    Rotax 503 prop extension

    Had a "slight" problem after fitting a new wing to my trike, see avatar. The engine is a Rotax 447 with the 'B' box in the pusher configuration. I ordered aluminum blanks / bolts from McMaster-Carr. Original set up used 5 1" blanks but the vibration was a bit much. Dropped it back to 3 1"...

    What to do with this thing. 3 wheeler.

    Respectively; I'm not buying the 205 sq ft figure. Since the wing clearly states "Alpine 10" - I have to assume that it's a 10+ sq meter wing. Also, looking at the picture above, the center line chord looks to be no more than 6 feet or so. I just don't see how, with the (admittedly guessed at...

    What to do with this thing. 3 wheeler.

    The engine, prop and instruments may have some value. The wing is somewhere around 30 years old - I'd pull the aluminum and trash the rest. The trike frame; again I'd pull the aluminum and trash the rest. At one time this was probably an 'ok' setup - it was on the fast side of trikes looking...

    3D Printed Hand Holds

    My understanding about PLA is that its designed to breakdown in UV to be more environmentally friendly. You might want to check into PLA PLUS it's stronger than ABS and prints very nicely. No idea about the UV sensitivity. The testing I've done on TPU is strength (above) and gasoline (with...

    3D Printed Hand Holds

    Been flying with these for a while now and they are working out great, much better feel than flying the base bar. Printed from TPU on a Sovol 01 printer. To assure I had enough strength with the TPU I printed up a 5mm X 5mm coupon and hung 75 pounds on it - it stretched like crazy but it...

    I know ULs don't require a pilot's license, but...

    Once upon a time, before the LSA cr**, I gave ultralight instruction. The deal was; the student was to pay for the gas and oil and he was to bring me breakfast. What I learned was - skinny guys would bring me one sausage and biscuit, fat guys would bring me two...

    AZUSA wheels and tyres for Legal Eagle XL.

    I can't help with your selection but I will mention this; the five inch tires (street tread) are getting very difficult to find at least here in the US. I have one new set left and when they are used up, I plan to convert over to six inch rims.

    Noise Canceling Headphones

    Might want to take a look at PLA + (plus). I'm still on my first roll and so far I'm very impressed with the print quality and strength of it.

    Crashes in the News - Thread

    You need to watch the video directly, my copy is not that good. As I type; the posted video is the fourth frame down. I no longer have a Facebook account so I can't contact the author or the person who shared it. To me there looks to be a pitch change after the "black objects", but again this...

    Crashes in the News - Thread

    There's footage on Facebook's Trikepilot by Leo Lezzi showing what may be a bird/drone strike to the P-63 just before the crash at Dallas. I don't know it it's real, but if it is, it changes everything. Link here: Trikepilot | Facebook (scroll down a bit)

    Just found this...

    Just found this. The dang web, remembers everything! Fixed Wing Gyrocopter? Try A Trike! Fourth photo down, and twenty seven years ago. This is my first or second day of training, I don’t remember which, since it as a very long time ago. John Kimmeries is in the back, I’m in the front and we’re...

    Anybody know what this is?

    I wouldn't call it obsolete... old, yes. The problem with this engine was, if you moved the muffler from the original position (the photo above is in the original position) you could seriously screw up the return resonance and you would lose lots of HP. (22HP as I remember) I have one I've...

    Biplanes: Replacing streamlined wires with stranded cables

    I investigated the spiral wrapping of round tubes/rods a while back. Took two 3/8" fiberglass rods and added a spiral wrap to one. The wrap was just a piece of cotton string, taped on both ends with an approximate wrap of 1" spacing. Took them outside and whipped them around; the plain rod made...

    No Fly Zones for Ultralights? arcgis.com

    I’ve been flying ultralights for many, many years, and it’s really simple; DON’T P*SS PEOPLE OFF!!! Don’t fly over the same place twice, Don’t fly to low, Don’t do stupid stuff. (And this is {indirectly} from my local FAA – stay over the water and stay over the trees, we don’t care about you...

    That one special flight

    I was out flying my ultralight trike, making lazy circles - basically just goofin' around. And on one of my rounds I saw a large bird heading directly for me; I didn't think much of it. I figured it was a just a dang turkey buzzard looking for lift. Turkey buzzards are smelly, ugly creatures...

    3D printed Carbon Fiber Wing Ribs???

    There's a technique in 3d printing where the print is temporary paused, and a metal threaded nut or the like is inserted into the part and the print resumed. When finished, the nut is encased, making for a much stronger attachment point than the plastic alone. There's no reason why a properly...
