negative side of all this is the goo, I have had enough, no more glow , from now on its gas or lipo.
Yep the oil is a pain but Saitos seem to be the worst of the bunch when it comes to sliming an airplane. Not saying they are bad engines; they're great. They run well and are dependable. I've just found them to be gas guzzlers and spit a lot of oil. Some other engines seem to be much better in this regard. I get much, much less oil from my OS .91 4-strokes. The new alpha series is even better with their upgraded lubrication system. Even my YS engines don't make quite as much mess as the Saitos I've owned.
I think the main thing that O.S addressed with the alpha series was carb spit back. They put the velocity stack on the carbs. To check out the effect, I took one from a 56A and put it on my 52 carb. The carb bodys are the same PN between the. and I'm guessing that the other series also use the same body as their replaced equivlent engine.
THere is a quite noticable difference in the amount of spray back from the carb. That engine is cowled, and there is almost no oil in the cowl after the stack was added.
Some Saitos came with stacks and some didn't, but I'm sure you can get a stack to fit your carb, I know I just put one on a Saito 91 I rebuilt that didn't have a stack.
The O.S/Magnum cabs are easy to add a stack to, and on another thread, there were some nice ones made from soft copper tubing. It is worth looking into.
