Just in, I had to send my ZDZ 50 NG back to RC Showcase because of a cracked engine. they sent me out a new 50 ng and after the initial run up I wa pulling 6690 rpms using my same glowbee tach and a newley balanced MSC 22x8 prop.

today i have about 2 gallons of penzoil mix through it and i'm getting 6900 rpms.

Power is definitely much stronger than the other NG, the uplines are very fast and know I can hover down low (very short periods of time) and punch out with good authority.

If the power gets any better i'll probaly start touching the tail on the Wild Hare Edge.
