Thanks for the counsel Peter.

It's a Jeff Carder design, "Lightning" from 2011.He offered free plans and a short kit including wing and stab cores was available from Eureka Aircraft. It turned cold last fall before I could paint it, so now I'm waiting for spring to arrive to finish it up.

At our field there is a low tree line about 200 M out from the runway, so I've got a pretty good idea where 150M is.

I've used the trimming techniques on my little Extra, but its control surfaces are not very precise so it's hard to tell sometimes what effect the adjustments are making.
