Hi All,
First trimming flights yesterday,perfect conditions with good weedy ground cover to keep the sand out of the engine.Final engine choice was the 25LA on 15%, prop MA 9x4 and a pacifier for fuel delivery.
First flight was a little exciting with three tight loops developing at approx 100ft before the engine cut at 4 sec pulling out into a glide for a few seconds before the DT went off.

Non destructive structural testing completed I trimmed 1/16 off the stab rear mount and after resetting the timer for a shorter DT tried again.
Flight two started to go on its back at the end of the 4 sec run so I cut off another 1/16 of the TE rear mount for flight three- much better but drifted off to the right at end of climb,added 1/16 left rudder for flight four- better,added another 1/16 left rudder for flight five, better again nice steep spiral good pull out and glide,a few more flights with longer engine runs and trying different launch styles finished off a nice day.
DT landing is a little dramatic with lots of bounce and noise but no structural faults noticed after ten D/T flights.
Fun model to fly and stays very clean with most of the exhaust gunk missing the airframe,easy to trim with docile handling,non critical to launch angles and looks very nice in the air.
