Engine or avionics, first?
Is there an advantage to either? Would love to hear arguments from those who have reached this stage in their build.

Engine
I did the engine first. The avionics continue to evolve rapidly, engines, not so much...
|
My vote is engine first—hold off on avionics as long as you can because the avionics industry evolves at a near light speed pace compared to engines which are static for all intents and purposes,
I did avionics first and wish I had held off. I’m happy with my panel but had I waited it would have been even better. |
Definitely engine! The engine has been sitting here for my -8 project for years and Rhonda gives me **** about it every OSH. Life happens when you least expect it. I'm not at all concerned with it getting "out of date" or being "old tech"... Avionics is a whole different thing.

Buy the engine and prop at the last ?Van?s Show Special? that you can wait. Engine is required for cowl fit up.
Decide on the brand of avionics you want, then buy the mounting kits for the autopilot servos, pitot, ADHARS modules and such as these are much easier to do when fitting out the airframe. Buy all the rest of the avionics as the last step. Carl |

I did both at the same time, but engine for sure would be first as mentioned.
A lot of the avionic wiring you can do without the high dollar items also. (lights, antenna's, etc.) |
Decisions
You will be amazed (overwhelmed?) at the number interdependent decisions required FWF. Example fuel, exhaust, cables, low power vs heavy power conductors, cowl, baffle etc. Avionics positioning and wiring much more forgiving in my opinion.

I did it the other way around. And I would still do it this way. I am still happy with my avionics as there is Nothing really new since I bought them 2 years ago?
But I agree to the others that firewall forward is nearly endless with decisions etc.. |
Hi All,
Just a quick note on engines, please be careful of internal corrosion if it is going to be sitting around for a long time. Rob. |
