Re: electric trim tab actuator
so my question is why add the electric trim if you seldom use it? Not making fun of anyone here just wondering if the wiring, weight, switches are worth the effort?

Re: electric trim tab actuator
Good question. Reliability was the biggest reason for me, there are numerous reports of broken Bowden cables so this seemed like the best way to go. I did not weigh the Bowden cable but the electric trim installation is very light and I would be surprised if it weighed more. I also like the idea of having the position display on my panel.smiley wrote:so my question is why add the electric trim if you seldom use it?

Everyone will use their trim differently and some Just Aircraft models may require it more than others. On some other models of aircraft I have flown if you didn't trim there was a lot of weight felt on the controls, so much that it could almost be dangerous not to use the trim.
If I were to build another aircraft I would still go with electric trim.

Since Skyraider and Highwing are both gone now, has anyone found a source for a fiberglass blister faring or is everyone just making their own?

Re: electric trim tab actuator
I looked and looked but didn't find anything I really liked, so I just made my own

Re: electric trim tab actuator
Bringing back an old post. Just wanted to add my pics to the thread. Nothing new here, I too drilled a new smaller hole above the stock one and then cut away the unneeded material. Got the tab filed to final shape. After determining the center position on the servo I attached the clevis and ran the servo with a 9 volt battery to it's limits in each direction without binding. Works great.
It was mentioned earlier in the thread about adding a washer to increase the thickness of the tab. I think since that post the factory went to a thicker tab because mine is exactly the right width to fit the clevis perfectly. It is plenty strong as it is now.
