move from 30p B1 to 32p B1
 
Can I move from a stock 30p B1 to a labbed 32p B1 without losing RPM? I know the answee will depend in part on how the 32p has been labbed, but am wondering if a 2 inch increase in pitch results in an rpm decrease that is more than the 200-300 rpm that you can pick up with the labbing. Thanks for any help.

"Standard" templated Labbing on a 32 Bravo 1 propeller will gain 300 rpm. The loss of rpm going from a 30 to a 32 is 300-400 rpm.

Many thing influence the numbers. Use the above as a rule of thumb.

Stock 30 to labbed 32 should spin about 100-200rpms less. It also depends at where you are in relation to you WOT throttle rpm range.

Thanks - Brett already spoke with one of your staff and am sending my paperweight/prop to see if it can be repaired - two ears are bent at 90 degrees and he thinks it might be doable? I hope.
