hi friends i have made a catapult-glider out of biofaom with coroplast as fuselage and it worked successfully and i will show you the pictures here.i did this because of help from every member here in this forum.thanks to all.i have used
1. balsawood spar for wing
2.visiting card for vertical stabiliser.
3.balsawood nose-doubler for catapult on one-side of fuselage so that coroplase doesnt get teared. this worked very well.

Problems:
1.is it necessary that nose-doubler should be used on either-side of fuselage nose for aerodynamic reasons.
2.then cutting of coro for fuse should be carefully done otherwise decalage would be negative.
3.Fevikiwik should be used so that it gets stick to the coro easily but we have to wait for a few seconds.

Will coroplast can be a good option.what you think the problems could be faced?please give comments so that everyone can explore the new material properties.

i test flight it with the needles on the wing with fuselage without using glue and due to more wingarea it flew excellently even with the presence of needle-weight.

hi karthik

nice building bro. it seems you are a glider man like me why don't you try packaging foam ?? and build a bigger model something like 26 or 30 inch span.

the plane looks cool

best

i dont know how to use biofoam as fuselage without reinforcement.please guide me

sure i post a build log here once I'm done with my plane (mostly be after Sunday)

bye
