When it comes to radio controlled flying one of the most important things in all the hobby is safety, and when I mean safety I do not just mean your own, I mean other peoples as well.
If you look at the hazards you face when it comes to radio controlled flying you have to say starting up your plane is right at the top of the list. The percentage of people who cut their fingers, slice their fingers or even lose a finger through not starting up their plane correctly is quiet high.
But there is not just the start-up of the plane that's a problem, there's a problem of the plane moving forward on its own once it's started.
So what do we have to stop these hazards causing us injury? Well in today's model aircraft scene we have electric starters which are powered by a twelve volt battery, of the more basic method is the chicken stick which is basically a stick about 12 "in length with a rubber sheath at the end to grip the propeller.
Now for a restraint to secure your model when you start it up they're a number of options. You can buy a single ground anchor (or a Y anchor) as its know which you secure into the grass then your aircraft stabilizer sits in the top of the Y securing it when you start-up your model.
One of the best designs that I found was the adjustable long restraint, its one metre in length and has two adjustable loops with trident clips one on each loop and two fixed loops in the other end. It also has a sliding D ring for once you have tightened up your restraint at the back of your model aircraft you simply slide the D ring up to the stabilizer and this stops the restraint from coming off the stabiliser.
The loops at the other end are for securing to a ground anchor or attaching to a towing ball of a vehicle.
The good thing about this restraint is that it can be used both at a Tarmac runway and at a grass field. The other advantage of this type of restraint is that if you have a larger scale model around 120 size and above you can adjust the clips on the adjustable end so you can attach it around the fuselage for added security.
Overall be safe at the field when you fly but most important "have fun".
