Are you talking about using a heat gun on dry or wet leather? I hadn't seen that. Does it work like vinyl? I've thought about sewn seams (I've got a machine for upholstery - still learning that too) but am concerned about the multiple thicknesses. Since it's going to be glued down I thought about butt-joint seams but wonder if they will lift or swell/shrink over time. So many questions... Thoughts anyone?

Matching vinyl material if available would be more pliable then leather. If you make pattern out of vinyl a local upholstery shop should be able to sew the material for a custom look but you have to be careful where you put the seam to keep it out of the way.

That's because 'active', in this case, refers to the fact that there's electrically powered circuits (in this case an amplifier) in the antenna to increase it's signal-to-noise ratio. The GPS antennas, however, can be swamped by being placed too near a transmitting antenna. > None of the replies from the various lists indicated much of a > problem either- at least no one identified any specific technical issues. Well, that's because there isn't any. Mounting receiver antennas in a close group and transmitting antennas in a close group usually (never say never) will not have any negative impact. Mixing them close together probably will. Also be aware that some Narco (don't know about others) radios are so poorly shielded that when tuned to some comm freqs will kill the GPS signal. You don't have to transmit ..... just being tuned to the freq will cause the problem.

I think the others who have replied to the effect of 'cut or file for appropriate clearance' are misunderstanding that the F641 is the tunnel cover / seat skin. However, in their defense, it's hard to see how you'd have clearance issues with the F641 without also having clearance issues with the F605 and F606 bulkheads; I definitely had to do some trimming there when I fitted mine. However, that doesn't really address your problem, so I played around with my setup and I think I may have an idea of what is happening; you will have to confirm or deny. If I disconnect the rear pushrod at the transfer bellcrank, I can get close to the same interference (actually, I end up rubbing on the F605 bulkhead first) as the stick approaches the F604 bulkhead (which has been trimmed per the plans). I think this is what you are seeing. However, with the rear pushrod attached (and the elevators in place, etc.) the elevator stops prevent me from moving the stick that far forward and there is no clearance issue. The stick is then approximately 7/16" from the front of F604 on my aircraft. Also, when the elevator is neutral, the upper portion of the stick should be perpendicular to level; if you make the lower portion perpendicular instead, then the stick will be canted too far forward and you may, again, have some clearance issues. The key here is to start at the back; install the elevator, rear pushrod, and then install the stops, making sure you get full movement of the elevator. Then set the elevator to neutral and attach the rear pushrod to the transfer bellcrank, adjusting to make sure the bellcrank is vertical. With the elevator still held in neutral, make up the forward pushrod from transfer bellcrank to stick assembly, making sure the stick is vertical fore/aft with the elevator neutral. At this point, check the motion of the pushrods for clearance. I think you will find it works fine. If that is basically what you have done, then you will need to recheck everything: height and orientation of the transfer bellcrank, height and orientation of the stick assembly mounts, and even the stick assembly parts (in case Van's made an error). Hopefully, this note finds you already with a solution in hand. Patrick Kelley - RV-6A - Still waiting of panel (it's been cut and painted, now in wiring.

Charlie, lemme disagree here. Almost all (never say 'all' or 'never') active antennas are receiver antennas. Such as those with a preamp, like the GPS antennas we're talking about here. Almost all (same caveat here) transmit antennas are passive. There are exceptions to both these categories, but none apply to aviation AFAIK. > Passive antennas are ones such as ADF loop and sense, GPS, XM > radio, Marker Beacon, and stormscope antennas.

All the problems that I have had (3) are from wiring problems that were MY problems. Twice I had a bad connection and one was a wire that had the insulation rub off and intermittently shorted to ground killing the alternator output. B&C troubleshooting guide that they have on their web site was used to find all the problems that I caused. Problems that I caused were spread out over almost 10 years. I made the airplane's first flight in September 1997. B&C alternator and regulator has had no problems in almost 10-years of operation. Gary A.
