OK so I'd like to thank everyone for their opinions, it has seriously helped me A LOT! While I would love to get into true GIANT scale (that is, big enough to justify using gasoline engines and big, high-torque servos), I just don't have the confidence or experience yet to fly a plane THAT big and THAT expensive! However, I am considering larger glows, and I think the Giant UCanDo or Hangar 9 Showtime 4D 90 is a good choice for me. However, I did have one question about this. At the field the other day, I heard multiple pilots raving about YS engines, a company I have had no experience with. Then I went to my local hobby shop, and what a coincidence, there were 2 guys raving over the YS products too! I did a little research on the company and evidently they make unbelievable 4-strokes. But here's my only question. Usually, pilots try to slightly overpower their planes (at least the ones I've talked to). Examples: Saito 100 in .91 rated UCanDo 60, etc. However, the pilots I know using YS Engines in their .60-sized planes are using the YS-63. This seems like way too small of a 4-stroke to put in a .60 size 3D aircraft. Is there something special about these engines that I don't know about? I will admit, they are considerably more expensive than their counterparts in the same displacement. I ask because I am seriously considering buying the H9 Showtime 4D 90, which is rating up to a 1.10 4-stroke. Lucky for me, YS makes a 1.10. Will this be WAY too much power for this plane? Let me know what you guys think and what your experience with YS engines is. Thanks a lot!
