How to fix this tailplane?

[Sir Desmond Glazebrook]

I have been building a Hasegawa Ki-84. The kit is made to have an angled horizontal stabilizers. I trusted Hasegawa and affixed both with cement. They are stuck fast. 

I no longer trust Hasegawa's kit. It seems they have been mistaken. I don't know how to correct this error of mine. Any help would be appreciated.

If you used plastic cement, the joint will weaken after a stay in the freezer. Be careful, all the joints will weaken

Really? Wow!

Thanks Hubert!

What type of glue or solvent did you use to affix them? Try reactivating the glue if it hasn't been too long ( 24-48 hours, etc...).
