Which engine configuration would you most like to see ?

could you tell me, how to dissasemble pneumatic switch ? I tried to do it, but switch was fragile and lose a bid part of air.

Because they are MUCH easier and simpler to mount rigidly, and require less effort to do so. This makes for a much stiffer and simpler engine in general.

maybe you guys could sell a tutorial book that explains how to build the engines and modify the cylinders and switches. i suggest a high price for that so that more people would buy that and pneumatics than a pre-assembled engine. also, if its a low price, more people would buy that and no one would buy engines. a suggested price: 100 euro, because if the a person buys a book, then buys pneumatics from lego education for about 47 euro then that is already more than the inline 3 2.0, then if people still need to buy pieces off of somewhere then that all adds up. then people would buy engines and the book because the inline 3 2.0 is cheaper than the book and pneumatics. again, just a suggestion.

can you sell just modified switches and cylinders?

thanks for using my poll suggestion! also, here is another suggestion: where do you use pneumatic engines: cars, display, mechanics, other? i also have a question: do you use html when creating the poll? if so, what website do you use to generate the poll code?

My suggestion is to ask whether you want standart engines with pushrod or camshaft or SYS engines.

Allright, allright.... A V8 is in preparation! :)
