One of those Gotta have it kts back in the Day was the Skydart. it was just a majestic flying machine.
In the 80's I wanted to clone it and did, Painted it silver and have flown it pretty much to death.... I REALLY wanted to do a micro version.

Again we're talking 11 years ago when this project was undertaken... I decided we'ed try it in 10.5mm to give room for the T2+ internal pop-pod to house a wrapped drycleaner bag chute. I also decided to try to use .063" styrene for the wing & tail to reduce the amount of finishing needed...OH man this was a HUGE mistake. When all was said and built the model tipped the scales at a Wopping 20.6g add the motor and we were at 21.7g.
Needless to say the model just barely made it off the end of a 12" launch rod:( DEEEEE-RATTS!
Wasn't until 2006 when the OOP motors program came into being that I got a chance to actually fly this model successfully. Adding a 10.5mm Booster for some of my old Apogee 10.5mm A2-0 motors it finally flew, and glided just like it was intended.
During this process I also tried again building another this time using foamcore as the wing/tail but alas at 10.5mm it's just too darn heavy. this one was mated to a 13mm booster with some old A3-0T and A10-0T boosters for some really interesting flights.
I haven't completely given up I have an All Cardstock model in T3 designed just haven't gotten to build it to see if it'll boost by itself or maybe I'll design a 2 or 3 motor booster for the MMX-II-NE's.
