Status: offline 		Just got signed off a few weeks ago.  Pretty new to the hobbie and love it. I bought a big stick 40 with a os 46 ax. Is there anything special I need to know about before I start on my plane. I been flying a rtf alpha 40. My building experence is very limited.
                                                                                                            thanks Bill

Status: offline 		The Great Planes ARFs have good instructions. As long as you follow them closely, you'll have a nice flying plane. Be sure the balance is in range before the first flight, and it won't hurt anything to get one of your club's more experienced builders to check it over.

Status: offline 		make sure to take your time and get the wing center-section epoxied as per the instructions, 30 min epoxy, and double and even triple check the alignment, before you glue an clamp.

I still get nervous, not having any glas fibre taped around the centresection. I used a large T pin, and poked holes through, both sides to create " nails" to hold extra strenghth.

Like racerchuck mentioned.


The center section where the wings join. I
reinforced mine, it's flying in it's 3rd season.

Enjoy,

Status: offline 		Also harden the wooden front wing retention "pin" ( It's not really a PIN in this case, it's the little wooden protrusion ).... with CA.

Apply thin CA liberally to that area to harden the wood and let it dry for a while.

Status: offline 		I have a Big Stik 40 with an OS 46ax in it.  Mine came out very nose heavy.  I ended up cutting a door in the bottom of the plane towards the back and put the radio battery way back there.  It still took a couple ounces of additional lead with the battery to make the plane balance.  I also moved the engine as far back in the mounts as I could.  She is a great flier.  This was my second plane and I think it is easier to fly then my trainer was.  It is also very good in the wind.  If I was going to build another one I think I would try to move the elevator and rudder servos to the back of the plane and make it a tail dragger.

It is also very good in the wind. 



You said it!

The only time I cannot haul my .60 out in high winds, is because the wind speed is so high, the plane will not remain on the ground, even when weighted down.

Anything short of that, and I can fly....

Status: offline 		As has been said, GP arf's are pretty good.
I'd be hesitant to harden the leading edge retention "pin" with CA glue. This also makes it brittle.

Perhaps a bit of thin cotton wrap and a touch of wood glue to seal it is good. But anything that makes a high stress area brittle should be avoided. That retention pin sees a lot of vibration so keep the reinforcement on the absorbing side.

Other than that, reinforce some of the joints in the wing box area with some white wood glue. Just a light run over the current joints will be sufficient to add some strenght and vibration damping. Leave over night to cure.

then build toinstructions and go fly. GP arf's are that easy.

Status: offline 		Sticks are wonderful airplanes to fly. You can go as mild or wild as you want. Be aware they are notoriously nose heavy, so don't be afraid to add a little lead in the tail to balance. Then go fly the snot out of it. Picture of a stick on a bad day and a stick on a good day.

The LE retention pin is hardwood.

CA does not tend to soak through it completely as it may with balsa, leading to a potential shear line as you've indicated.

CA in this case tends to coat the surfaces, helping to prevent wear.

With over 400+ VERY HARD flying flights on my .60, there is no indication of wear or brittle characteristics.

so, a friend of mine has a composite shop and he made me some thick wall .375 inch carbon dowels, 2.25 inches long that were epoxied into the leading edge.  End of problem.

Status: offline 		I've had a Big Stik 40 ARF for a while and it's my go-to plane. It's the model that i always take to the field.

There's a reason why the basic stick design has remained unchanged for 40 odd years and why they are still sold today. To put it simply they fly great.

I converted mine to a tail dragger and put an OS .72 4-stroke up front. It flew great but was nose heavy and needed a lot of lead in the tail to balance.
I pulled out the 4-stroke and put a slightly lighter Enya .61 2-stroke up front which also allowed me to mount the engine 3/8" back and take out some of the lead from the tail but i still have 1.5oz back there.

I'm seriously thinking about putting my Enya .46 up front because it weighs 3oz less and i should be able to take all of the lead from the tail which would give me an even better flying model.

Status: offline 		I have had a number of GP 40-sized Stiks over the years, both kit-built and ARF. All had a 46, OS-SF/OS-AX/Magnum up front and all needed an ounce or two in the tail. And they all flew with authority, not unlimited vertical, mind you, but with authority. As for why I've had to have several, well, the planes didn't have thumbs, I did, and therein lies the answer.

That doesn't look like a GP Big Stik though.

Not in the area where you had that problem though.

The GP Stiks use the hardwood wing root former to make up the left and right halfs of the single "peg" that goes into the slot on the fuselage former.

In the prior images you can see that slot at the top of the rectangular former cutout in the innter fuselage view, forward of the landing gear mounts.

Once the two halves are epoxied together, and a bit of CA is applied for hardening, you end up with a pretty strong arrangement that has held up well to the heavy handed aerial beatings I give mine.

I've seen a post where someone complained about the wear this area gets, but IMHO applying CA did the trick for mine.

I just wanted to make this clear to anyone following along, "playing the home game"...

Status: offline 		I just built ( assembled ) a Big Stik 40 ARF and put an OS 46ax on it , like yours . I mounted my 46
on it's side so all the goo would be expelled under the plane . I had read that the Great Planes ARF
was nose heavy , so I put the battery behind the servos and converted it to a tail dragger ( better
on our rough grass field also) . I also put a Macs black muffler on the engine saving 2 oz. up front .
The plane balanced at the front of the range . My copy came with half the wing mount pin broken .
I had to epoxy it together and then epoxy coated the entire pin . I had to widen the slot in the body
to accept the widened pin .
It flies very well , but is definitely not over powered . A more powerful engine , especially a 4 stroke
would be more fun to fly ( more vertical ) but I am trying to use my 2 strokes on planes that will get
less goo on them , and are easy to clean . It is also important to keep weight off of the nose , and my
2 strokes are lighter . It has the best ground handling of all my aircraft so far .
