Any words of advise on a Saito 90T, 90TS or 100T? Iíve pretty much settled on wanting a 90TS because itís a true boxer whereas the 90T & 100T run off a single crank pin. I think they also have more vibration than the 90TS but have no practical experience with any of these engines.

This is the backup can that I made thirty years ago but haven't needed to use

That is one seriously good looking can!

I have experience with all three, you will never see or detect any difference in the smoothness, only in the sound. If anything the odd fire engines sound better at low rpm. To me, that is.

A 100 T I rebuilt

Got to agree, run the same ones and then some. Rebuilt them from the sweet little 60t up to the 300.

The odd fire tend to run a bit stronger and sound better too.

This shaft and bearing where both brand new. It took 2 hours of run time to destroy it. He set the bearing on a steel tube and put the shaft in it. It didnít go on so he took a sledgehammer and drove it on. Instead of putting the bearing in a hot oil bath. He said he packed the bearing really good with grease and couldnít figure out why it burned up.

Wow! Youíre killing me. Iíd love to get a twin someday.

So the 90T is more powerful than the 90TS?

Iíve read that some have experienced crankcase oil draining issues with the 90TS.

Ok
i think you all have talked about this in the past. But this is the first time I have seen a heard shim. Is this necessary or is higher compression better

I have read the 90Tís have roughly the power of a fa-72. Would I be correct in assuming the 100T would have the power of a fa-82 then?

Good morning Mike, what engine is that shim from, Thanks. I've never seen one with a shim if I do I'll immediately lose it.

Perhaps someone installed the shim so they could run higher nitro? How thick is it?

Hangar 9 Cessna 62, it was called.
Thanks Mike, some guys didn't like the 15.5 to 1 compression.

I haven't always rebuilt Saitos, this is a Fox 50 I built from all used parts.

Here is a Fox .50 I made out of used spare parts, a .46 badly beat up crankcase, used piston and ring and cylinder, BOCA bearings, EZJust carb and MVVS 3245 muffler. The prop is a Graupner 10.5x6 in a Hobby-Lobby/Kavan backplateless spinner.

.13
i donít think so probably had running issues so they thought it had too much compression. Or they thought it needed a base gasket.
I sure donít know I am open for what you all think
