22x8 Or 23 x8 Mejzlik prop for the 55?
22x8 ones it's broken in.
23x8 on a tuned pipe.
Due to its weight, the Mezjlik won't accelerate as fast as eg the Vess 23A.
I used a 22x8 mezjlik for break-in on a DL50.
23x8 mezjlik is totally fine on a DL50, or 55 and will accelerate nicely. It has lower load constant than Vess and Xoar.
With a tuned pipe, you could run 24x8 prop.
