I dropped exactly one drop of 1:40 oil and av gas on my beautiful leather headrest. Does anyone know of a leather/oil cleaner that would not make a bigger mess?

Sure, newer OMELED phones are brighter but...

Amongst all the weighty deliberations on improving safety, maybe someone experienced and knowlegable about diaphrgam carburetors could give me guidance. I fly a PIK 20E , Rotax 501 unreliable engine which has been behaving erratically, surging but not misfiring that I can detect. From the plugs...

There has been less flying this spring due to Covid-19, yet a 30% increase in horrific accidents in the US 2019 vs. 2020. A letter went out today urging several good ideas to consider by clubs and businesses to help reverse this trend. Webinars, ground school sessions, additional dual checks...

Playing off the US success at the 2020 WWGC, our family is interested in partially sponsoring one or more mentorship activities to support the training of women glider pilots (for early phase, rusty, competitive, XC, aerobatic, demo flight, etc.). Unlike some other funding sources, the money would...

I am thinking A CG tow hook for the towplane, likr RC models do. This way Glider can stall the tow plane while kiting, but not point its nose down. I envision a tunnel for the tow rope along the fuselage top so it doesn't jam the rudder/elevator. The front end of tunnel/rope is connected to the...

I'm looking for a good charger for my PowerSonic AGM batteries. I have a car charger, but that seems to be malfunctioning, as it doesn't seem to want to charge car batteries or my glider batteries. Any recommendations on a good charger for these type of batteries?

I know there is a thread going on about and around the latest tragic accident from 5-9-2020 and I preferred to start a new thread as I felt uncomfortable going into a dry technical discussion in the context. So the issue is: I would like to know more about the aerodynamics of the towplane in all...

I'm in the country south of Blum, TX where I've just completed my new gyro plane kit.Â* Unfortunately, the as delivered brake master cylinder was faulty, so I've had to tie the aircraft down for engine run tests.Â* Otherwise, everything worked perfectly except for a very small coolant leak...

Does anyone have an IGC file from an IGC approved PowerMouse? I am seeking approval for the non-IGC version as a Position Recorder from our NAC. My club put them in our K-21B's where they will do the occasional 5 hr and 1000 m height gain silver badge legs. I am trying to ascertain how to...
