Default Keeping a prop attached to the plane

What ways do you use to keep your prop attached to your prop saver? I lost my 4th prop today and I've had enough. I have tried o-rings and orthodontics rubber bands and they don't work well. Am I missing something? I use an AXI 2212/20 with an APC 8x4E. And don't tell me not to use a prop saver. My plane doesn't have landing gear and I'm not going to make landing gear for it.

You have any tips?

With no landing gear why not go with a folding prop

if you point me to where I can buy a 8x4E APC folding prop then I will definitely do that.

Hatty -

I've seen it recommended that prop savers not be used with power systems over about 100 W. Beyond that, many people move on to collet-type prop adapters.

It may be that rubber bands and o-rings can't take as much power as you are asking of them.

Here's a trick than may help. Don't go to full throttle fast. The torque will most often snap the O-ring or most other "prop saver" retainers.

Check out Hobby Lobby, they have both Graupner and Aeronout folders, APC not in that market.

I had this problem, and if there is room to put a second o-ring on it will possibly solve the problem. My first electric plane had a Rimfire outrunner (22-1000) on it, and my first flight the prop flew off. After a rough landing, I popped 2 o-rings on, and have'nt had a problem since. Good luck!

Landing Products (APC) do make an 8x4 folder: http://www.apcprop.com/cgi-bin/store...c=6a&product=+
