Hello, as some of you know I'm scratch building an Ultimate Bipe. I was planning on powering it with a ZDZ 40, But I saw a guy with a 3W 60 in his 62" Ohio Ultimate. I want to have PLENTY of power for 3D and such, so now I'm leaning twards the ZDZ 50. But I'm still not sure that'll be enough. I was kind of wanting to put a 3 blade prop on it so up to 60 cc's should be fine. I have never owned a gasser, but I hate payin 15 bucks for a quart of glow fuel. I have no experiance with gasser, so I don't know which ones start up easy, have the best RPM's and such. Any input will be greatly appreciated. Thanks, Jordan
