Can't see anything else I would do to it, looks pretty good to me. I flew the Up-Roars but I built the Dazzler for a friend to compete in fun flys with, great plane and does it all. On his I used the OS .46 LA and didn't mount it inverted but more like a 45 degree angle then built a cowl around the engine. I left the tail feathers alone because I kinda liked the look. I like what you did with yours though, sort of a Super Sportster look. The red and white look great together too!! I always liked the looks of the Dazzler better then the Up-Roar but I was killing so many fun fly planes I was scratch building the Up-Roars a lot, it's an even easier kit to build! The wheel pants you used gave it a nice touch too!!
