tcal780 Posted February 28 Report Share Posted February 28 My son and I just started the journey of updating the panel on my 1970 C! I'm super excited to do this with him as he has been working for the last 18 months at my local airport as an apprentice to gain his A&P cert. We're both going to learn a lot. His boss, the local IA, has agreed to oversee, and sign off on the project. Going in: Dual G5's GNC255A GMA345 GI106A (backup-only for Nav2) JPI900 Cies fuel senders Aera 760 Going Out: Vac system Century HSI Intercom Original Engine gauges KI214 KX175B The KX165, the STEC30 and the GNX375 will stay. The pics will give you all an idea of where the panel was, where it's at, and where it's headed. This is the progress we made just this past weekend. Best, Tcal 7 Quote Link to comment Share on other sites More sharing options...

tcal780 Posted March 9 Author Report Share Posted March 9 I finished 95% of the old panel cleanup. The remaining wiring seen in the photo will stay. A couple questions for the group: First, panel mounting. Are there "standard" mounting brackets and avionics rails available for a new panel like this or will I need to have them fabricated? The avionics guy said vibration isolators are not needed anymore, citing Garmin avionics often don't work well with them. Is this the case? Second, some advice on lighting. I am considering a combination of LED bezel ring lights for the 5 round instruments and an LED strip light on the underside of the glareshield for an overall flood. I'd also like to have the toggle switches or switch labels illuminated. The original throttle quadrant/flap labels and compass are also illuminated with incandescent bulbs. Can these be converted to LED? Ideally, I would like the avionics and the instrument ring lights to be on one dimmer and the remaining flood/panel lights to be on a second. What would you recommend? Thanks! Quote Link to comment Share on other sites More sharing options...
PT20J Posted March 10 Report Share Posted March 10 I believe the GI 106A is has been replaced by the GI 106B. Are you purchasing a used GI 106A or did you find a new one on the shelf somewhere? Quote Link to comment Share on other sites More sharing options...
Aerodon Posted March 10 Report Share Posted March 10 Some suggestions: MaxDim Duo for panel and glareshield lights. Nulites (incandescent work just fine, I think they make LED too but check that they are compatible with your dimmer) KI206 or 209 for the KX165 to save a bit of money. I think in the long run you will regret not doing 2 x GNC255's. MD93 clock / OAT / USB C etc. GI-275 engine gauge for space saving and symmetry. Small vertical stack of circuit breakers like later model Mooney's on a separate panel. It really helps to finish the power and grounds inn the airplane and have a quick connect like Mooney does on later models. Aerodon Quote Link to comment Share on other sites More sharing options...
Aerodon Posted March 10 Report Share Posted March 10 Here's a rough start based on my M20K panel. I think your turn co-ordinator needs to be mounted vertically, or at least recalibrated for an 8 degree tilt to get a flat panel all the way across. Or you can try doing a vertical panel all the way across? I think a tilted panel will reduce the height of useable space in the radio stack because of interference?

tcal780 Posted March 10 Author Report Share Posted March 10 Thanks for the suggestions Don. I am planning to use the maxdim duo (or two single max dimmers). I prefer to not mix incandescent and LED, so I'm not sure what to do with the throttle quadrant lights. This is (was) a vertical panel but the existing brackets and vertical rack rails are not suitable for reuse. I'll will need a new plan for those. This will be a two piece panel with the breakers all on the far right. Tcal Quote Link to comment Share on other sites More sharing options...
