    Current redrive options for Predator 670 project?

    Greetings, I'm thinking of picking up a Predator 670, and I'm trying to determine the redrive options that exist now. Here are the ones I know about. https://www.aceaviation.co.uk/redrives - Definitely the most well known, and likely the highest quality...

    Tractor engine legal UL with easy folding wings?

    Greetings, I'd still like to eventually have a legal (honestly under 254 lbs) UL. I'm done with pusher engines, so it would have to be a tractor engine design. Ideally, it would have folding wings like the Avid/Kitfox, etc. 4 stroke is a bonus. The first thing that comes to mind is the...

    How many V-Twins flying?

    Greetings, I've seen occasional comments about actual flying v-twin engines, but it's often hard to tell if they were DIY, or an actual product that someone sold. I know Hummel sells a complete v-twin, but I don't know how many of those are flying, if any. I'd bet most are DIY at this point...

    Airplane Wanted WTB- Looking for an Ultracruiser project near East TN

    Greetings, I'm looking for an Ultracruiser project for sale within 6-8 hrs max of East TN. I'd prefer an unfinished kit, but I'd consider scratch built or complete aircraft. Please contact me directly if you have something to sell, so I can have first shot at it. I've lost a couple project...

    Small, cheap mode-c transponder?

    OK, now that I have the Uavionix skyBeacon and skySensor installed, I should have the ability to broadcast ADS-B position. I'll fly it for the first time today, but I don't have high hopes of it working yet. Uavionix said there was something I would need to do in the configuration to make it...

    Looking for a small LED tail light

    Greetings, I'm thinking of adding the Uavionix skyBeacon/skySensor combo, which include strobes and red/green nav lights. That still leaves me needing a white rear facing light. It seems like everyone who makes these makes them with the intention of fitting the production standard (non-LED)...

    Small, cheap ADS-B solution now?

    Greetings, I'm flying a Onex, and have zero interest in controlled airspace. I currently have no transponder, and I don't really have space or the desire to install one. What I DO want is ADS-B out, preferably in anonymous mode. I want this just for some perceived added safety of letting...

    What happened to the Legal Eagle FB group?

    Greetings, I'm not a fan of FB, and I really despise the FB groups format. I MUCH prefer the traditional forum format, but sadly more companies and people seem to be using FB as their only source for information. There was a fairly active LE group on FB until about a week ago, then it was...

    part 103 electric motor battery allowance?

    Greetings, It's been a while since I tried to research this, but I'm thinking there probably hasn't been any good news for electric motor battery allowance for part 103. I know some have "assumed" various allowances, such as battery weight can equal 5 gal fuel weight, or battery volume can...

    Custom aluminum main gear for a Onex?

    Greetings, Some Onex owners have reported bending of the main gear over time, and in fact mine is starting to bend (un-bend really) after a couple hundred landings. Sonex doesn't recommend re-bending the gear though some have reported doing that. They simply recommend replacing the gear if...

    Inspecting welds on a tube frame?

    Greetings, I've done enough TIG welding to know what a good weld looks like. A good TIG weld is one someone else did :-) I've been trying to find detailed pictures of good OA or MIG welds on round tubing. I figured that would be easy to find, but my Google-Fu is weak today I guess. The...

    Weight variations?

    Greetings, I've seen a few ultralight designs that seem to have a lot of variation in empty weight that I can't explain. I actually had an Airbike (N-numbered) that was 350 lbs, and I could never figure out where that extra 100 lbs came from. If you take a set of wood wings like the TEAM...

    Aeropup

    Greetings, I'm dangerously close to ordering an Aeropup from the fairly new US dealer Aeropup | United States | Fielden Aero Home of Aeropup USA I understand there's somewhere around 65 flying in Australia, and that there used to be a single place version called the Supapup. From what I can...

    Kitfox, Just Aircraft, or?

    Greetings, I'm planning a future project that will replace my Onex, and I think I want to finally own something like a Kitfox. I would use the 912 engine (80-100 HP). I will NOT be entering any STOL contests, or landing off airport routinely, so extreme short field performance isn't needed...

    Oratex over bare aluminum tubing?

    Greetings, I've got enough Oratex for the Kolb Firefly I'll finish later this year, and it seems Oratex recommends (requires?) some form of primer on bare metal. They aren't at all specific about primers though. I've used the Polyfiber system on bare aluminum before, and never imagined having...

    What's the lightest covering/coating for an Ultralight?

    Greetings, If your goal was to cover ultralight wings with the minimum weight, what would you choose? Oratex certainly claims to be the winner for lightweight, which goes hand in hand with being the most expensive, and hardest to get. It doesn't require any coating, which is nice, and your...

    Options for legal UL with folding wings using the Hirth F23?

    Greetings, I want to build a truly legal UL, not just the wink wink nudge nudge type. The following is a list of requirement and preferences. The Kolb Firefly is #1 on my list, and actually the only thing on the list. Kolb isn't far away, so it's also a fairly convenient option for me, and I...

    Comelli emergency parachutes?

    I recently ran across some information about the Comelli chutes, and wonder why you don't hear more about them in the US. Compared to BRS, it's hard not to like the price, and also the lack of a hazmat rocket. Do they have a good success rate for deployments? I've only seen one video from the...

    Ultralight liability insurance?

    Greetings, I've read that USUA offers liability for ultralights. Is that still true? How expensive is it? My airport doesn't require it, but I prefer to have liability insurance if possible. It's pretty reasonable for my Onex, but any gyro is crazy expensive. I'm just wondering what the...
