Clothespin on a prop?

[Red 61]

Hey guys,

I've been flying electrics for about a year and a half now -- so I know just enough to be dangerous! :rolleyes:

Anyway, I went to a "Giant Scale Fly In" last weekend, and took some pictures. When I looked at the pictures later, I noticed a closepin on the prop of one of the airplanes!

What does this mean? Why is it there? Please don't let me be ignorant for ever! :o

A fellow RC-er at our field uses a flag whenever he brings more than one plane to the field. The only plane that has no flag on the prop is the one currently selected on his radio. After he switches the radio for the plane he will fly, he moves the flag to the prop of the previously flown (selected on the radio) plane.

In your particular case - I don't know what's the purpose of the pin on the prop.

I would bet that that is his frequency control pin and it is placed on the prop to remind him to get the freq. before he flies. A SMART thing to do !!! ENJOY !!! RED

or maybe he's getting ready to hang it out to dry! :D

Yep -- I think you're right. Looking at the picture again, I realize the plastic marker is being viewed from the side -- if you look closely, you can see it.

Thanks! :)

I agree. In our club we use clothespegs, with our name and channel number marked on them, as frequency pegs, and we put them on the board when we're flying. So, when we're not flying, we take the peg off the board and usually clip it to our Tx antenna to remind us not to switch on. Some people clip them onto their prop instead. It's debateable which is safer; you surely won't start your engine with a peg clipped onto the prop, whereas it's easy to switch on your Tx with the peg still on the antenna. But on the other hand, with the peg on the prop you might still switch on your Tx just to check some throws or reverses, or to do a range check or something.

That's why at competitions they have transmitter pounds, so you don't even have your Tx unless the frequency controller confirms your channel is clear.
