It's easy to push wires through PVC. Here's where I cut the hole. http://donka.net/gallery/view_photo.php?set_albumName=spars &id=DSC04746 The location works out great as it will put the PVC just below the aft edge of the wing access panels. The access panel is not obstructed, and the conduit is right there to pluck wires from for pitot or autopilot. Here's a shot of the PVC in the wing. http://donka.net/gallery/view_photo.php?set_albumName=rightwing &id=DSC04843 other notes: - I put the conduit in place before riveting the skins and it posed no added measure of difficulty while riveting. - I put some blue RTV at all the PVC+Rib intersections to avoid any potential vibration or movement issues. ---------------------------------------- From: Alf Olav Frog Subject: PVC-tube in the wings? Hi builders! Thanks for the inputs on the flap hinge! I'll go for the split-pin metod then! Another one: I'm thinking towards intstalling wires in the wings also, and saw a builder on the net who'd installed a small PVC-tube in the wings. It made room for several wires (landing light, posn light, antenna etc) Anyone else have done this? It seems to me like a good idea?? Specially if I also put a light line in there so I can replace or add thing later. Thoughts anyone??

However, I have 200 hours on my GRT EFIS in my 7A and Im not about to trade it in. It is also impressive. I have it coupled to my 430 and TruTrak Digiflight IIVSG. I love the split screen capability on the GRT. I can keep primary flight data on the left screen and a moving map on the right screen of the GRT EFIS. When I am getting close to my destination, a switch on the panel lets me change the auto-pilot from GPS guidance to EFIS guidance. Consequently, when ATC gives me a different heading and a descent during approach, I have to wake up and turn a knob on the EFIS to a different heading and dial in a minus 500 FPM on the TruTrak. I know it takes all the fun out of hand flying the plane, but it sure makes single-pilot IMC a tad more comfortable. To each his own. It all boils down to what kind of flying you plan to do. If VFR only, save your money and maybe go with the analog 6-pack steam gauges. They still work good. My personal choice is I want to fly IFR when necessary and dont like vacuum pumps. The GRT EFIS works for me. I was convinced by 2 friends who are airline pilots and put it in their RVs.

I too found the lead weight to be too light after installing the pitch trim servo. To correct, I clamped a piece of sheet metal around the weight as a form and used a small propane torch to get the center of the weight molten to within about a 1/4" of the edge, then added lead using large fishing weights. The weight is just a little heavier than necessary and will trim as required after painting. Attached are three pictures comparing the "as is" right elevator weight to the modified right elevator weight.

Hi! Thanks for the inputs regarding PVC-tube in the wings! We're done with the empennage now and both elevators are AFT heavy. On the right one, we adjusted it per plans, but we had to bolt the removed leadpiece back onto the counterweight to get the elevator closer to neutral. On the left one, we didn't do anything to the counterweight. I guess we can solve the problem by adding lead in the forward part of the fiberglass tips before installing them. Have anyone else encountered this? The only reason I can think of is that we maybe put too much tanksealer in the aft part of the stiffners?? (But I don't think we overdid it....)
