New Funtech 3D A395 vs Hatori 522 ---> YS50ST
Hello

This is my first Topic here but i have already been reading here since 3 weeks.

I ordered the a new YS50ST engine and wanted to know what muffler is the best to reach maximum power. Noise is no problem

I use 15%-30% Nitro and fly 3D

1. I saw a new funtech 3D out of one part (not A170 --> A395)
2. the good old hatori 522
3. other suggestions...

I read that some people need a rpm limiter with this pipes. is that true?

I like both the 522 (actually 521, I fly a Sceadu) and the Funtech A170. The end result is just about the same with either pipe. I haven't tried the A395, but I suspect it may be a one piece update of the A170.

I'm using the OS50 Hyper, 30% nitro fuel... I suspect you would see similar results with the YS with either pipe.

Your flying style will dictate the need for a rpm limiter more than the selection of muffler IMO.

I've used both the Fun Tech A170 and Hatori 521 on a YS50 and can't tell the difference in performance but the Fun Tech is significantly quieter (and i mean significantly).

Both pipes allow the motor to run smooth and powerful.

I also tried the MP2 and i can tell you that the quality of workmanship and machining on either of the Japanese pipes beats the Muscle Pipe by 200%. I'll never buy another CY pipe even if they offer the best performance.

Hello

OK i decided. I will take the

HATORI 522

for my Raptor 50

Why?
Becouse:
  • it looks better than Muscle Pipe
  • it has the same power
  • i heard it has better quality than Muscle Pipe
  • i heard it has more than funtech
  • it can´t get broken O-Rings like funtech
thanks
Kurt

Kurt,

You can't go wrong with the 522.

For the record... The Funtech A395 is a one-piece design like the 522 & CY MPII.

A395
I tried the old Funtech and it was not as powerful as the 522.

Look like this new version is trying to fix the leakings that happens to some A170.

This is really good for F3C guys who need a bit more power to fly the new schedule?
