checkmate maxxum
 
my dad has a zt 280, its got a brand new 502 mag in it, took it out yesterday and only got 61mph out of it running at 4300 rpms but should go 67mph at 4600-4700rpms. Any suggestions on what could be wrong, i thought maybe a differrent prop

my dad has a zt 280, brand new 502 magonly hitting 61mph at 4300 rpm's, do we have to change the prop. Any suggestions on what could be wrong

Need to know the prop on it now and drive ratio. Then can decide if you are over-propped or if engine is down on power.
