It is very true the guys at http://www.nicjasno.com drill the nozzles to make them wider when they make their lego engines to get better performance out of the cylinders

Just wana ask a may be stupped question but on the lego education site they sell theys pneumatic kits but the pumps and cylenders are made or a clear blue plastic . Are they as strong and durable as the yellow one's ? The reason i ask is cause i would like to buy pneumatics cause i have nonoe at the moment and want to buy 2 of these sets http://www.active-robots.com/products/mind...neumatics.shtml What do you guys think ??? ps i live in south africa so buying any thing online is a mission !! Thanks :)
