Smart ESCs included with E-Flite planes are not compatible with the MrRCSound systems but there is an easy workaround for the issue. The Smart ESC uses different signals than a typical ESC and will cause erratic behavior with MrRCSound sound systems. Both the V4.1 and the ASPIRE are affected. Throttle response does not work properly and in some cases the startup sound will repeat over and over. You may not get any sound at all. These issues appear when using a Y servo wire to split the throttle signal between the sound card and the receiver. This work around requires...

Heng Long has recently announced that they will be changing their business model to support the growing global demand for their products. In the past, Heng Long would produce 20+ different tank models in small batches during each production run. While this allowed them to offer a wide variety of models in a short period of time, this did not allow them to achieve certain economies of scale related to mass production. In their new business model, Heng Long will be producing large batches of only four tank models during each production run, and they plan to have approximately four...

I signed up for Back in Stock Notify, but I didn’t get an email when the product came back in stock. Why did this happen? This is a common question and here’s why it happens. When a product is back in stock, our notification system compares the number of units that arrived to the number of people on the Back in Stock list. Everyone on the Back in Stock list gets an email if we get more units of stock than the number of customers on the waiting list. If we receive fewer units than the number of people on...

First, let’s define what flutter is why it’s important what it can do and how we can prevent it from happening. Flutter is instability due to an interaction between aerodynamic, inertial, and elastic forces it’s known as aeroelasticity. Incidentally, it’s not restricted to aircraft. The original Tacoma Bridge spanning the Puget Sound in Washington collapsed on 7th November 1940 as a result of aeroelastic flutter. All it took was 42MPH wind to make it happen. Control surface flutter on aircraft was discovered in the early days of aviation and became a particular problem during the first World War as aircraft...

It’s been my experience over the years one of the least understood things about flight and in particular with R/C models is the stall. What is it, why does it happen and when does it happen and more importantly how can we prevent it from happening. A stall occurs when the weight of the aircraft can no longer be supported by the lift being generated by the wing ( helicopter beats the air into submission) and this can and will occur in many attitudes and not just at reduced power in straight and level flight. One of the most important...
