Engine for a SIG SE
Hey Mike, I think the Irvine .53 would be an excellent engine for your SE (love the .46 in my 4*), but you might also want to consider the Webra .50. I'll bring my SE out to the field tomorrow if you wanna try it out. I haven't flown it for awhile, so that will be a chance to run some fuel through it. Hope to see ya there...
