My Posts This: Topic Forum | I have two N9's with both engines, SR and HZ(no pump) with Hatori pipes.
Both motors have their pros and cons. The SR is a 1900hs motor and the HZ is a 1950hs motor.
I like the way the Hatori mounts to the YS better since the SR has a different mounting system for the muffler. The HZ is fine too, I just like the YS better on that note.
Both are easy to start once tuned well and fairly consistent as a nitro motor can be.
If you want a little more head speed, get the HZ. I will say that the SR has plenty of power at 1900hs as well so again, no real difference there either.
I can't tell the difference between the two when flying. Only difference is the sound.
They both fly the N9 on the stock gearing really well so it's up to you.
Unless you have both to compare, you won't know the difference. |
