Nice flyer! Two flights 1st w/ 4s3200s CG at 305mm, decent power w/quick takeoff, noticed it dives with power, climbs power off. Other than that it was very stable and glides forever. Landed very slow and easy.
2nd flt 4s2200 CG 310mm, short takeoff roll, a good thing on my dirt runway.
Dive with full power very pronounced with the lighter pack, Checked the stall high up, right wing dropped half turn recovery, Extremely slow speed needed to stall it, this jet is very forgiving! Landing is a non-event, retracts worked well, Both flights 4min, even the 2200 was barely warm. Fan sounded good, glad I balanced it. Next is adding a thrust tube for alittle more speed but it's mostly so I can add a shim to change the thrust angle.
Also going to chamfer the trailing edges, made a big difference on my F-100 so we'll see if it works on this one too. The slicker shape needed less power to fly and sharpened handling as well.
