Well built a Zingo with a twist. It’s the FAI size plane but of course built lighter than the FAI requirements. And the twist is that I built a Maverick style stab for it!! Pwr. is a K&B 3.25/3.5, ready to fly weight is 608 grams (21 ozs.) a little on the heavy side but very robust!!! See Pics. attached.

Nice looking model. Getting rid of the Zingo’s square stab really helps!05/22/2018 at 4:32 am #81978Roy SmithParticipant
Hi Scott, nice looking aeroplane. How does the wing stand up to the K&B schnuerlie? I had trouble with wing flutter on mine (powered with an OS Max 19 for the 1-design event). I had to double-cover the front of the wing (to make a sort of D-box) and then cap the diagonal ribs with kevlar before it was close to stiff enough. Of course, I didn’t use the thick ribs that the FAI version used. Mine ended up about the same weight as yours (20.5 oz).05/26/2018 at 7:42 am #81993
Roy, haven’t had a chance to fly the Zingo yet! Hopefully will be attending the Palm Bay contest next weekend and we’ll find out there! On the wing I built the ribs of 3/32 med. wood and prior to covering I put on Polyspan 3/4″ strips on 45 deg. angles top and bottom in order to stiffen it up!!!

Well, made it to Palm Bay Fl. last weekend for some flying! The Zingo made it through the first 5 flights than folded the wing in half on a had right turn pwr. pattern. The K&B 3.25 had plenty of pwr. and I didn’t see any wing flutter on it’s flights. Wing broke right where I stopped the Carbon fiber re-enforcement!#$%^& Will repair and try again.
