    Hanger 9 piper cub

    I had a problem with the old hanger 9 piper cub 40 while having a rough take off the firewall split in half, now I would like some opinions, would you guys remake a new firewall, or glue / epoxy it back together? I, sorry I don't have pics at the moment

    RE: Hanger 9 piper cub

    I wouldn't just epoxy it back together without using a doubler or some reinforcement. I'm assuming this is a glow engine plane, so since the tank bung and engine mounts will have to go thru any doubler you make, it would probably be easier to just make new firewall.

    Luckily it was a clean break. I took and epoxied it back, I'm gonna give it a stress test tomorrow and let it run on the ground and if it don't hold up ill make a new one!

    A basswood doubler epoxied onto the back will make it strong enough. Your only real worry is vibration weakening the glue joint.

    Hi Eray2012
    You state that the firewall broke in half. Something seems wrong here. I would not glue it together. I would replace it with a piece of plywood, about 3/8" thick, and use 1/2" quarter round balsa in all corners, both sides.

    What's so wrong aabout it splitting in half? 1 side stayed connected to the frame, the second half broke off

    Hi Eray2012
    I guess I am assuming that your firewall is plywood, and that plywood would not split in a rough landing. I have been in R/C for over 40 years and have crashed hundreds of times. It appears my assumption is wrong.

    RE: Hanger 9 piper cub

    For a model to take that type of damage it must have hit pretty hard.. you may want to grab the fues font and back and give it a gentle twist to see if you have any other unseen damage as well. Many times longerons and other joints are cracked.... you'll hear it if they are or you may notice the fuse twists more than it should.

    Did the firewall split vertically or horizontally and I assume the break-line was outside of the motor mout footprint?

    Vertically! And the frame is still solid I checked it before I epoxied it back together! Yall don't understand, I fly in a cow pasture so if you hit a pothole with alittle speed it flips over
