    Merlin Light Booth at Sun&Fun

    Along with the Merlin and Merlin Light at the booth at SunFun, there was also a super impressive low wing UL with all metal wing and tractor layout. I dont see any mention at their website... Did anyone happen to get a photo of that plane ? or have any details ?

    Harbor Freight Predator 670 V-Twin Horsepower tests

    I have put this exact engine on an adult sized mini bike and I can tell you that the power limit is not fuel air mixture limited ( bigger carbs or intakes or turbo chargers etc ) but the limit is sub par performance related to cooling. All of you guys are talking about elevated HP levels but...

    Rethinking Propellers?

    I live about 5 miles from Lockheed Martin which has made the C130 series of propped cargo aircraft for more than 60 years. about 20 years ago Lockheed switched their props from metal to composite and went from 4 blades to 6 blades. In my local EAA chapter was a member that happened to design...

    Sold Plans: Ritz Standard A Serial #181

    My understanding was that they never made plans available for this plane but instead supplied instructions for the assembly of the "kit". The difference was that most of the parts in the instructions did not have dimensions so the parts could not be created from scratch. I would be happy to...

    Amazingly ! the website ultralightnews.com is still up.

    Since about 20 years, all I have is thousands of organized photos on a hard drive. I gave a lot of photos to Loveman since he was putting all the effort into his websites.

    Amazingly ! the website ultralightnews.com is still up.

    https://www.ultralightaircraftmagazine.com/ This is like taking a step back in a Time Machine. Maybe the webserver fees are paid for a year in advance and when the server host current year is up the site will go away without the recurring payment. I seem to recall a way to find...

    Amazingly ! the website ultralightnews.com is still up.

    It has been many months since Dave Loveman passed but the large majority of his content is still available at his old website containing hundreds of bits of incredible info that will never be available again. I doubt if it can live very much longer without support and maintenance. It it...

    Kimbrel Dormoy Bathtub plans

    Kimbrell may not have had the best interpretation of the design. I think he took many liberties. Study the model plans for useful detail. I have these images in high resolution TIF files if desired

    glider rider ultralight magazine article

    I hope that someday as the technology gets cheaper someone will still possess the old magazines and convert them to digital. Then all we have to do is find an affordable way to keep and share this precious info. The EAA has let us down when we most needed them after they took our hundreds of...

    Ultralight Float Plane Concept

    I think it is time for a USA legal FAR 103 compliant seaplane design to take advantage of the experience and knowledge gained recently with the hydrofoils used by the boating and surfing community. I believe much weight can be saved in the hull design and and engine due to lower power...

    Horrible news from Vans Aircraft

    I am wondering if the problem with Laser Cut holes and cracks was due to the heat of the laser changing the temper of the alloy so that it became harder in the small region that was affected by the heat. Leading me to wonder if they could have somehow heat treated the whole laser cut...

    Photo Sharing Sites for ten thousand photos ?

    I have about four hundred folders with average 25 pics each showing details of mostly old ultralights. I collected these over about fifteen or twenty years and would like to find an intelligent sharing service that would allow navigation among the various folders and be user-visitor friendly...

    UL Aeronca C-2

    Ron, I think everything you said is true but the Le Pelican plans I dont think are pirated because the original designer or company providing the kit never had plans for the plane. Someone other than the original company or designer has created these plans which may or may not accurately...

    Looking for either Scout or Weedhopper plans

    I am with you on the Australian Wheeler Scout. I always liked that plane and from the large numbers that were sold and flown we can surmize it had a good reputation. Likewise for the Zenair Zipper by Heintz. These planes used the Princeton Wing concept of only having one spar on the leading...

    Does airfoil selection really matter that much? (Part 103 aircraft)

    Another way of guaging performance and efficiency besides fuel consumed per mile or per time, is time to climb. As I recall, for a long time a legal Delta Nomad UL with Rotax 503 and long "real airfoil -dope and fabric" wing held the record for time to climb to 1000 ft. Then years later a...

    Does airfoil selection really matter that much? (Part 103 aircraft)

    Option 3 as stated is simply not correct. It is easily possible to configure with the use of PRSU to optimize for climb at a speed substantially lower than max allowed speed ( prop blade at best L/D angle of attack at max throttle ) for instance 32 mph and as the plane speeds up the AOA...

    effects of moving the center of thrust

    Correction- I think "amphibious is too ambitious. Just stick with pure seaplane. You save all the weight associated with landing gear (25 to 50 pounds) which can be substantial. Further, if you use two floats, you will get a 30 lb each FAA weight exemption. If you use a floating hull, you...
