I had both the Biplane like youirs and the low wing monoplane Starhawk. Mine ended up on the heavy side. And they flew that way, fast. Just Ok fliers. That yellow paint is also very brittle and will start to crack as soon as you get some engine vibration on it. I had it fall off in chuncks as it got some time on it.
Your pattern plane looks like it would be a good flyer. Looks like a Kaos wing, which is always good.
