The Octagon 29.5"
a variation on a Nutball
This large NB variation is built from 6mm depron and has a KFm2 profile...that is a 50% top step.
The build notes start here and the info applies to any of the KF stepped wings..
If you dont like the octagon shape make it as a circle at 32" diameter...This is my BIG nutball ....Both fly superbly as R.E.T controlled planes..
The original nutball started as a 17" dia epp construct...and is one of the most fun things to fly...If you havnt built a nutball .. read the thread ..then add one to your fleet ..they really make you smile
The youtube video is here..
.Dont be put off by the one in the picture which is tatty..This was made by cutting up a different version...Like the nutball it flys very very well, from exteemly slow to wild and fast
