<div style="margin: 0in 0in 0pt"><font color="#000080">Min2,</font></div><div style="margin: 0in 0in 0pt"><font color="#000080"> I was surprised that you needed “up” mixed in with flaps. I have a “Wild Stik” maybe you have seen the video I posted a couple pages back. Anyway, I play with the flaps on that thing quite a bit. Anyway, it takes a ton of down to keep the thing from standing on its tail with the flaps down. But, it has flaps and not flaperons.</font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><font color="#000080">I also have “airbrakes” or “crow set up on the thing. That is were the flaps go down and both ailerons go up. <span style="color: #339966">(I did not notice Bob had already described "Crow" till after I wrote this).</span> That takes a ton of down as well.
By the way, that plane does not need flaps in any way, shape, or form but they are sure fun to play with. Talking about STOL....This thing will do it.</font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><font color="#000080">Bob,</font></div><div style="margin: 0in 0in 0pt"><font color="#000080"> I have heard about the tip stalling tendencies using flaperons before. It makes perfectly good sense to me that they could cause a problem. You can also run out of servo travel and/or bind stuff up if you are not carefull with the set-up. I figured I would play with them some on this Extra in order to get some first hand experience. Need I say that I will start with a little altitude before I ever put it on the ground that way. </font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><font color="#000080">More on my Extra’s progress.....</font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><font color="#000080">I relocated my rudder servo with the intent of shifting weight more to the rear. This will also help a little with getting the wing bolts in and out. Earlier in this thread someone else did this as well. </font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><font color="#000080">I fashioned the servo tray from some 1/8” plywood. A piece of balsa is used to couple it with the stock tray to the rear and a 3/16 X 1/4 balsa with balsa triangle stock makes the rail for the front.</font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><font color="#000080">With the elevator servos in, I was able to get a measurement for the centerlines of the linkages. Since the stab is not glued to the plane it’s a lot easier to mark and drill and keep the holes strait. As the picture shows I used masking tape to mark the center and working from center I marked the location of the holes for the “control horns”</font></div>
