Okay, good day everybody!!!

Yes i know i'm not to fast building my plane but at least it's build up the right way.... it's funny i bought it in february lol

I had a problem when i got my plane cauz i had a crooked or bent aileron... so i contacted Horizon Hobby and they did not fool around with me they decided to send me a new wing set for my airplane.

But!!! there is a difference in between the two of them! lolll Always something.... and spring is here and i want to go try it! GRRR

There is a pre-made hole for the ailerons servo in the middle of the original wing set. The new wing set has a hole too, but it's only on one side... so not centered. I was thinking that the connecting rods will be attached strangely to the servos.... am i right or not?

here is some picture that might explain more :P lol

thank you!

How are the wings joined on this plane? Do you epoxy them or are the held in place with screws. If you don't have the original wing permenantly joined I would just use the good half from the first wing with the other half from the replacement wing. It looks like the hole is missing on the same half that is good from your old wing. Just mix and match the wing halves and you should be ok.

Ken

i cant! they dont have the same type of wing jonctions.... both of them are not epoxieds together yet.

i'll show you pictures.

but the servo fit in the hole of the new wing set... the only thing is that the rods wont be too too parallel

here is the picture

Don't sweat it. That's the new way they are doing it and it works just fine.

As Minn says, "Don't sweat it." I am training a guy at my feild on one of these right now and it has the offset servo like your new wing. While the connecting rods are canted to the side the plane flys great. It may not be perfect geometry for identical movement of both ailerons but your not going to enter a pattern aerobatics competition with it either. On a side note ensure you use locktight on the screws for the front gear. After my student's third flight last Saturday his nose gear almost fell off and two of the blind nuts fell back into the fuel cell bay. We wasted about 2 hours getting it back together and we could have had about 3 more flights instead.

okay thanks! but if i put some threadlock on that screw for the nose gear then i wont be able to remove it later for somewhat reason though?

BTW what does that means that expression: Dont sweat it? sorry i come from quebec i am bilingual but do not understand all your expressions

thanks

Marcus,
As Minn and Stang have said, you'll be fine with the new wing. Just set up the new servo in the new location.

As far as your nosewheel goes. If you use thread lock make sure you use the blue thread lock, not the red. Red Loctite is permenant you you'll never get the parts apart again.

Ken

"Dont sweat it." = Do not worry about it.
The thread lock is sold in two types. One is a semi perminent (Red) and the other is a temporary (Blue)... use the blue stuff.

Blue thread loc dries like old chewing gum, so it CAN be removed, but vibrations alone won't do it.

"Don't sweat it" means not to worry. When you're really worried, you sweat (Perspire). So it just means, "Don't get all worked up over it"

Good that you cleared that up!!!! I was afraid that you meant something that had to do with Richard Simmons!!!!! [:'(][:'(]




Ken

Three guys typing at the same time and as usual Ken gets in there first... I think he has every response already typed and just cuts and paste it in when apropriate

Shhhh, don't give away all my secrets!!!!!!!

Ken

thank you guys.... ohh Stang i wanted to ask... since i will join my two wings together (the new ones) it's the model with that aluminium bar that goes in both wings as a guide... do i put epoxy on that shaft and then i slide it in my wings and thats it?

thanks

Marcus

I recomend taking some course grit sand paper such as 80 - 100 grit and roughing up the aluminium shaft, then yes smear epoxy on the shaft and get some in the holes that it goes into. Remember just rough the surface of the shaft as you do not want to make it smaller. This gives some texture for the epoxy to adhear to. make sure you also put epoxy on the root ribs and the guide pin near the trailing edge. Have a bottle of rubbing alcohol and a rag/paper towels near by. to wipe of the excess epoxy that will squeeze out between the joint. Using 30 minute epoxy gives you the most time to adjust things. I will admit the last one I did (for my current student) I used 15 minute, however the 30 minute will soak into the wood better and give you a better bond.

Make sure you tell us how the maiden flight goes.

I finished putting my daughter's Alpha 40 through it's paces last weekend.

It had the offset servo, and I really could not notice it.

The maximum movement of the ailerons is so low, that you will not have problems with the linkage that way.


I also did exactly as Mr67Stang mentioned in his post.

After it dried I then applied the included tape for completeness.

I would also add that if you are going to use the rubber bands, that you may want to get some "saddle tape" for the wing roots to avoid damaging the wing.

The offset servo techniques have been used in many planes over the years with no problems.

On another note, I find it odd that Ken had Richard Simmons on his mind.

i will glue my two wings together tomorrow. OPJOSE was talking about some tape for completeness.... where does that tape goes? I guess it's to eliminate the little gap in between the wings right?

when you said : "I would also add that if you are going to use the rubber bands, that you may want to get some "saddle tape" for the wing roots to avoid damaging the wing."

sorry but i do not understand this part.... saddle tape .... dont know that either... my god, i wish i could understand all those words.

is it this?


and where would you put it?


thanks again

That's the right tape but it's discontinued at Tower. May be able to find it elsewhere. Here's something in stock at Tower just in case.

The other tape mentioned should just be a vinyl tape that is included in the kit that wraps around the wing root to cover the gap that may exist. 99% appearance.

Yeap.


Tower has this stuff in stock which you can cut down as needed.

The wing "sits" on the two vertical portions of the fuselage.

When the rubber bands are applied, the wing and the fuselage contact each other exactly where you want to put the tape.

Place the tape on the fuselage side, not the wing. The tape is single sided sticky tape, so it will adhere to the fuselage "walls" right on the edge.

It has two effects.

1 - It prevents damage to the wing and covering.
2 - It helps to prevent having the wing move or slide while in flight.

I put it on my daughter's trainer and the wing does not shift in flight as some have reported.

Like others have said, they build these planes with the servo on one wing, to make assembly easier. All you have to do is join the wing halves and attach one clevis.

I maidened mine last weekend, and on my first landing (second flight) I came down a little hard on the nose gear and the firewall popped out about 2/3 of the way. I made a new firewall and epoxied it back in with tri-stock reinforcement. The guys at the field were surprised that it came apart, it really wasn't that hard of a landing. You may want to reinforce your firewall with tri-stock just in case. I hear this is a good idea for any ARF.


Good luck.

This is actually very important. Thank you mclina. I was unaware that the Alphas had this problem but it seems Hangar 9 is having some quality control issues as I have a FuntanaX 100 and a 60 size Spitfire that have had glue joint failure proplems. see my thread in the Crash and Rebuild section titled "ARFrustration FuntanaX 100" I have some pictures in there.

Deffinately reinforce vital joints with extra glue and Triangle stock.
