RE: Fliton Element 170 ARF build
Now I installed the rudder horns. I had some short Mk horns sitting here, so I used them. The hole in the rudder was larger than any bolt I wanted to put in (weight saving mode) so I put in the Mk's. I did this by finding a bolt that fits the horns, cutting it to length.. Then I found a carbon rod that was the perfect size to fit the bolt in (inside diameter), the I drilled out the hard point to the (outside diameter) carbon rod. I then ca'd the carbon rod in. Then installed the bolt (again with ca) and put the horns on.
