    Like the restraining is being done by holding the tailplane against a couple of foam clad posts.

    Surely a couple of short lengths of rebar, pushed into the ground, with foam pipe insulation round them, would do the job.

    The only difference being, this device also prevents the plane from moving backwards when you apply pressure with the starter. It saves you having to reach over the prop if you're alone.

    I can see a use for it, but as you say, two pieces of round bar and some pipe lagging would hold the tail fine, and for the front, a length of 3" X 2" with 2 X 9" nails driven through it and pushed into the ground would work for behind the wheels to stop it moving backward,

    To be honest, I think it's a bit overkill, and like you, I'd just cobble something together in a few minutes that would work fine, but I guess it does look a bit better than rebar

    Oh yeah.
    Hadn't thought about it moving backwards as I'm not used to having to use a starter.
    Not on aircraft anyway as I only fly electric.
    Used to run IC boats, but didn't have starter problems there.

    Like you say, a bit of 'four-b-two' and some long nails.

    Nothing wrong with rebar. Some people make sculptures out of it

    It would. and many various methods of poles and wire with pegs can be used.
    The point with this kit is that the plane is secured from moving forward and back without somebody standing over the tail. Once the engine is started you can move around to the rear of the prop do any adjusting required knowing no matter what you do ie you accidentally hit the throtle to full the plane will remain secured to the ground. When you're ready to fly the safty switch can be moved to green the rear pedel pressed and the restraints fall to the floor and your plane can taxi out without having to lift it clear of any make shift poles or persons legs.
    Have a look on the airopult website for video demo

    Yes, I like the pedal release.

    I guess some people may feel this is expensive, but after you've cut half your arm off, you might think otherwise.

    Think Saftey: Don't be mained, Be Restrained

    Lets be plain speaking here.
    This device doesn't stop you cutting half your arm off, any more than some 4x2 and bits of rebar.
    With them you can walk around the back if you want to, and you don't need anyone standing in front of the tail.
    But with this device, or the 'home made' variety, you can still cut your arm, or even slice your fingers right off - if your not careful.

    I wish the purveyor of this device the best of luck.
    It's a good idea, and a worthwhile business venture.
    But for me, personally, I could make something similar, including the pedal release, for much less money.

    While we are on the subject of the pedal release, that alone I think could be a risk factor.
    It could get activated, by accident, when someone was in front of the prop.
    Also, when released, the aircraft is free to move on its own.
    At least when you have to positively hold the tail fin and lift it over the restraints, you have a firm grip on the aircraft yourself.

    Like all tools, you have to know its limitations and work within them.

    Yes, there is no silver bullet to guarantee there won't be accidents, but I like this thing, and €150 is not that much. I just spent €125 on 5 servos.

    Lugging it around may be more of an issue.

    You are right about lugging it around, but once it's setup it's worth it.

    The issue about the pedal release being hit by acident is small as you can jump up and down on the pedal but untill you kick in the safty it won't let go.
    I've had a 100cc edge on a high tick over pressed the pedal and nothing happend until the safty was released.
    most planes rear end overhangs the pedal so somebody walking past can't hit it.

    It's a good system. Would we be still be discussing bits of 2x4 a year later?
