Re: Engine oil substitute

I've always found good prices and fast service from: airplaneoil.com
I haven't bought any AS Sport Plus 4 from them in a year so I don't know if they currently have any in stock.

Re: Oil all over the hangar floor...

As 3Dreaming noted above if you pour the new oil into the tank too fast it will overflow the neck and make a real mess. You need to have an appropriately-sized outlet on the funnel or carefully monitor/control the flow of oil into the tank so as not to overflow the neck.

Re: Shades vs hangars and maintenance

Shades are obviously better than open tie-downs but not nearly as good as enclosed hangars. Some things to consider when using shade hangars: -- Aircraft get dirty in shades real fast -- lots of blowing dirt but no cleansing rain (rain in California -- HA!). -- Paint, windows, interior, and avionics...

Re: Logon Bug

Yes! The Logon process has changed recently. I now have to Logon every time I visit the site -- annoying. Never had to do that before.

Re: Partial power loss and running rough

I experienced a similar partial power loss issue during climb-out in my RV-12 / 912 ULS. My Skyview EMS data dump suggested the right-side carb. It turned out to be a small amount of contamination in the mogas. I disassembled and cleaned the carb as well as cleaned a small amount of jelly-like crud ...

Re: EGT?

Whenever I experience or hear of an issue with erratic or unusual sensor indications my first (and cheapest) thought is to check the sensor's wiring -- usually a simple continuity check is adequate for troubleshooting purposes. Clean all of the associated terminal and connections. On some aircraft i...

Re: Torque Wrench

Some torque wrench observations: -- Some "click-type" torque wrenches have a very subtle "click" so be sure you can feel/hear it. -- Always unload or zero-out the wrench when you have finished using it for the day. And don't drop one! -- Small "beam-type" wrenches made ...

Re: Mogas refuelling best practices

I use a "jiggle siphon hose" to download the fuel from my 5 gallon containers into my RV-12 -- it works great and takes just over a minute. The container sits on a small temporary aluminum platform on top of the fuselage and the whole shebang is bonded to the airframe (and I also ground th...

Re: Mogas refuelling best practices

You should be concerned about the static charge aspect of refueling. Bonding of the fuel vessel to the airframe is more important than "grounding" to earth -- although including proper grounding is a good thing too. I installed a vent in my plastic container (see various videos on YouTube ...

Re: Has this ever happened to you?

I am curious -- why are the springs mentioned above factory-installed on the ROTAX/Bing carb? Could it be: 1) To provide some upward support to partially offset the hanging weight of the carb and its impact on the rubber socket?, 2) Alter/lower the frequency of carb vibration/resonance to reduce wea...

Re: saf-air oil drain

I have the Curtiss quick oil drain on my RV-12's 912ULS. It's leaking a bit. I gather that Curtiss wants you to buy a whole new valve ($$) instead of replacing the inexpensive "O"-ring. Does anyone one out there know what size and where I could buy just the "O"-ring for the big C...

Re: saf-air oil drain

If you use the standard oil tank drain plug, just be careful to not over-tighten it when replacing it. Check the ROTAX maintenance manual for the correct torque value.
