Default CPI Install RV-10

My aircraft has just turned 2 years old and we have flown just over 300hrs.

While there are a few other threads about CPI install,I thought I would share my experience as it goes together.

http://www.sdsefi.com/cpi.htm
When Ross first released the CPI (Coil Pack Ignition )and the early adopters starter showing their results,I was hooked . At last there was a true maintenance free ignition system that once installed and configured would do exactly what it was supposed to do without further adjusting or maintenance.
No moving parts at all.
As a LOP WOT flyer that sometimes use mogas,having the feature to easily adjust my timing by just one switch,sealed the deal for me.

The kit arrived and I started the install.

Crank Angle Sensor.
I decided to order the Dual Crank Sensor as I plan to in the future install the second ignition. You can install the sensor without removing the prop,but I wanted to "Armour Plate "all the wiring that was near the flywheel and this made the task way easier.
I used some 3/8" 5052 tubing left over from my fuel system to run the wires and clamp in position .





Coil Mount
While Ross has provided many options for mounting the coils,I had always wanted to use the space on top of the engine frame.With the coils mounted up high and the R/H Mag now removed,I can see my oil filter from the side for the first time. It should make the next oil change a lot easier.
I made a new coil mount bracket from some scrap 1/4" T6 alloy that I had.
It was a fun day in the shed with my new drill press and trusty jig saw.
A couple of adel clamps and it was rock solid mount for my new coil packs.





Weight
I weighed all components as I removed them and added in all the new parts.
The CPI system is 500 grams lighter than the Mag I removed.

Spark Plug Wires.
The Wires are the high quality MSD 8.5mm Super Conducter wires with the stainless clip on leads. These are cut to size as you install them.I sourced some cable clamps from the local hot rod shop to tidy up the install





That's all for now as I am about to start my journey to Oshkosh where I hope to meet some more of you and put a face to the names that are on these forums .

Any comments or observations are most welcome

Ashley, looking good.

I am getting close to being done with a dual CPI install myself, good to see how others are doing things.

What are you doing for ignition switch/s and starter switch?

Hi Mike,
From the beginning I had installed 2 X toggle switchs and a push button start.
So , I'll just be re- wiring one of my toggle switchs.

I am at the airport now and will spend the next 30 odd hours travelling to Chicago via Vancouver .

Finally on the way to Oshkosh !

Cheers

Looks great Ashley. Sure feels good to get those magnetos out of the way, doesnt it?

Philisophical question for the rest of the CPI gang: Since the engine cant be hand propped, why do we need an ignition switch?

My ignition is "hot" with the Master switch. If I really need to be "extra safe" or am performing extensive maintenance with the battery on, I just pull the ignition breakers. I feel that a separate switch only adds one more failure point.

Thoughts?

My coils will be hot with the master on-----either main or aux------but the CPI boxes will be switched via locking toggle switches.



I like the option to switch off the ignition if needed, without having to reach clear across the panel to the breakers, also it makes for an easy mag check.

I did ditch the ACS key switch in favor of a simple on/off switch from Stein, as well as the "Push to Start" he sells. Key only controls power to the start switch.

I strugled with the ignition switch thing too, but in the end I just couldnt think of a realistic circumstance where I would want to kill the ignition without killing ALL electrical.

Are you using the + - buttons to do your mag check, or pulling a breaker?

Using the + - function on the brain box.

But yes, I see where you are going.

My two cents with regards to the switches. The Rotec engine has dual electronic ignition and I used toggle switches as well. i used three different types of switches before I landed on one that I liked. One feature that I found important is the ability to secure the wires to the switches with screws vs blades. I had a blade vibrate loose on one of my earlier switches. After that I swapped them out for something with a screw. I don't use blades at any point in the wiring of the ignition system. Also I have two sources of power and ground running from two different points on the airframe.
