Of course, managing the fulcrum location can also change the magnitude of the Output Force as well because it changes the distance ratio of both sides. So there is an opportunity to control the amount of Force we need while using the same Input Force. The former is ‘fractional’, the latter ‘decimal’, and as a rule decimal and fractional tyre sizes that look the same are not. For Work and Energy to be equal on both sides, the upward Force applied on the Output side must be twice the amount on the Input side because of the difference in the distance.

Weight Comparison 1: The StinGR unit all-up with prop mounting hardware and connectors is 15.8% lighter than the Q100 all-up.Since late 2018, I've been involved with the R&D of an electric power gear reduction unit that can deliver comparable power of a 120cc gas engine, and potentially greater. The answer to this question is where Force comes in. Force represents mass in motion and is the product of mass times acceleration. So, for Force to be a value greater than zero, it must have motion. With this in mind, let's think about what is happening when we apply energy to a common tool, like a lever. Levers help us move masses easier than if we tried to move the mass without it. Some objects that just won't budge when we try to lift them ourselves, seem easy to move when we apply the use of this simple tool. In effect, they give us seemingly superhuman strength when we need it. But how does this lever really do this if I'm not gaining energy from someone? There is no industry-wide convention for tubeless tyre fitment and satisfactory results are mostly likely using parts made for use together such as Mavic’s UTS (Universal Tubeless System) tyres and rims. Nevertheless, tubeless-compatible tyres are generally available in the standard 29"/700C/622mmISO, 27.5"/650B/585mmISO and 26"/559mmISO formats. It is inadvisable to use non-tubeless tyres without an inner tube as there is a risk of tyre blow-off. Tubular tyres

This thread's intent is to illustrate and explain the benefits that a StinGR gear reduction unit provides the electric RC aviation community. All tyres are marked with a pressure. Sometimes this is an absolute maximum that nobody should need to exceed, or sometimes only a recommended maximum that may be exceeded by heavier riders (such as tandemists). Pre-machined – saving you labour time and cost, plus it removes the hidden cost of machine downtime.

We stopped supporting Internet Explorer in April 2021.

Here is a performance table with general expectations of the different StinGR combinations we now provide, and here is what each column represents: The ideal relationship between tyre and rim section is about 1.8 to 1, but any tyre from 1.4 to 2.2 times should fit – always provided that the bead diameters correspond. By understanding the concept of mechanical advantage using a simple lever, we can now see how Force extended over distance can increase.
