    Second hand FireStar-2 need conversion documentation for Rotax 503 motor

    I have a FS2 with a 447. The reason I didn't want to go with the 503 in my build are many. The 503 burns a lot more fuel so I'd have to carry more fuel which means added weight (reduced ability to take a pax), plus the added weight of not just the engine but I'd also need to add ballast in the...

    Change.org: Urge the FAA to Address the Deficit of Ultralight Aircraft Instructors

    This is exactly what I predicted when talking with Chris that heads up the Midwest LSA Expo at the 2023 Expo. If a pilot has an airplane already and can't renew his/her medical, they won't be buying a new LSA after MOSAIC. They will fly what they have with just 1 other person. This will put a...

    Kolb Firefly Project - too much corrosion??

    I have a new firestar II that I just this year completed and got the airworthiness certificate. I also have a bunch of firestar parts (no fuselage). My advice would be to walk away even if that were free. Besides the corrosion, that's an oldy. There are too many good kits that are unfinished...

    Prop options for Rans S7 100hp

    I have a Rans S7 project that needs a prop. It had a Warp Drive 68" HPL on it but it needs new blades (one was broken and the other 2 are an old design they no longer make). I can send the hub back to WD so it can be checked out. I couldn't find any cracks but they know better where to look. I...

    Where do the Rans S7 folks hang out online?

    I saw that but I don't do Facebook for various reasons. Thanks VB, I'll try again at BCP.

    Where do the Rans S7 folks hang out online?

    Recently purchased a ground looped Rans S7 project. Looking for where online I can find a group to ask technical questions. Ransclan sure doesn't look busy from what I can tell. Rans' own forum isn't busy. Backcountry pilot doesn't have much going on either with the S7 folks. I'm probably...

    Airplane Wanted CGS Hawk II 2 place project, unfinished kit, or just unappreciated and needing work.

    I went a different direction. I found a Rans S7 short tail almost flying project with a very low time 912ULS.

    Ultralight covering prep tips

    I did a Kolb Firestar this Spring and I used the exact tape listed in the 2nd post, the Poly Fiber anti-chafe tape 1 inch wide. 1 roll was enough for my plane.

    Mounting Hirth 2702 Engine on Kolb Firestar

    I'm not sure which redrive that is as I'm not very familiar with the Hirth line. I know they used to have their own gearbox not a belt drive but maybe they offered both. My Rotax on my Firestar has the prop hub of the gearbox higher than the crank. I would think your redrive could go either way...

    Airplane Wanted CGS Hawk II 2 place project, unfinished kit, or just unappreciated and needing work.

    Looking for a CGS Hawk II, 2 place, either as an unfinished kit, something that needs rebuilt or is just collecting dust and not in use anymore. Ok to need new sails and/or engine. Am interested in the Arrow or Classic 2 seat models. If you know of someone who has one in a project condition or...

    "Thump Air" by KidKhaos6427

    All good info. I was looking at what his engine might be and it appears it is the Duromax 440 (the blue fan shroud looks like it) but he might be using one of the 460s as he mentioned when the engine was on his bench it is a 440, soon to be 460. The Duromax 440 is rated at 18hp and the Harbor...

    "Thump Air" by KidKhaos6427

    Anyone else notice the Youtube videos by Scott, aka KidKhaos6427 or kidkhaos on his "Thump Air" engine? It has electric start and with the redrive, carb, etc all up ready to fly is under 70 lbs. He has a few videos of doing some takeoff tests with his Thump Air engine. It looks like he's using...

    Carlisle Turf-Glide tires and tubes

    I've been gone a few days so that's why the late reply. My wheels are the 1 piece welded wheels not the 2 piece. I did get an answer from Carlisle, but it wasn't very helpful as it just said, "Unfortunately we do not manufacture a tube that would fit this size tire." They make a tube type tire...

    Carlisle Turf-Glide tires and tubes

    I have a set of Carlisle Turf-Glide tires that are 8.00-6 (8" wide for a 6" dia wheel). I also have a set of Black Max aluminum wheels that are 6" wide x 6" dia. When I mount them as tubeless they leak down so they aren't sealing well on the rims (yes, the tires say "tube type" so I expect them...

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

    Are you sure? I'm not trying to be contrary, however, even today the FAA doesn't consider an UL an aircraft. The FAA calls them "ultralight vehicles" in part 103 not "aircraft" nor "unlicensed aircraft" because aircraft have to be registered. I was told this is why UL don't need registered...
