So I was assembling the tail assembly and walked away after putting the CA on the rudder tabs. Came back a few moments later and found the plane sitting on the ground. Well the wife needed something near the plane so she gently put it down to move it out of the way. So now my tail rudder is glued in place where the screw is. I am guessing the only way out of this is a new fuselage and rudder? I have tried loosening the rudder but it is on there solid now. Any ideas?

GoPro Video


Took the Carbon-Z out today for its maiden and had my GoPro mounted on the wing tip. Heres a short video of the flight.

Soak it with debonder for 10 minutes.

No worries... Clip off screw head at base of tailwheel bracket. Cut off the rudder and clean it up and clean up the fuselage. Trim the CA hinges. Cut new slots for new CA hinges. Cut New hinge slots and Install new CA hinges. When rudder is off unscrew the screw with needle nose pliers.

That should do it with no new parts. Debonder could work well too.

No biggie, I'll figure it out. I'm into this plane for the low & slow fly by
Did you check the balance of the spinner as well?

Also worth mentioning that HH likes to have you balance the hub area of tfe prop as well, using the little ears on the prop hub.

My prop and spinner was a very smooth runner right out of the box. Balance was fine on the prop both blades and hub and I did not check the spinner.

If you run out of debonder use acetone, that's what debonder is.

Awesome thanks for the debonder idea. Didn't even know it existed. Any particular work best? It was set with Zap CA Thin

I feel for you. After almost 33 years of marriage, not much surprises me any more.
Try heating the rudder screw with a soldering iron, then try unscrewing it. This usually loosens up CA or thread locker. Be careful not to melt the plastic. You may be able to work an X-Acto blade between the plastic parts without too much damage. I don't know how debonder affects the foam, so I can't recommend it.

BSi Debonder (green bottle) works pretty good. just let the stuff soak. thats the only way it will work. But it does work. it kinda "gels" the CA, so you can just wipe it all off afterwards. And the debonder has no adverse affects on foam of any kind.

Can't speak for THIS foam, but debonder/acetate will ABSOLUTELY eat foam!!! I'd suggest testing it on somewhere inconspicuous first like on the back of one of the hatches, before trying debonder. +1 on the heating of the screw, that's probably what I would do. I've even seen debonder eat PLASTIC.

Has anyone tried this to treat the foam?


Looks cool. I guess it won't yellow?

BTW, has anyone tried PolyCrylic? I'm not sure of the pro's and con's either way.

I changed the ESC to a Plush 60 and every thing works fine now but but both flap servos are buzzing. Tomorrow I will contact HH about the ESC and see if they have the replacement wing mounts.
Acetone will melt foam!

Here are the pics.

Do Not Use Accelerator on CA Hinges

Wash your hands after use as well so you don't accidentally touch the paint with accelerator on your fingers. I haven't had any issues with the post, are you sure you used the proper size screw in it, I can see where it could crack if you use too large a diameter screw. I believe spare rudders are in stock.

According to the manual for all E-flite/Horizon Hobby ARF kits I have built, they specify: Do Not Use Accelerator on CA Hinges

Here are exerts from the manuals of two different E-flite ARF kits:
1st: Allow the CA to cure
(without using accelerator) before proceeding to the
following steps.

Note: The CA must be allowed to cure without
the use of accelerator. Using accelerator
will not allow the CA to fully soak into the
hinge, and could produce a poor bond
between the hinges and surrounding area.


2nd: Deflect the aileron and apply thin CA to
each of the hinges. Make sure to saturate each
hinge. Apply CA to both the top and bottom
of the hinges.

Note: Do not use accelerator in the hinging
process. The CA must be allowed to soak into
each hinge naturally.

Please explain.
Thanks.

That is on Balsa ARFs, it is damn near impossible to get a good bond with just foam and CA without the kicker.
