The engine runs smooth on the ground,good throttle responce.
The engine is off a Hanger 9 PTS P-51 which comes with the flywheel wieght. The high and low needles have limiters on them so us Newbies can`t mess them up. Also they claim it is broke in at the factory. Runs a little rich but still runs really good.
I thought maybe the added weight of the flywheel slows down the spool up time., but it does`nt on the ground. Just wonder if it is`nt sound travel thing, but being a Newbie ,I keep it pretty close to me.
Maybe I should go back with the Supertigre? I have a Magnum 52 FS that I was going to mount on it but the throttle linkage makes it a hassel to install.
Thanks for your responces, the help is appreciated.
The PTS engines are NOT broken in. They ARE pre-set but often wrong. They are within a range where they will work but not necessarily optimum. Newbies don't have to mess them up, the factory has done that for you too
. What a deal, eh?
Limiters? Nice pieces of scrap metal. That said, they do keep some newbies without instructors from destroying their engines.
Flywheel? Great idea actually. Only problem is that many spinner backing plates do not fit over them well. Not hard to remove though.
It could be sound delay time or some other matter of perception. 3/4 second isn't a very long time at any rate. Now if it were 3 to 4 seconds I'd worry.
