I saw these at tower and they look like they are exactly what i need. This is replacement for a 4star?

i dont see why they wouldnt work. why arent you using the ones that came with the plane?

They go CA in them. I was thinking though, I could easily bend some out of pushrod...

Just clean the CA of the originals

bubba,
I would have done that, but i am almost positive they accidently got thrown away..[:@]

The torque rods on my trainer, and the ones on my Astro Hog, are thicker than normal pushrod wire. They have either 4-40 or 6-32 threads where the adjusters are and the wire is as thick as a #4 or #6 bolt. I'd spend the few dollars and know I had the right stuff.

ok so will these dubro ones work?

Why don't you convert over to dual servo's and eliminate the torque arm altogether.

I thought you HAD gone the dual servo route....

and those Dubros look just fine....

I also thought you said you had broken your torque rods (please note correct spelling) while bending them for some reason?

Yes exeter_acres, he had gone the dual aileron servo route but that was a few days ago. Things change quickly with some.

"I could easily bend some out" --- Something that bends easily will un-bend just as easy. Do you want that for a control?[:@]

Hi!
They will do...pianowire seems to be around 3mm in diameter..but a better choice is the Du-Bro heavy duty aileron set with 1/8" pianowire in a plastic hose, safer and easier to CA glue them in then the ones you have shown with a single nylon attachment.
I have been using those heavy duty Du-Bro linkages in all my .40 Q-500 pylon racers for years.

Torque rods are an invitation to flutter on larger models. The spring action will resonate at some frequency and, if your model hits that point, flutter results.

This is only a 40 sized model. I do not want to do dual aileron. It is a little hard to make...

Also, the dual ailerons didn't work too well last time, so i want to do these as the instructions suggest..


Jan,
Those will work. I was iffy about the ones that screwed in also, so i will purchase those.

Thanks guys (and girls)

I figured out what i need..

they aren't hard to make at all. You just have to have patience. Dual ailerons are the easiest mod on any kit. Again, as I said before, if you've already glued the block onto the TE that holds the torque rods on, you'll have even more modifying to do. Doesn't the four star use full length strip ailerons? If so, all you have to do it set two servos side by side . Just enlarge the opening for your single servo a little. You may have to add some additional hardwood for support underneath, but this shouldn't be a problem at all--a five minute job, MAX. Set two servos side by side with control horns protruding opposite of each other. Connect push rods from the servo to a plastic control horn on the aileron, and you're set.

Chad,
These are just as easy to bend as z-bends are, if not easier.

While mowing the yard today, my mom picked up the antenna and the tourque rods. Ken, I Bent some last night, but they were very flemsy using Sig's pushrods and figured to be safe, so i didn't install them. I don't want to have to mess with all the cords of fual servos and such, but who knows i might find the need for them later. I am just glad i am getting this thing done slowly but surely. Next up is putting on the wing bolts.. and also covering.

There are no extra "cords." Connect your two servos together using a Y. Then, plug your Y into your aileron extension just as you would if you had a single servo setup. easy as pie...

Pilot Chad

My Feedback: (4)

oh well.. too late not. Also, i don't think it would work the way you states, because you need to somehow get you rods out of the fuse... I just don't see the need. I will be fine with single aileron servo for a good amount of time. And i would nee to buy 2 more servos since i had one give up on me the other day..

I have read your build thread. I know you're trying to recover from some mistakes and that you're on a tight budget. I think getting the Dubro part listed above and doing the single servo installation as close as possible to the original instructions is your best approach.

I'm not an expert builder, I make plenty of mistakes. Since this is your first kit I just think sticking as close as possible to the manual will give you the best chance to have a successful build. My first was the PT-60 in my avatar. I was worried it would fly like a corkscrew. It actually took very little trimming to fly straight and level. My second (current) build is an Uproar 60. I can see some mistakes and hope they are just 'cosmetic.' I'll have it checked over by a very experienced builder/pilot before it goes up.

Carrell,
an experienced pilot will look it over and Maiden. I think about a 50 dollar order to tower is in my future. I need 2 rolls of covering, a servo, and a heat gun, and then i think i am ready to fly this thing. I can already do laps around the field with my ugly stick.

When I wrote "I can see some mistakes........." I was referring to my Uproar. Ithink you've corrected, or are working on, everything that has been pointed out.

After I glued the fuselage sides firmly to the formers I noticed one side is curved slightly more than the other. I know that means it is not perfectly straight. I asked the person who will be doing the inspection about it and he told me to let him look at it. He said it should be minor enough to have little impact so I've continued. I've made a few more errors too. Hopefully they will not add up to a poor flying plane. I'm doing the best I can and that's all any of us can do.

I made a lot of mistakes on the PT-60 too. In some areas it looked like a 4 year old fingerpainted on it with CA. My instructor looked it over and said "Structurally it is fine. Just sand down the really high spots, throw some lightweight filler on it, and sand it smooth. Then cover it and the mistake is gone." I knocked a hole in the wing sheeting and asked if I needed to resheet. He told me to press the broken part flat from the inside and glue a backer piece inside to keep it flat.

I know you've replaced some wing parts and remounted your engine. I doubt the epoxy on the fuselage formers will have a huge impact unless it's really pooled up on the wood. If there's just enough to make a solid joint you probably didn't add a significant amount of weight.

We all want our projects to be 'perfect' but that's not likely to happen. Luckily it seems model airplane can be far from perfect and still fly really well.

Yep, I thought this one would be my baby. But i think i will get about a 60 size extra for it sooner or later and TAKE MY TIME on it.
