RE: rubber bands
Jujst get some velcro not the strong stuff and sew a small loop in one end to fit around the rear hardwood rubber band peg make it long enough to go from peg over top of wing and under peg on front about 2 inches , then take the other part and sew it to the end overlap bout 1 to 1 1/2 inch pull snug and cut off about 1 inch from trail edge of wing
Now you have a long velcro looped over the back peg and it goes over the top of the wing under the front post and back over the velcro on top of wing - Pretty simple and easy to put wing on and off
Dont think it will work well we beeen usint this on sr telemasters and others with 26 cc motors and hauling up skydivers for over 8 years and never had a failur and do more stunts and other nonsence than most other flyers do with there wings held on with bands
If still confused pm me and I will give ya number to call or go to my website rcskyjumper.com and call and I will explane it
One yard of materal does about 2 sometimes 3 planes depanding on wing width-
may only change every 2 or 3 years unless one gets damaged
