Horizon Gyro internal lighting?
I'm going to buy a new R.C. Allen electric horizon gyro to replace the co-pilot's vacuum gyro. I'm trying to decide if I want to get internal lighting or not. I couldn't find anyone that has the un-lit model in stock p/n RCA26BK-6. I need an 8 degree panel tilt and that is a special order from the factory and will take 2 to 3 weeks. The Gyro House has a internally lit unit p/n RCA26BK-9 in stock and will set it to a 8 degree panel tilt for me, but they said that will void the 1 year factory warranty, but they will then warranty it for me for 1 year. The price for getting the one with internal lighting is $150 more than the one that I can order without lighting. Normally I would prefer the internal lighting, except I have UMA EL light bezels installed already. So it comes down to should I pay $150 more and get the internal lit unit which could be shipped out right away or do I wait up to three weeks for an un-lit unit? |

Lighting instruments in this manner produces a far more consistent light, both in terms of color temperature and intensity. In the case of EL lighting, you avoid the need to change bulbs. The inverter may fail, leaving you without lights on the affected instrument(s), but that's why you don't put 12 instruments on one inverter. And, when it does fail, it's a hell of a lot less expensive to replace the inverter vs. remove 6+ instruments and replace the light rings. The Gyro House has a internally lit unit p/n RCA26BK-9 in stock and will set it to a 8 degree panel tilt for me, but they said that will void the 1 year factory warranty, but they will then warranty it for me for 1 year. snip Unless you know for sure that the gyro has been on the shelf for less than a month, I personally wouldn't touch it. Gyros that sit for a surpringly short time go bad, and when they do, the manufacturer won't ship you a new one -- they'll either overhaul that one (with a 1+ week turnaround) or offer to send you a remanufactured (overhauled) unit. Oh, and they won't pay for the labor to R&R it, either. You will have paid for a new gyro and received a overhauled unit. My suggestion - custom order a non-illuminated unit and (if your panel lighting situation demands it) install some ring lighting. I think you'll like the result. -Doug -- -------------------- Doug Vetter, CFIMEIA http://www.dvcfi.com -------------------- |

And I'd reccomend to add the internally lighted one and get your sparky to
wire it up (and a report to give to your "guverment man" if required) so that you have both lighting systems available on seperate switches. Maybe even go to the trouble of having both systems for all the instruments you want on a partial panel! Flicking a switch on final is so much easier than fumbling in your flight bag for that tube of metal that holds four flat batteries! Hope this helps, Peter |
