Hey Jeff,
I've got a 26cc gas in her and the power is perfect as she will take off at about 1/3 throttle and will fly for 30 or 40 minutes on an 22 oz tank. When you build your struts be sure you understand just how much load they will be carrying. If you want I'll send you some pictures in a pm of what happens when you build them as per the plans and what we did after we learned about it...lol I don't want to post them here and create issues that are not needed on your build thread.
TTYL,
Bruce
