    Building a VW Aero-Engine

    I can probably find it somewhere...but I'll just ask. Do use the VW oil slinger to keep oil in the case? Or, do you use a sand seal?

    Stroker engines in airplanes

    I'm using the HAPI accessory case because the pattern matches my Sonerai fuselage. I shaved the engine case of all the excess material as you mentioned. Eliminating that case would save a little weight as well. Without the magneto, it is nothing but an engine mount.

    Stroker engines in airplanes

    I have a set of Scott's cylinders on a 1835cc (formerly HAPI) engine I am building. I'm just experimenting to see how low I can get the weight. I want to test the durability of his cylinders in the process... working hard to ensure adequate cooling. I think the aluminum cylinders got a bad...

    Stroker engines in airplanes

    At set of NiCom cylinders from Scott Cassler would get you under 130 pounds ;)

    Stroker engines in airplanes

    He said that he was running at 26" MP. The 83 HP estimate would be static power at sea level. One can get a pretty good estimate from prop diameter, pitch, and rpm.

    Stroker engines in airplanes

    I believe the Baja 1000 contestants would argue the assertion of "high HP only for short periods." I believe the takeaway is that the VW heads are capable of removing the heat as long as the airflow is sufficient. This is a bigger challenge in slower moving aircraft. Faster aircraft have...

    Stroker engines in airplanes

    Interesting that the ground-dwelling VW engines do not seem to be limited by this 80 hp wall. The turbo-charged Aerovee is boasting 100 hp....with fairly standard VW cylinder heads. I would be interested in hearing from owners of such engines about cooling issues. I would hate to see the...

    Human CG position relative to seat

    The easiest way to find the pilot or passenger moment is to put a scale under the small wheel and record the weights with or without the occupant. Then simply do your arithmetic.

    Advice, please. Considering a Sonerai II.

    I’ve considered putting an AMR500 supercharger where the starter is normally located (6 o’clock).

    I just hope we don't lose our identity here. The Sonerai.net forum was always friendly and helpful. My experience with larger forums has been that there are many posters who simply wish to prove they are smarter than everyone else. Let's do everything possible to maintain the tenor we had on...

    Advice, please. Considering a Sonerai II.

    I weigh 145#. My passenger weighed 190#. We climbed at 500 FPM. Conditions were dry and cold... under 50 degrees.

    Advice, please. Considering a Sonerai II.

    Hi Vince, I flew a Sonerai II out of Prescott (5,000MSL) behind a Revmaster 2100D. Dry weight was 590#. I flew it dual in the winter and solo in the Summer. My Summer rate of climb was over 500fpm at 80-90mph.

    Chucker's Sonerai II (minus)

    My last Sonerai had Gurney flaps on the exits. I tip my hat to Dan's ingenuity, Even though they look draggy....they really are not. The air backs up on the front side and creates a fairing all by itself....just like running without a spinner.

    Chucker's Sonerai II (minus)

    Changed my mind. The gurney flap is too ugly. I'm going to build faired ramps in front of the exits to provide the necessary low pressure around the opening. Pictures soon!

    Wanted 2180 cylinder

    Did you check the torque before you removed the head? I'm just curious as to why the gasket failed. I prefer to not use them...the iron to aluminum seal wrks fine as long as you don't lose torque. People often blame the studs for lose of torque. I don't think that is the cause. My VW...

    Wanted 2180 cylinder

    I have a set of four...but shorter stroke (69mm) Check out this price: https://aapistons.com/collections/vw-piston-liner-kits/products/92x82mm-2180cc

    Chucker's Sonerai II (minus)

    And here is the ugly, draggy part! However, the entire bottom side of the cowl will be closed and smooth and there will be no exhaust pipes hanging in the breeze. Overall, I am expecting lower drag. The Gurney Flaps are fairly large to start. I don't want cooling problems out of the gate...

    Chucker's Sonerai II (minus)

    I am definitely planning on a lip.... a Gurney Flap. I'm thinking about making it controllable from the cockpit....but probably not. I'd rather keep things light and simple. As "Pops" says on the Homebuilt Aircraft forum, "If it is not here, it costs nothing, weighs nothing, and is 100%...

    New Cooling Concept

    Chucker's Sonerai II (minus)

    Been a long time since my last update... I'm installing an 1835cc engine and working on the cooling. As you may remember from my last project, I don't like hot air inside the cowl. On that project I used updraft cooling and ported the hot air out the top of the cowl. It worked well...
