I have been following Paul Lamar's blog's reguarding water spraying the Radiator and I guess the engine internaly of the 13b rotory, Mainly the Rad. during take off. There has also been talk of maybe useing diamond or crystal type of len's for pickup on the ignition inside the engine. One guestion I have, is the aircraft equiped with an extra tank to hold spray fluid ? and if so what is the norm on size ?
