L4 Piper Cub Fuselage Dimension
Length from firewall to rudder base 43 inches
Width at firewall 5.5 inches
Width at the cockpit 6.0inches
I have five days Chinese New Year Holiday. It was really a good time to start building my Giant Scale L4 Piper Cub.
Materials
My original idea was to built L4 fuselage from a foam. But after looking around in my storeroom I didn't have any foam supply left. Again cost cutting play the role here. I need to buy new foam. No..no.., then I saw 3mm playwood sitting around, a left over of my abandoned quarter scale J3 Piper Cub. Then I thought why not I tried to built the L4 fuselage from the 3mm plywood.
Weight Problem
3mm plywood is heavy compare to balsa sheet. Well I have no choice but to cut a lot of hole in order to lightening the L4 fuse.
Tools
Normal hobby knife with a lot of "hand's power". It really made my thumb and point fingers numb. Well, at least it was good exercises for my hand.
Glue
Combination of Dunlop Contact Adhesive and a little bit of 5 minute epoxy. The secret of using Contact Adhesive(CA) is to apply on both surfaces, wait until it dries (abount 5 to 10 minutes) and joint it together. Never,never apply too much CA, or it may result in weak bonding.
Covering
At the moment I am thinking of covering the L4 Piper Cub with regular white cotton fabric and then to apply automotive paint. I had made an experiment yesterday evening to test wheather nitro fuel will affect the autopaint. It seems that autopaint did not get affected by nitro. I think I will go ahead with the techniques.
