The true value of power/weight in an automobile can be determined by placing the car on a dynamometer (aka dyno). This will tell you how much power the car is making after losses. So we determine the NET power/weight value using this method. The exact same thing applies to FPV racing quads. As thrust from the propellers moves through the frame there is a certain amount of losses. These inefficiencies of the airflow hitting the various surfaces of the frame result in a reduction of power. Specifically, any flat surface (perpendicular to thrust vector) causes a loss of thrust produced over that area. in other words typical 'flat plate frames' produce little to no thrust in the areas of the frame that sit under the props.  

This is why the Stigg is different! This craft has very low thrust losses due to frame geometry. Meaning more of the overall thrust produced by the motor is retained yielding a high NET thrust/weight ratio. How did we achieve this? Is it magic and sorcery? No, its just simple physics. We made a departure from all the standard 'flat plate frame' designs and rotated the carbon fiber plates that sit directly under the propellers by 90 degrees. This drastically reduces the surface area of material under the props minimizing total system thrust losses. How does the Stigg compare to an equivalent 'flat plate' 200mm quad running 5" props? To give you an idea lets concentrate on one arm. Every frame must have arms that run from the center hub (where the majority of the electronics reside) out to the motors. Standard 'flat plate frames' designed for racing use an arm width of around 20mm x some length. This is 20mm worth of material stopping airflow and cancelling out thrust generated in this area. By comparison, the arms of the Stigg are 2.5mm wide because the arm is sitting perpendicular to thrust. There is a outer brace that runs the perimeter of the craft. These brace parts are 3mm thick. Two braces reside next to each arm. This gives a total cross sectional area under the prop of 2.5mm + 3mm + 3mm = 8.5mm. So the Stigg arm is 8.5mm wide compared to other frames with a 20mm wide arm. That is a huge increase in thrust efficiency! Meaning more net thrust available to propel the Stigg faster than anything else on the track.

The four circles in the first graphic below represent the total thrust area of the Stigg's props. The blue areas are portions of frame geometry that act as obstructions to propeller airflow. The yellow areas are locations where air flow passes through the frame unobstructed. When we set out to design the Stigg our goal was to reduce the blue areas as much as possible, which reduced thrust losses and increased thrust efficiency. The second graphic represents a typical 'flat plate' type X frame with 20mm wide arms. Below are the actual values of 'arm' surface area obstructing airflow in either case. The area occupied by the motor has been removed from both calculations since no thrust is being created here. 

The Stigg 195 arm obstruction surface area (total) = 2,267 mm^2

'Standard frame' arm obstruction surface area (total) = 4,000 mm^2

    Note: All shipping prices listed on our site are for shipping and handling costs associated with shipping your order. 

    Domestic Shipping within the USA

    By default we ship via USPS (United States Postal Service) to anywhere in the United States. But, if you are interested in a faster option such as DHL email us at and we can give you instructions on how to get expedited shipping. If you want expedited shipping be sure to email us prior to checking out with your order. We will arrange a shipping quote for you and then give you instructions on how to include this shipping option at checkout. Our USPS shipping option usually takes 2 to 4 days to reach anywhere in the USA. By default this shipping option will NOT require a signature. If you want us to specify signature required please let us know prior to placing your order. 

    USPS Insurance 

    USPS shipping includes $50 insurance by default. If you require more please let us know prior to placing your order. PLEASE NOTE: We will not be held liable in the event your package or package contents are lost, damaged, or stolen during shipping. When your package leaves our shop and is placed in the hands of the shipping service it is out of our hands. We have no control of what happens to your package after it leaves our doors. Shipping insurance it available to protect you in the event something happens to your package during delivery. We will not reimburse you for lost, damaged, or stolen items. That is what shipping insurance is for. If you would like to add shipping insurance to cover the value of your purchase email us at for more info. 

    International Shipping 

    We can ship to almost anywhere in the world! Available international shipping options are using United States Postal Service (USPS) or DHL. USPS shipping will be per the flat rate option. This is $28 and can take 6-10 days to reach your country. From here your country postal service will deliver your package and can add additional delivery time. Usually USPS tracking ends once the package reaches your country. Our second shipping option is using DHL. This is considered a premium option and is very fast. Customer service with DHL is the best in the shipping business. Typically DHL only takes 2-3 days to delivery to most locations throughout the world. DHL international shipping always comes with tracking. While this is a more expensive option it is much better than USPS.
