RE: Prop choices for .020, .049 and .061
Let's go with your .46 example....So if I have a fairly heavy model then it would be better to go for the 12lb thrust and the 12X4 instead of the 10X7? But then I don't understand why you have 16,000 rpm listed for both? Wouldn't the 12X4 turn slower than the 16,000 if the 10X7 turns 16,000?
