Hello guys, I have a quick question for you, does the satio 125 engine come with a pump ? the reason why I am asking is because I am thinking to get this engine to replace my OS 91 surpass II with pump engine that I am using to power my u can do 3d 60 with the fuel tank located on the CG.

thanks in advance

no

what you do is either buy a pump or run a cline regulator. Im running the cline reg on my saito on my showtime 4d with the tank on the CG or as close as i could.

Thanks a lot guys.

One more question tho, is this engine as reliable as OS? What are the pros and cons of it? Will it be a good move going with this engine from 91 OS Surpass II engine? And finally will removing the muffler from my OS and running the headers only help with its performance a bit (I don't mind about noise)

btw, I had my share searching for the questions I posted above, but I Just wanted more recent answers than the ones I got from searched posts.


Thanks again

Ahmed

The muffler doesn't rob power on most 4-stroke engines...
And HECK YES!!! This would be a STELLER choice for replacing that weak 91!

I just love my Saitos... I have 3 saitos now in my planes and i wouldn't replace any of them. If you looking for which is better you are going to bring up a war.

Also consider the ys110. Built in pump, same price and power as the Saito 125, saves you $40.
