    Roussel 30. French Lightweight Fighter

    I've always been interested in WW2 lightweight fighter designs and not sure why none ever made an impact. Seems like they'd be quicker to build, use less materials and be harder to see and hit in combat. Performance seemed nearly on par or better than many contemporary heavier fighters, at least...

    SDS CPI-2 Ignition Conquers the North Atlantic

    Our customer Mike Gordon flew his F-4 Rocket from SC to Germany after a 5 day trip last week. The SDS CPI-2 kept the fires lit with no issues giving very good performance and fuel economy running LOP at altitudes up to 18,000 feet. Typical TAS and fuel burn was around 175 KTAS on around 7.3 GPH...

    Subaru EJ/ EZ Gearboxes

    I was talking to Mike Talmadge in California today and he is still building gearboxes for the EJ four cylinder engines and EZ six cylinders. These GBs used the same layout as the Eggenfellner ones (designed to bolt up) but with everything re-designed, addressing all the previous failure points...

    SDS Service Bulletin April 2/24

    There was a machining error on a new batch of wide (3.50 inch) Lycoming Hall sensor brackets shown above. The spacing of the two outer 10-32 threaded holes which hold the red dual type Hall sensor in place are too far apart. The inner hole spacing for the single sensor is ok. If you discover...

    Laser "Powered" Research Aircraft

    https://www.avweb.com/press-releases/otto-aviation-selected-by-the-operational-energy-capability-improvement-fund-oecif-for-energy-web-aircraft-ewa-program/ Hmmm. While most interesting, I'm not sure how this would work outside an experimental environment. Cloud, precip, other aircraft or...

    SDS at SNF

    For those interested in RV-10s and SDS EFI, Krea Ellis will have his beautiful RV-10 at SNF this year and is happy to discuss his plane and the system. He will be parked in the Homebuilt Camping/Parking area which is pretty far east and just south of the VOR. Krea is a personable and super smart...

    SDS CPI-2 Ignition System Back in Production

    After about a 2 year hiatus due to EM-6 ECU development, we have CPI-2 ECU boards back in production, making ignition kits available again. We do have a fair order backlog on these so it would probably be mid April before we could fill new orders.

    300 Knot Lancair Legacy Turbine

    Well, we don't have a turbine engine section on HBA so I put this here. I know most folks here (including me) can't afford a ride like this but it's cool and it's a Homebuilt so dream and enjoy: My friend, Shane Daly owns the company who has put multiple turbine planes together. I hope to get a...

    LS3 Powered Murphy Moose on Floats

    Counterfeit Parts Warning

    A customer in NZ had a scare when an injector stuck open right after takeoff and shut down that cylinder. Fortunately he was on a long runway and was able to set it down and get stopped before the end. After sharing a photo of the injector, which he didn't source from us, it became evident that...

    Flying Race 6 Lancair Legacy

    Last Friday I was fortunate enough to be offered a flight in Joe Coraggio's Legacy while he was visiting here at Springbank Airport. He ran this aircraft last year at Reno. I shot some video and will put something together for YouTube later this month. Thanks very much to Joe for the...

    New VAF Forum Format

    Just got back from my new experience over on VAF. Ugh. They have taken the familiar and space efficient layout and butchered it. Some things are better left alone. Think I'll just stay over here on HBA. It's a friendlier place. :)

    Honda Powered BD-5

    This BD-5 is based at our airport and has been flying for a couple of years. Power comes from a turbocharged Honda 1.2L four and SDS EFI. There is also another similar BD-5 flying out in BC. Performance is reportedly excellent. Looks great! I hope to do a video feature on this one sometime...

    Recommended High Temp Adhesive?

    We're working on a carbon intake manifold for Conti 550 engines. It will use CNC'd 6061 T6 anodized injector bases that bolt to the cylinders. These will be bonded to carbon runners/ plenum. I've looked at Hysol products but couldn't find a temperature rating for them. Would need to have decent...
