Default EM-6

Dear Ross,

is there an ETA for the EM-6?

Not at this time. The extra long CPI-2 development has drawn the EM-6 completion date way out.

Default Another SDS EFI RV-10 Runs

I put together a short video of Les Kearney's new RV-10 making first engine runs today with SDS EM-5 EFI doing the fuel and ignition management:

https://youtu.be/0vU0h2d-gW4

We hope to do some more videos featuring his RV-10 as we go through initial tuning and eventually flying it.

Iím really interested in the tuning method. I hope you make a few videos of the process.

Default SNF

For those of you at SNF, you can drop by the Aero Technologies LLC booth NE41 and see an EM-5 setup on an LS-3. Talk with Scott there.

Default Service Bulletin

April 26/19 Service Bulletin Regarding 18 to 14mm Spark Plug Adapter Installation

Due to a number of broken brass plug adapters, we've changed the procedure for installing these as follows: 1. Thread the spark plug into the adapter 2. Torque the assembly into the cylinder head using the PLUG hex to 19 ft./lbs. 3. Torque the ADAPTER further to 25 ft./lbs.

Use only a thin stripe of anti-seize compound on the plug and adapter. Do not coat the threads. Although we've done multiple yield tests on the adapters torqued into a fixture and they fail at 32-35 ft./lbs., a number of people were snapping them at the originally recommended torque of 22 ft./lbs.

Default Torque education ?

Ross,
I have been using the Pmag install process of the plug in the adaptor both torqued through the plug at 18 ftlb. I now have your CPI kit in another project. So, what should we know about the difference between 18 ftlb and 25 ??

Hmmm... here I was thinking I would order up a set of your adapters, Ross, to replace the ones that came with my P-Mag. Many posts here and elsewhere have given the impression the SDS adapters were the best of breed.

With what you have learned in your testing, am I likely best to use a similar torquing method on my P-Mag-supplied brass adapters?

(I know, you can't speak for EMagAir and I don't expect you to, but you can speak from your engineering experience with respect to the generic aspects of the interface between steel spark plug, brass adapter and helicoil in the cylinder head.)

In our opinion, 18 ft./lbs, may not be enough torque for the 18mm adapter to keep it in place. The plug OEMs recommend 22-29 ft./lbs. for 18mm plugs.

As I said, they don't yield for me, with my torque wrench, when lightly brushed with anti-seize, until 32-35, yet people are apparently breaking them at "22". I found one user who broke several had a torque wrench which was almost 30% off from mine when we put them together. Others I suspect are are lashing the AS compound to the threads which increases thread tension at the same torque.

With the spark plug in the adapter, you won't break it any more. I know other manufacturers want you to install the plugs first, likely for the same reasons.

We often learn that people in the field can break stuff that works fine for us. We have to find a solution and this procedure is easy to implement.
