Large Scale RC Airplane

Large Scale RC Airplane

In this article we are going to look at giant scale RC airplanes. These large scale RC airplanes are more often than not war birds, both fighter and bomber variants, believe me seeing something like a B17 flying around is truly impressive. These giant scale RC airplanes are generally categorized by their weight. This is because when an RC aircraft reaches a certain weight, in this case over 44lb (20kg) models are subject to an inspection by the Large Model Association on behalf of the CAA in the UK and the IMAA in the US.

This series of inspections are designed to ensure the safety of the public, by imposing certain standards in the construction of the airframe and integrity of its control systems including double redundant elevator control, twin batteries with automatic switching etc. These airplanes usually have wingspans of greater than 85 inches and look superb in flight.

These large scale airplanes are normally powered by petrol engines up to and sometimes beyond 100cc. Many users are now exclusively using 2.4GHz Radio control equipment; all servos must be of the metal gear type and things like control clevis and horns need to be beefed up. This is where weight starts to play its role as these airplanes need stronger heavier kit for durability, they also need stronger heavier and sprung Oleos to absorb landing shocks, and so weight can increase exponentially. These large scale RC airplanes are not particularly difficult to fly and sometimes they can be easier due to their increased stability, this is especially true in gusty weather.

Many might say that this is an awful lot of hassle when if you keep the weight below 44lb you are relatively free of rules and regulation, but I urge you to go to a meeting of these large war birds you may just become hooked.
