where can i get a set of airfoil rudders fairly cheap

i ran 78s in mine no black smoke and it ran cool

i disagree you almost cant tell the differnce in the snap my dad ran a 3 blade whirlwind stump puller on his 520 forever and he tried the two blade stump puller as well and the 3 blade way outperformed it on the hill in the water everywhere but as for the super snapper i have never been very impress...

definatly need to stay with aeroshell ownin a 220 myself ican tell you i tried the rotella and it burned more oil aeroshell is heavier than the rotella as well

its actually 12 quarts for the 220 says so right on the oil cap of mine
