Default E-Flight 540 BP gear fix

Okay we all can admit the stock gear would even bend on a rubber band plane. I sat and looked at the plane thinking of ways to fix my gear to something better. Using what I had laying around I came up with a few ideas. Here is one of them. The other I have no made yet.

I had a carbon fiber rod laying around so I cut it to length and cut a small slot in it. I then cut off the stock gear right at the wheel pants leaving about 1/4 left. I grinded it down to the size of the diameter of the carbon rod. I then slid the 1/4 portion into the rod and JB welded it and slide down some heat shrink over it.

On the fuse I drilled out two holes size of the carbon rods in an X pattern. Doing this one gear is slightly ahead of the other but didnt matter to me. I just needed a gear. If I want to make both equal it would be easy just notch on each carbon rods and let both sit flush and glue. After the holes w.as drilled i slide the rod into the fuse on both sides and glued in. I could of done it more nicely if i wanted but this done in a hurry. Here are some pics of how i did it

so just an idea to try over stock gear. I think paper clips would be stronger than the stock gear.

Thanks for the suggestion on the gear fix. I have also been trying to think of a way to put different gear on mine - possiby just a wire gear. Since the gear is so soft, one problem I have had is banging the prop on landings - which has led to breaking the motor mount stick several times. The only possible problem I see with your fix is that you still have the soft aluminum at the ends. While the carbon rods will certainly be strong, the aluminum piece at the end may still want to bend.

The ends are very solid even with the aluminum ends on it. You would have to feel it to see what I mean. Those ends are not bending unless I grab them with pliers and bend them myself. The thing I will have to see is how it holds up since there is no give really. I dont land hard at all mostly float it in or catch it. The problem I had was the gear bending backwards when I landed in the grass. I think it will do fine for now. If anything breaks I have another EDGE in the box ready to go.

I was going to use wire also but didnt have what I needed to try it out. I was going to copy the gear off the Aeroworks profile they have. That looks simple and easy, just to bad E-Flight didnt come up with that gear.

Update on the gear. Okay this set up is not a good idea. Pulling gear off.

I flew last nite and had a ball with the plane. When it came time to land I set it down in the front yard. My grass is cut short but this plane is so small the wheels catch the grass and it comes to a complete stop right away. When I landed one wheel touched before the other and the plane yanked around real quick. Just a small twitch but it was enough to snap the bottom of my fuse. This plane cant take sudden movements like this at all. My gear did not have any give and it was the reason for this. If it had of been a wire gear the gear would of gave and it would of been okay.

So going to scrap the idea. Oh well on to the next gear. This time I got the stuff to make the wire gear and going to move on to that one next and see how it goes. I am determined to come up with something other than the stock gear.
