I broke the very first adapter when installing my SDS CPI last fall. Ross suggested that I have my torque wrench calibrated, which I did. It promptly failed! In fact it was so far out of calibration that the Lab was unable to certify it.
I immediately obtained a new torque wrench and had it calibrated by a certified lab. No further problems.....

Default Weatherpack Crimper

Some customers have asked us what crimper they should use for the Weatherpack pins. I ordered one of these a couple weeks ago and it works well plus is reasonably priced. You get a pin extraction tool as well which is handy if you make a mistake: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Default Les Kearney's RV-10 First Flight

I managed to grab a couple photos off the videos I shot a few days ago of Les' RV-10 first flight:





Looks great with the Show Planes cowling and 3 blade prop.



Aero Sport built IO-540 with fully optioned SDS EM-5 EFI/EI. Real purdy inside and out.

Ross - a couple of questions regarding the last photo posted above. I recognize this is earlier in the build cycle with no baffles etc installed...

1) do you recommend the fuel lines from spider to injectors be clamped to the push rod tubes at mid-span in order to reduce flexion under vibration?

2) do you know what sensor is plugged into the #3 cylinder NPT port often used for MAP or primer lines? I see a pair of white 22ga tefzel wires coming off the sensor and am curious what it might be.

Thanks for your patience. And yes, that is a very purdy engine indeed. Gotta love those SDS machined parts!

Yes, fuel lines should be clamped to the pushrod tubes in at least one place.

The sensor is for engine temp, used by the ECU primarily for start and warmup enrichment. Ignored once the engine is warmed up. 6 cylinder dual systems use one sensor for each ECU. 4 cylinder systems use a single sensor.

Thank you, Ross, for the quick answers. That sensor had me somewhat baffled!

Default Injector Hose Support



This is Les' engine again showing the very nice routing and support of injector and plug wires, plus the fuel line detail.

I get questions about how our ECUs talk to a typical EFIS and share info so I thought I'd address that here.

We only output rpm and fuel flow information to engine monitors at this time. The ECUs have their own temperature and MAP sensors which should be independent (not shared) of those on the EFIS for the best reliability.

Our ECUs don't take any CHT or EGT information from the EFIS.

In future, we may be able to share more info from the ECUs to glass monitors through serial or CAN connections.

Lightspeed has always had a higher torque for their adapter. The install process is the same as the SDS revised instructions. With the adapter at the higher torque, it will stay in the head when you remove the plug..... and that's a good thing.

Default New Billet Throttle Body



After having some recent supply problems with our standard 60mm throttle bodies, I elected to replace the modified cast aftermarket parts and produce our own design from 6061-T6 billet.

Trevor took basic the dimensions, added a few new features I wanted and did his usual CAD magic and machining.

This fits most 320s, 360s and 540s with standard carbs or RSA-5 servos. There are provisions for 2 vacuum connections and a 1/8 NPT port for an air temp sensor down the road. This one is also O-ring sealed at the base to eliminate the gasket as with our 45 and 80mm throttle bodies. We have throttle plate arms for both vertical and horizontal mounting, made from 7075-T6 as with our other models.

This is now a straight bore 60mm all the way through unlike the older cast model which necked down slightly. We pick up around 4% more airflow which may be welcome on 540s to free up a few more ponies on the top end.

This TB is much shorter and lighter than the carb or RSA-5 servo.

We also have a version of the 45mm TB to fit O-235s and O-290s.

In the works is also a 40mm version for a new project under development.
