    Lithium Batts

    I have found Rotax has used 2 different voltage regulators. The small square one with 2 yellow wires requires a 1A constant load and will certainly "pop" a fully charged LiPo, The other style with 3 yellow wires does not require a constant load and I'm hoping it won't blow up whatever little R/C...

    Reserve lift indicator

    Great link. I'm rebuilding the dash on my Drifter and see I *must* make a space for one of these. That probe looks like a pain to build, some aluminum tubing epoxied to a small piece of flat stock looks much easier and lighter For a stall light you could plumb in an adjustable furnace pressure...

    A 5 cent cigar

    The FAA slammed the door in the face of the bottom end of the aircraft community when they closed the exemption for commercial use of experimental aircraft. A few years ago you could get some training in a challenger or hawk or... for about 75 per with instructor, now your choices are antique...

    What do you think about "e-soaring"?

    It warms my heart to see some asshole in a homebuilt airplane beating the big guys to this goal. Maybe he cheated by getting help on the takeoff but I believe he made a round trip while the other guys only went one-way so that's something... No matter what team you cheer for these people are...

    How much interest would there be in an Ultrasonic Altimeter for ultralights?

    Typical pilots, you guys are blowing a simple idea into a huge discussion. The OP said it would be nothing more than a toy to play with in the cockpit. I certainly wouldn't want to depend on it to save my bacon in a still water landing on a foggy day but that's what the $2500 one is for. I'd...

    How much interest would there be in an Ultrasonic Altimeter for ultralights?

    Can you count from 30 to zero faster than an ultralight on approach can fall out of the sky? Can you keep up with that count while you are trying to land that ultralight? I'm thinking it could get real confusing real quick while a tone would be much easier to follow Yes, exactly what I was...

    How much interest would there be in an Ultrasonic Altimeter for ultralights?

    My interest level would be dependent on your price level. No need for a display, just a box with a cord to plug into your headset giving you a tone that changes pitch as you get closer to the ground.

    Cheap ADS-B

    Navworx has a couple solutions available, one that piggybacks on an existing transponder and one that is a stand-alone ads-b in and out system. The portable one is not for certified aircraft but it is pretty awesome for $1000. My phone didn't like the SkyGuard website but what I could find...

    started soaring lessons today

    As I said, unlike anything I had previously experienced. Landing the Cessna is all about set the flaps and watch your airspeed and follow the meatball. Standard procedure landing a glider seems to be dive in at about a 45 degree angle with the air brakes on full... or maybe the instructor wanted...

    started soaring lessons today

    I took a demo ride with the local club last weekend. Takeoff and climb were great, flight was great and in the last 30 seconds all hell broke loose! Very different from anything I have done before and a bit overwhelming the first time around. Good thing the guy in the back seat knew what he was...

    Call it what you like, we are still talking F=MA and gravity *always* wins

    CAR-251: The Cheap Air Racer Discussion thread.

    That is my understanding of his math, although the rate of acceleration of gravity is 32.2 ft per second per second until gravity = drag and the velocity stabilizes so I'm not sure 1920 is the right number

    CAR-251: The Cheap Air Racer Discussion thread.

    Gravity is constantly trying to pull you out of the sky, level flight requires a constant climb equal to the acceleration of gravity

    Cheap ADS-B

    Half of the price difference between those two Yaesu radios is the lithium battery pack you must buy to get the added gs and gps features. Bad way to sell batteries as a good percentage of these radios will likely wind up hardwired to an experimental aircraft. Not real sure I would want to do an...
