1. ### Second ignition for my VW engine

Another alternative for a primary or secondary ignition is the GMC HEI system It consists of an electronic control module, a dual output coil or two, and crank position sensors. It is easy and low cost to position one sensor at zero degrees and the other at 28 deg BTDC then use a switch to...
2. ### Yet another VW power argument. Again.

To understand the air-cooling challenge, look at the Jabiru engines that have engineered good airflow around the critical areas. A VW install could do the same thing for reasonable cost. Norm Heistand
3. ### VW Engines: Buy or Build?

I have built a half VW piece by piece after purchasing a good used case that had been bored and stroke relieved. I would not recommend building the engine from a collection of parts. Instead buy a new or reconditioned longblock then add to it. My thinking is stock engine with small supercharger...
4. ### Supercharged engine

Since the supercharger is simply an air pump, it would be easy to install a hose/tube from the blower output to the blower input. A variable shut off valve on the tube would allow changing the boost pressure "on the fly" with no other parts needed. Probably a way to have a control knob in the...
5. ### Supercharged engine

I have an AMR300 small supercharger on my Predator 670cc V-Twin. See it running on YouTube: http://www.youtube.com/watch?v=3gVygOvU83A The same type of setup would work on any similar small engine as well. Half VW, 2A042, 4A032, Kohler CH27, Honda GX690, etc. For a 1600cc VW or 4A084 I would...
6. ### Freewing/Sprat Control Wing Development.

I am currently building a Sprat103 from the plans set. The plans seem to be complete and adequate for me. My goal is low cost easy to build and fly legal ultralight. As far as maneuverable, what more do I need than turn and climb/descend? If you want maneuverable consider a plane like the...
7. ### The Sprat 103

I suppose it is possible that there are more builders in France working on building a Sprat103 since it is a French design. I plan to finish my Sprat103 this summer and test it out. How hard can it be to get a powered kite to fly? And the design is based on the flying boat that is/was flying for...
8. ### The Sprat 103

I can understand the critics of the Sprat103. There are very few of this design flying. My perspective is a little different. I have flown Cessna 150, 172, Rotec Rally, Benson gyrocopter, Phantom ultralight, and I have made emergency landings with the Phantom and the Benson. My engine failures...
9. ### The Sprat 103

Re: Any Progress By Builders? I am currently building a Sprat103 from plans. I got the plans from Bernard in France. They appear to be complete and accurate to me. I am subsitituting a 5/8 inch axle tube made of 4130 steel to work with my Azusa wheels. All my steel materials are 4130 or similar...

Yes, I have a Half VW built and sitting in my shop. It has the 94mm cylinders and the 82mm stroker crank. The intake is on top with a single Mikuni carb. The ignition is an electronic VW clone distributor with a sonwmobile coil. It is a full case version which I could bolt to a pair of aluminum...
