If a forged crankshaft,electronic ignition & twin plugs,=Steve's Prop Hub and naintenace of 25 hour valve adsustment & oil shange and some very minor improvements, the 2180 there's not a more reliable engine if flown high *for cooling and less drag) and 75% power except for takeoff and climb thare's not a more reliable and inexpensive engine for that various mods of the KR. I have an Ellison and run it very lean. I expect it to last longer than I do.
Revmaster another great choice, time tested. Inexpensive engines, especially Steve's where the easy parts are done. There are some fancy engines out there, if one want to spend $2500 but the time the project is finished. I've love to have the 3100 Corvair with the 3rd generation crank, but I'm happy with with I've got. Mike
