The CA 24% is probily the best flying Extra you can get in that size. I have a 38% version and some time on the 34% as well. Both of those fly very well so I have high expectations for the 24%. The saito will have enough power if you keep the airplane at 12# or less. Be very selective about what hardware you put on it to keep the weight down. A single 2100 mah Nickel metal battery will do the job. Sullivan steel control horns, don't go oveboard with the hinges. That 150 likes the cool power 30% nitro 30% oil fuel and use an OS F plug. Prop would be 16X8 Boly or Mej. Good luck, hope the pics will inspire you
