[SPAM] RE: Tuned Pipe.

On a different but maybe related thought -
Ive run an OS 1.40, and a SuperTigre 2300 on a .60 size Hatori pipe
with good results.   Power is not as good as a 1.20 size pipe, but 
both engines ran nicely.

>I agree with Dean that I would not expect good results, if not problems.  However, I believe Mike Harrison ran a very similar set-up for a while when he initially converted from running 4C to 2C, as he did not want to/could not modify his airplane for the 2C pipe.  I recall being amazed it worked.  The set-up ran well enough, but once Mike adapted a 2C pipe, he seemed to prefer it.

Hello Fausto,
Don't believe everything you read on the net!  I wouldn't expect this combination to run well, and since there are many planes that don't fit the larger diameter two-stroke pipes, you would expect many people to run the setup you describe if it worked well. They don't, and it doesn't. 
Boa Sorte

Hi,
I'd like to know if anyone has tried or is currently using the following set-up with good results. The set-up would be a OS 140 RX, with original OS header coupled to a YS 4 stroke tuned pipe (HATORI #698 FAI Pipe for 120~140-4C). I 've read somewhere on the net that this set up would run fine, although I would not get the power increase as from the 2C pipe. Any comments will be appreciated.
Regards,
Fausto
