Can i put an OS #F plug in a Saito 72

yes

In my experience the OS #F plug removes all the tuning problems that some associate with Saitos and makes it much more flexible. It's the best thing you can do to a Saito to make a great engine even better.

Not only can you, but you should... Better idle, more RPMs, what else is there?

I am using the OS#F in my saito 80 in my F40. Starts first flip all the time, awesome reliability, never have to touch it. Have put about 10 litres of 10% and 15% fuel through it on the same plug and the only dead stick ive had was when i got carried away and ran out of fuel.I had loads of hassels with the saito plugs, as the motor had not run in about 5 years, and I agree with the posts above, that the 72 will only be better with the OS #F plug.

HiTecMan,Ditto to all the above a OS#F is the best thing that you can do for that 72 next to running 30% fuel.Have you put that Extreme Flight up yet?

Ok that i will do. Nope I got down there and the day before my test-top my hs 81 stalled on the throttle. I will have to wait another two weeks!!!!!!!!

WoW! That's good to hear that it will help out the 72. I have a 72 that has given me fits and I checked it after reading this thread and found that I still had the Saito plug in it. Can't wait to try it out. Now all I have to do is come up with a plane to put it in......[:-] Any suggestions as to which plane....?

I havent flown mine yet but extreme flight rc.

Rob Clement RC...
Rob...How about a Ultra Stick 40 for that 72. I think that would be a nice combo.
Thanks,

Another would be the Twist. And, of course, any of the 40 size profiles. Also, a 40 size P51 would be a good scale plane. All of those sound interesting to me, and fun.
Thanks
Bud

Thanks CofG. I was thinking of a U.Stick. That's the first plane that came to mind. I was going to try to put it on a profile kit that I'm building but I can't get the throttle linkage to work out right. Thanks again
