Some of the others also blew fuses. But, in several other situations, the fuse/circuit breaker never blew, but the switch showed signs of overheating. Bob, and others, are hypothesizing that the strobe system cycles cause repeated inrush currents that don't blow the fuse, but which produce overheating of the switch. The overheating sometimes results in the switch shorting out which does blow the fuse. All of the failed switches so far are Carling 700 series switches. A more robust switch seems to be the short term fix.

A few days ago I received a post card from the NOAA informing me the Satellite Coverage for 121.5 MHz ELT's will end on February 1, 2009. It further indicates in order to receive Satellite coverage I would need to be operating on 406 MHz. Does this mean there will be a mandatory change of ELT device in order to maintain my AW? I realize it would be near useless to continue with the one I got if I don't change it. The question is more about what the requirements are going to be. I also noticed just a week or two ago where someone was purchasing a new unit at something like $895. This is about twice what I remember paying for my current ELT that works perfectly. What are others doing here? I really hate this! That is my fuel budget for several months.

That is my fuel budget for several months. ================================== I have the older ACK E-01 ELT and their new compliant ELT E-04 that uses the same panel mounted control and will fit in the same tray is going to be out in a few weeks. The retrofit kit is going for MSRP of $560. Maybe ACS will discount it slightly so perhaps it's worth calling them to see once it is released. I will probably budget mine for Q1CY09. My suspicion is that once their new design and qualification investment is recaptured they will deal on these, but it could be a few years.

Our ELTs are still perfectly legal, we just need to be aware that satellites will no longer be listening on 121.5. If our ELT is triggered, responses will be based on either aircraft monitoring 121.5 (nearly all commercial aircraft do so) or monitoring by ground stations. The satellite-based ELTs are obviously superior to the 121.5 only units, and each pilot must decide how important it is to have the latest ELT technology. But the FAA has left that decision to us. Canadian pilots MUST make the change to the 406 ELT.

I better star > saving for the $800 or so... WRONG!!!!!!!!! I have no intent to get a 406 MHz ELT at this time. I have an unreliable 121.5 MHz ELT. I have a 406 MHz PLB (GPS enabled) I intend to get an APRS system. The later two offer better "services" that the 121.5 MHz ELT in my opinion.

Dear Listers, Today marks the completion of my RV-8 Tail including all of the fiberglassing and tip installation. I had asked the List a while back about filling the backs of the tips on the Vert/Horz Stabs and got some great feedback. I used some hard foam and built a "dam" and glassed the inside then rapped the outside with tape and filled with resin/flockedcotton and then sanded it down to the right size. Worked great and the next time I could do the whole thing in a couple of days. Rather than glassing over the whole end of the surface onto the fiberglass tips, I opted to just mount using screws and platenuts and only glassed AL-to-tip on the Elevator counterbalances where necessary. They came out very nice I think with minimal fuss and muss. Since the Rudder bottom and Fin Top had to be removable for access to wiring, I decided that I wanted everything to look the same and so I used the screws and platenuts throughout. Really didn't add that much weight and allows for tip removal down the road without paint damage. The mount for the VOR/GS/LOC antenna on the Vert Stab came out very nice I think and is very solid. I definitely learned a lot about fiberglassing in the last couple of weeks as well as gel-coating. Lots of pictures attached.
