Default Gaui X7 - Link of tail problem (My solution)

Hi Guys,

Below images with my slight modification to improve the movement of the linking of the tail.
Problem was with the guides move in flight, because they be very smooth.

The solution was quite simple, I used thermo-retractable tabs, as the images below:

Guides without thermo-retractable:



Guides with thermo-retractable:





Guides in place:



Video of the test with modified tabs:

Could you please explain exactly what you mean by moving?
Rod rattling in guides??? The guide runner locations on the rod look very close together to me.

You are gluing the metal tube bits to the rod no???? The way the pic looks to me is that iou are using the heatshrink to hold the metal tube in the guides and the rod loose to slide through them.

The tubes are to be glued to the rod and then the complete assembly together slides through the guides. Just don't over tighten the guides to restrict movement.

Apologises if i'm looking at this wrong

Edit. Just saw the video.The way you have it will eat the carbon rod and cause the loss of tail control.
As in the instructions, glue the metal tubes to the carbon rod in the correct locations. The carbon rod and metal tubes should be one piece and move together


Remove the heat shrink(thermo-retractable). it is not needed and will just bind the assembly

Default plastic on plastic

That doesn't seem like a very good idea to me I could see that rubber or plastic against plastic catching.

I think that my ideia is better than use CA.
For me my idea, clean service and safe

This is my opnion.

Default ca

Ca Doesn't ever seem to hold well between plastic and metals what you should really use is a two part epoxy.

My opinion is that you run the risk of the rod flexing and binding on the ends of the metal tube. It will happen in flight, not on the bench. Best case, you're going to simply wear out the rod, worst case you'll get binding in flight and wag.

I've seen someone do this with a T700N and he is cutting chunks out of the rod in flight because of the flex and also getting debris in the tube which will cause faster wear.

The metal tubes get CAd to the rod and slide in the plastic guides. The reason there is metal there is to minimize wear and have a small, slick sliding surface. By having the rod slide in the metal rubes you've made a wide friction area.

I don't think this is a good idea. Does the heat shrink covered sleeve slide inside the plastic holders? If so, that is def not a good idea. The reason the sleeves are CA'd to the carbon rod is to allow the polished sleeve to slide in the guide, ever so smoothly.

Rubber doesn't slide very well.

EDIT, I see now. I take it back, but what you ARE doing could eat away at the carbon, slowly. I've done this too (without the heat shrink), but haven't been able to keep mine crash-free long enough to witness the long term effect of this setup.

I just cover the metal tube with Black-Heat-Shrink tubing

For me it was much more reliable than using CA or Epoxy
