I've never considered a Saito for pattern ; having favored YS and OS Engines of various flavors. However, the expense of running my OS160 FX and OS140RX in my 2 meter aircraft continues to escalate towards the absurd because of the price of glow fuel.

The new Saito FG-Gas is an intriguing powerplant for 90/120 aircraft because of its weight ( 35.3 ounces with muffler and ignition) , 10,000 RPM capability ( don't know what size prop here) and ability to swing a 15X7 three blade- all as per Horizon website- don't blame me if this is wrong . Don't know the BHP.It may be capable of pulling around a FOCUS SPORT , VENUS 2 , or as a stretch , the new AQUILA ( maybe for the lower classes, here). The other two aircraft ( and others) should be able to handle the Master's sequence as PRACTICE AIRCRAFT , but not saying for sure with this powerplant. We already know that the OS 120AX and YS 110 are the current powerplants of choice for models of this size. The SAITO FG-20 will run all weekend on a gallon of mixed pump gas- The SAITO ad states up to a 90% decrease in operating costs. It could be a pig , suitable only for 60/120 ARF Warbirds and Cubbies , but time will tell.

The OS 120 FX with muffler weighs 29 ounces , a tuned pipe will save a few , but will increase costs. The SAITO will probably require a 6 ounce tank vs. a 16 ounce for the OS & YS. The ignition battery could come in @ 3 -4 ounces. Right now , the engine is pricy @ $529 , but there is talk on RCU of dealers selling for slightly under $500. Still not cheap, but the fuel cost savings will have it covered in no time . I'm not ready to take the plunge just yet , but it is certainly tempting.
