    Simple pusher pseudo-jet

    Late '60's when Burt built the original and offered plans. If you can find a copy of the original "Death Race 2000" that came out in 1975 there's a sequence with Burt flying it.

    Someone finally built a manned "drone" and its worse than anyone expected

    All the hype about air taxi drones (whatever they call them) always amuses me. If you've ever flown an ultralight or light LSA on a very convective day then you know these things are going to be airborne vomitoriums. They better make the interior very easy to hose out. Rick

    Cascade Ultralights Kasperwing

    I was Cascade Ultralight's second employee and had one for a few years. I can't help you with the bolt chart but can offer a couple of pieces of advice. Steve's idea of "V" stability was total BS. Take some of the dihedral out of the wing. 3 or 4 degrees is good. 7 is ridiculous. Never, NEVER...

    Simple pusher pseudo-jet

    The Sadler was just another illegal fat ultralight trainer. I can't prove it but extremely doubtful it would have met the 497 lb weight limit. Rick

    GM 3.6L variants FYI

    Has anyone looked at the Chevy LTG engine? I've been drooling over it since it came out. All aluminum, turbo'd, and DI. Chevy advertises "light weight" but doesn't tell anyone what that means. I'd put one in a Lotus 7 or Caterham in an instant but obviously aircraft application would require...

    Steps to scratch build a VW

    Forgot something. Don't know if it's applicable anymore but from VW there were hi and low piston sets. Both would have a 5 gram variation in piston weights. The local VW dealer in Bellingham, WA let me spend a couple of hours going through piston sets to mix and match until I had a set within 2...

    Steps to scratch build a VW

    Another book you might want to pick up is HP Books, "How to Hot Rod Volkswagen Engines". The book is ancient, I got my first copy in 1971, but all the information is useful. The last engine I built was a very balanced 1600 for a bus. I could run all day at 65 with two hang gliders on the roof...

    Cracks found on Challengers

    When I was first looking at a two place "fat ultralight" I gravitated toward the Kolb series precisely because they have a welded space frame fuselage. After a week of climbing in and out of Challenger 2 I had in the shop I knew I made the right choice. Reading about QC's response to the bracket...

    GM LFX V6

    You might want to consider Burt Rutan's advice about alternative engines. Do your testing in a production aircraft. One, you've eliminated all airframe issues from your testing and two, should you find yourself having to do an off field landing the morons on the evening news don't go fretting...

    2600hp Hybrid Electric Turboprop regional airliner being tested

    Don't know how much effect it will have on a turbine electric airplane but I wonder about the effects on the airframe of always landing at maximum weight and lower MTOW. If you can't burn off fuel to lighten the plane then MTOW has to go down. Rick

    Mikuni carb size and Jet size

    One thing you might want to consider if it does not have it is a balance tube between the two intakes. Both the Legal Eagles built at 18KS did not have them as delivered. The HKS and the Rotax 9 series both have them. It helps balance out the two cylinders so there is less of the tendency to be...

    CNC Foam cutter

    As a buddy of mine told me, "perfect cores make perfect parts". Not quite as simple as that but I"m sure you get the idea. His solution was to cut all parts oversize by an 1/8" or so and than sand the cores to finish shape. Much more labor intensive than just letting the cutting wire do it all...

    ACE redrives for most commercial engines.

    Years and years ago I worked for Cascade Ultralights. They were using Honda 250cc 2 stroke engines and a belt redrive very similar to the Ace units. The tube carrying the prop pulley kept cracking. First we tried heat treatment, then ran a full length bolt essentially making the tube solid...

    Cumulus Motor Glider Kit For Sale

    Health issues force me to sell my unstarted Cumulus kit. Always stored in a heated garage, all hardware still in original blister packs, most in unopened boxes. The only thing I've done is assemble the wheels and tires and the throttle assy. I also primed the steel parts. See it at: Ultralight...
