Default Hangar 9 cherokee tail problem

Hi, just made my test flight of my new hangar 9 cherokee, the test flight was a great success. However a close inspection of the plane after landing, i came across the fact that the tail is not properly glued in and is some how a bit lose. My question is how can you glue the tail back in properly. I tried pulling the tail out, but was unable to. It would not come off. when i move it it would not stay straight though. The top of the fuselage is plastic and their is no access to the tail part. any suggestions is appreciated.

Which part of the "Tail" are you refering to thd stab or fin? I assume you are refering to the Stab,
if so you should be able to wick some CA into the joint, but make sure it's where you want to be, or
you will have some major surgery to follow to. Somthing else that can be done is remove a small
portion of the covering from the bottom of the fuselage near the tail feathers and cut a small hole to
get some epoxy from below onto stab, recover and it won't be as noticeable.

HI,
Thanks for the reply. I am taling about the Fin and not the stablizer. I alos thought of cutting a small hole on the plastic side of the fuselage and get eboxy inside and then cover it with tape or some other means.. but i dont want to screw things up. what do you think

Sounds Like a loose CA hinge to me. Not properly glue in. Read the sticky at the top about CA hinges that minnflyer posted. Explains it all. You will need to buy some thin CA and a 99cent CA applicator to apply the CA correctly. There is no need to drill any holes, the thin CA should wick into the hinge. After appling the CA it will seem a little stiff, just work the fin back and forth and it will loosen up somewhat , and you'll be good to go. TRY THE THIN CA FIRST before you start drilling or cutting. Worse case is that you'll have to cut the hingees and reinstall new ones, and that will be an adventure!! So just try the Thin CA first. From what you have described, it should work just fine for you. Best thing is, no dissassembly required and you can fly again in 15 minutes!

sorry, i am new to this and i seem to have given the wrong information, i am not talking about the hinges of the rudder, i am talking about the rudder itself, its supposed to be glued at 90 degrees to the horizontal stabilizer, and its not glued in properly, and the problem is i cant reach inside and glue it properly? Advice please

Think Twice...Cut Once!

Chances are the vertical fin rests on, and is glued to, the horizontal stabilizer. The part of the fuselage near the tail that comes up from the stab and curves over to the fin, might be more for aerodynamics and looks, rather than strength (Although I cant be certain without having the model in front of me).

If this is true, then I suggest cutting enough of the plastic fuselage away in order to perform a good glue job to secure the fin to the stab.

A repair of the newly created "access slot" can be done by gluing a piece of material over the breach.

Pay very close attention to the WEIGHT of all materials used on this repair, in order to avoid adding a ton of weight up front in order to regain balance.

After the repair is complete, check the balance. Good Luck

Oh Ok where the vertical stab (v stab) is attached to the fueslage (fuse)?? Use a flux brush (small metal brush with bristles available at the local Hardware store) and apply some 30 minute epoxy around the edges on both sides. Any other way would require carefully cutting the Vertical Stab off and re-applying the epoxy. Other's might suggest removing it but I have had good look by using the 30 minute epoxy without having to cut it off. 30 minute epoxy is strong stuff. Try and force as much as you can in between the fuse and the v Stab. Be sure to check your 90 degree aligement. You want to check it every few minutes while the epoxy cures. After 30 minutes it will be set and no adjustments will be able to be made. Any excess epoxy can be removed with rubbing alcohol prior to it setting up. From what you have described this method should work for you.

I had the H9 cherokee as a 2nd plane and flew great. I didn't like how both the horizontal stab and vertical fin mounted in the molded formed fuseladge. The vertical and horizontal stabs didn't come out totally correct, but it still flew fine.

OK, so i was able to remove the rudder (vertical stabilizer from the fuselage, now the wood has some epoxy on it, i tried to remove it but it will damage the wood. Can i glue over the epoxy on the wood and will it hold.


Thanks

i built the same plane, on mine the top half of the fuse. was not glued to the horizontal stab. witch let the vertical stab. move glued it everywhere i could get glue in wiped it of with some alcohol . worked great. i still had to add 1 1/2 oz. of weight to tail fly great and is very fast. the rudder is the part of the vertical stab. that moves . good luck lee p. s. i think this a good plane for 100 bucks

I agree,it is a Nice Plane for 100 bucks,and with AFRs you know your going to have too do some touch up work your self,i was looking at the H9 and the GP Cherokee as a winter Project,but i opted too get the GP version,im about 50% done now,and i Glued the horizontal stab and the vertical stab during the Build as Protected measures.

I just hope i dont have too take them off,casue i dont think there going too now!!!! [X(]

OK.. sanded the glue. until it was smooth, glued everything back in place. Looks good so far.. i used 30min epoxy, will wait till tomorrow until its all solid and firm, and hopefully it will fly again in a good shape. Thanks eastcost for your help and reelay,, your plane looks amazing great job putting it all together.. this is my second plane, and i had some hard time with the windows and all that plastic.. but looks good and i am learning.. thank you all for your advice.. and will keep you posted on the next flight test. I have a 52 evolution engine in mine and on its test flight it was really fast and made very nice rolls and loops .. wish me luck and thanks again.

ahh good too hear,
did you balance your Plane too see if its still got a good COG,,you don't want too get airborne and the COG be off,you well not be happy!![] im sure the glue well hold it in Place though,if you don't have a COG tool ,Ive heard of ppl using there fingers,just get the Spec's on where the COG Points are from the leading edge of the Wing,and mark it with some Low stick Tape , get someone too hold the Plane up side down(cause its a Low Wing) and lay it on your fingers where you marked it with tape,it'll give you abit of an idea if its tail heavy or visa versa
