RE: Reaction 54 Jet Kit
Bob,
He did fly it stock, but said he had a bad habit of overshooting our 460x40' paved runway. I never saw it fly myself. Our field here is at 3180' above sea level, and I could see it having a higher stall speed on a hot day. He said with the spoilers, he had more control and was able to keep spooled up a little higher on final.
As you see, If I don't like them, it's an easy fix to trim them back off. I know the Curare pattern ship back in the day used them in the downlines to keep from building speed, and you could use them on final to slow the ballistic speed down.
