    Certificated to experimental

    There is an exception to the charging for flights.. If there is a charitable donation made. Then it's OK with the FAA. So you can't fly to make money for yourself 100% that would infringe on the commercial pilots ... since the FAA is very much socialist/communist based ideology that will not...

    TWo Stroke Vs. Four, Why not???

    Their secret is money. Lots and lots of money. I know some of the guys that run Dakar. they have more money in those bikes than most have in a light sport airplane. Part of the idea is to keep the engine cost effective with in reason. Also they are running exotic valves and valve seats. They...

    Solvent for dried linseed oil?

    Good point... Proper protection should be used when handling powerful chemicals. gas mask with activated carbon filter, lab grade black rubber gloves, smock etc... The polar solvents can be very toxic and can also cause hereditary genetic mutations. They can form toxic aldehydes in the blood as...

    Solvent for dried linseed oil?

    Well Linseed oil contains large amounts of oxidized fatty acids. These have low solubility in non polar solvents such as WD 40 (water displacing oil formula #40) or alcohols such at methanol, acetone, etc. I would try a solvent used for dissolving fatty acids like ordering online.. an amount of...

    TWo Stroke Vs. Four, Why not???

    TWo Stroke Vs. Four, Why not???

    Pwood, I was saying that by selecting a forged piston you want to make the gap between the cylinder wall and piston larger. The forged piston will "swell" more than a cast piston. as far as the Eco motor OPOC.. I am not familiar with that one. I will have to do some reading. The best small...

    TWo Stroke Vs. Four, Why not???

    I take no offense by it. to be even more specific a stock air cooled non fuel injection 2 stroke engine I would not think is a good choice. Highly modified advanced engines, yes I think they would have enough reliability. I have worked quite a bit with modern high output 4 strokes. I have a...

    TWo Stroke Vs. Four, Why not???

    I would like to start off by saying I did not mean to cause waves on the forum. Everything I rant about is all in good spirit of sharing knowledge. I would be happy to explain, Most 2 strokes are set up to be bursts of power. Think of the application of 2 strokes: dirt bikes, snowmobiles and...

    TWo Stroke Vs. Four, Why not???

    Hello everyone. I have quite a bit of experience with liquid cooled 2 stroke engines. If proper maintenance and equipment is installed on the two stroke there can be many advantages to them. having rebuilt or built many racing engines. I can say that with very little modification a 2 stroke...
