new/ old plane what is it?
 

My buddy picked this up for $25. Im not sure what plane it is. Do any of you guys know? the wingspan is about 84'. What size motor would be needed for this? also servos. 4 channel ?

RE: new/ old plane what is it?
 

Well, it is a low-wing Stik. That much I can tell you but not sure what kit it is from or if it is scratch built or what. Definitely a 4-channel airplane. If I had it, I would be putting a small gasoline engine on it. Maybe something in the 26-30cc range? I guess that also depends on the weight.

RE: new/ old plane what is it?
 

Not sure what it is, but with a 84' wingspan a big big motor will be needed:D:D. Some pretty strong servos too!

Hi

Might be a Midwest Giant Sweet and Low stik. looks a lot like one.

G-38 would fit nicely.

I would X2 on the Giant Sweet N Low guess.

Good deal for 25? How many ounces on the servos

RE: new/ old plane what is it?
 

It looks like a pretty good deal at $25. For servos, it really depends on how he plans on flying it, but for most applications, something in the 70 oz/in range should be sufficient. I would not use standard torque (40-45 oz/in) on it just because of size. A 90 size 2-stroke or a 120 4-stroke would probably fly it decently.

RE: new/ old plane what is it?
 

Those are 17lb's with a 84" wing span.

RE: new/ old plane what is it?
 

Ditto:D Should be a very good flying plane.

RE: new/ old plane what is it?
 

My rule of thumb is 80 inches gets a 40cc gas engine or there abouts. Weight would also mater. Today we have some very good gas engines that would work from 30 to about 40cc. There are some good glow engines that work too but with the cost of glow fuel I make the cut off at 1.20 then go gas. I can't see the wing bottom to be sure if it is four or five channels. Is it one or two aileron servos? I would be looking at servos from about 70 to 100 inch pounds. Not a bad looking Stick.

RE: new/ old plane what is it?
 

if i recal right the aileron and elevators use one servo each. so for the aileron it would probley need a pretty hefty servo correct? thanks for all the input to its appreciated.

RE: new/ old plane what is it?
 

That's a Midwest Giant Sweet N Low! It uses standard servos,1 on each aileron,rudder,and 2 coupled together for the stab. I had one for years,and flew it with a Quadra 42. They are great flying planes,and the CG is located Dead on the Main Spar.Mine came in fueled up and taxiing down the runway at 18 pounds. With the newer engines out there now,you can pretty much use any 30 cc and up on it.

Hope this info help's you out!

P.S. GREAT BUY!

RE: new/ old plane what is it?
 

thanks abacro, that will help out greatly, although what is the stab? the elevator?

RE: new/ old plane what is it?
 

I suspect what was ment is that the elevators are split and one servo each elevator surface is used.

That stick goes back many years and folks tended to use 'standard' servos however this was at a time when there really was nothing else avaliable. In these times it would be appropriate to use servos with at least some improvement over the old 'standards' which were slow and around 40 ounce/inch. There are many fine medium performance servos now that are the same size and won,t break the bank.

The stab is the elevator,yes. And John,on the Midwest Sweet N Low,the elevator was not a two piece,the halves were joined together by a 4/40 piece of music wire,and one clevis controled both sides. The plans showed a single control rod running from two servos,couple together in the fuse.I used that set up for years,till i finely replaced the 2 standard servos with a single giant scale high torque one.


Good luck,and good flying

RE: new/ old plane what is it?
 

Great Art that clears that up as I never had that airplane. So what I would reccomend to the original poster is to use a single servo on the elevator a more modern servo with more power rather than ganging two low powered servos on one pushrod.

When ganging servos on the same surface often one will be working harder than the other and battery consumption will be greater.

I sure hope your buddy knows. If not then he better go out to a local field/club and get some help in the way of an instructor so he can learn both flying and set up before he tries to go it alone. The plane may only cost $25.00 but the rest of the gear to get it off the ground can put it about $650.00. Someone in the know should look the plane over before any money goes into it. The air frame is old and may need repairs, an instructor can check things out before there is more money put into the plane and inform your friend exactly what he will need to make it air worthy again. They don't get better with age. Glue joints dry out, wood gets oil soaked and covering gets brittle. Tell your friend to find help before he goes any farther with it.;)

RE: new/ old plane what is it?
 

i have a flight sim im going to let him practice on, as for covering it feels more like nylon now. is it suppose to be like that or is it suppose to be a plastic feel? i know fresh monokote is a lot more shiny and plastic feeling, but after age does it dull out and turn more nylon fabric feeling?

RE: new/ old plane what is it?
 

I agree it looks like the Midwest stick. Even a 35 gasser would fly it nice. He could then use a "Metal Gear" servo on the surfaces and it would fly just fine. My Davis D1W 116 inch WS has a old Quadra 35 gas flying it at 24 pounds. It sets no speed records but it flies nice. I use Metal Gear standard servos and have no problems. Standard servos can easily move large surfaces as long as the airplane is not flying real fast. Because the speed over the surface is not as great.

The question then becomes. Does the owner want a overpowered crazy airplane on the verge of uncontrolable or a sweet flying plane.

$25.00 for that plane is a deal. I would have not even hesitated at that price. If the covering feels like nylon it might be something like coverite.

RE: new/ old plane what is it?
 

No it does not.

There were many options for covering all contemperary with this airplane and the bottom line is any of them could have been used. If so, many will not be airworthy either at this late date. Its totally impossible try and identify what it is over the internet. You need to have the airplane looked over by an experinced builder flyer and the best place for him to do that is at his local club.

OK now when Gray Beard suggested he find help before proceeding any further you responded with "i have a flight sim im going to let him practice on". Hmmmm boy does that set off the red flags!

Does that mean you are going to buddy box him? Forgive me but that takes considerable skill and training in itself to do properly and that just seemed unlikely due to the nature of your questions and it seems boats is your main activity.

If he goes off alone somewhere with no experiance save for simulator time that airplane is going to be a big smoking hole with a totol loss of an expensive large gasser engine as well as the electronics. That 25 dollar bargain then won,t feel like such a deal.

Do your friend a favor if he really is a friend and insist he find experianced mentorship and thats usually at a club. Ya,ya I know the evil club word thats if ya really want to be a friend to him!


John

RE: new/ old plane what is it?
 

Lol well I respect your opinion. Boats was my main reason I joined rcu a while ago. Personally I prefer jelicopyers. I have a .50 raptor. The purpose of the sim is to let him see what he is getting into first of all. If he still wants to continue I told him he will need to strip the skin and apply a new one. There is an rc air field around here somewhere that he knows of. planes really aren't my thing unless its a foamy rtf that I won't mind losing but a plane of that size wouldn't personally want. I would how ever build one for a static display. but all in all if Jw wants to continue pursuing the plane after the sim ill help him out and get it set up right and help him find a club.

RE: new/ old plane what is it?
 

If it's not fuel soaked I would put an AXI 5330 electric motor in it.....after doing everything possible to make it lighter. (I'm anticipating howls of protest from glow & gas flyers). A 10S Lipo would make it heavy really quick.

The attached 4Star 120 has an 81" wingspan and an AXI 5330, which is the equivalent of a 1.20 - 1.60. Hasn't flown yet.

RE: new/ old plane what is it?
 

Now you are talking TW, Kudos

John;)

RE: new/ old plane what is it?
 

Ok, you got your answer, now pick up your cloths and make that bed!

RE: new/ old plane what is it?
 

John I disagree. I have an Aeromaster Biplane that is 35 years old. It flies just fine and glue joints are still secure. It was done with silk and dope in 1975. If the Covering is still secure, no holes, it could fly. I would do what I call a pinch test. Go over areas of the plane and give it a gentle squeeze. If everything is still strong there should be no problems. Look in the fuselage and take a dowel or screwdriver and just push gently on the formers. If they are not loose then the fuselage is still strong and secure. Planes are easy to check for airworthinss. All you have to do is take a few minutes to check. Pull on the control surfaces and make sure they are still securely attached. If it passes all that, then I put an engine on the firewall and push and pull on that. If it holds then it will be fine. If there is cracking then I mix up some epoxy and reglue it inside and out.

The OP is in the Detroit area their is lots of clubs down there. I recommend contacting a LHS and get some local club info. or go to the AMA website. Someone would be more than happy to help him. There is many good people down there. I bet he could even get flight training.
