I believe the saito 325 radial is the only saito radial, that has a Tubinator. This looks like a flywheel, and flings the fuel around, so it disperses better...
I believe this one runs well w/o on-board glow power....
It also has twin plugs....10-glow plugs in total...

Not sure if the saito 200 triple, has this or not....
Looks like a fantastic engine....I think it is perfect for this plane....


Also.....
The syssa Sap 180 will be Perfect for this plane.....
Should give great power, with just a little extra, to get you out of trouble, if need be...
