OS 1.08 vs 1.20
I've got a 1/5 scale Sukhoi nearing completion and I still haven't decided which engine I'm going to put in it. I've got an OS 1.20 four stroke and an OS 1.08, both wanting the job. I've flown both engines but never in the same plane or even similar planes.
Any of you guys have any experience with comparing the two? Specs show the 1.08 with more hp but how do they compare in the real world.
Wing span is 70" and weight will probably be 10 - 11 lbs.
I'm leaning towards toward the 1.08 but mostly because I haven't flown that engine in a dozen years. I'd like as much vertical as I can get.
