Default RE: Pull/pull and CF pushrod questions

CB,

I have several posts in he SD thread. Page 69 post 1772 shows most of the install you are asking about. It sounds like you will be building a SD very similar to mine. I used the tensioning system on the pull-pull set up bild 3 in post 2 above linked for you. I used SWB manufacturing control arms on all my servos except the throttle. I used Ball links on the control arms and the heavy duty Dubro clevis sets on the control surfaces. I will try and look up the Dubro parts I used for the control horns, they arte the heavy duty ones. Also note I crossed the pull pull cables and I have a picture of this back on page 68 post number 1692. Also shown on that post number is the tensioning system Bild 3 is talking about, a good picture of it.

The carbon fiber pushrods are very simple to make and install. Again, look at some of the pictures of what I did in the SD thread. That thread full of great data for the SD. Right now I am working on my choke set up. When I balanced the plane I only had to add several ounces to get the balance point at the CG, which is important. Hopefully maiden flight sometime in May when the weather gets better. Any questions ask, I will try and help you if I can. My SD looks real nice, but like you will find the plane has it share of issues. Nothing too bad though.
