True,

Aluminum should be used rather then carbon for that reason. I mentioned carbon because there a number of machines that used carbon for torque tubes that many are still flying.

I prefer aluminum myself, espcially after seeing one in a ship after the tail blades had conctacted the grass a little to hard.

Torue tubes

here is another way that a guy just told me of :
"i received alot of mouth on how i make them, but they work great for me. i have used my torque tubes in my xcells and now have one in my pred. gas condor. i have never had a failure. my torque tubes cost me a grand total of about $4.00. go to auto zone or a car parts store and get 1/4 inch stainless steel brake line. LOOK AT IT TO MAKE SURE IT IS STRAIGHT! some of them come in a package. cut to size on the pred. i have to drill out the dog bones (the fittings on the end of the torque tube), take out the pin on the dog bone. slide the dog bone on the torque tube, JB weld it on, drill a hole through where the pin came out of. do that on both ends and your ready to roll. if you have any spare dog bones or bearing i could use those."

so if you dont like tharrow idea try this one.

only you have the power to make no difference!

Thanks eyeflyhelis,
Would there be a way to reuse the dog bones, ie: apply small amount of heat to release adhesive and drive pin out. These are usually in good shape and it would be nice to reuse. I wonder if using blue or red loctite (mcfast used blue loctite) would be easier getting off?? Just an idea. Ill try the brake line idea, sounds like it would work as long as its staight. Thanks for the
info !! Darren

Hi 7379df
You could use "HOT GLUE" it would hold pretty good and come off easy with a bit of heat.

i dont think the type of glue is important as long as the pin is put back in. i believe the glue just stiffens up and prevents the dog bone from moving on the pin

I think it is important the type of glue we use, it should be some thing that is easy to repair, lets say you just wont to change the bearing and you can not get the end off, if you use some thing like "JB weld" that could happen, then you end up changing ever thing and it will cost a lot more,

Another thing guys, the little plastic "holders", to hold the bearings in place, I would assume cannot be purchased seperately
or can they ? I know the bearings can be replaced. Of course, if
taken care of, these could outlast the bearings. I have 4 total,
2 in heli and 2 spares. Im going to call our local bearing supplier
and order some Xtra bearings. One more thing, what type of glue is
everybody using on these bearing retainers, holders, whatever you
call them, sure would be nice to get those to come off easier when
changing the torque tube out. Thanks for the replies. Darren

slz,
The main reason i even looked into this is because everywhere i checked the boom (855mm) was on back order. And nobody could tell me when it was due in. This is what led up to this whole thing. I didnt want to wait weeks on a part to come in when it would be fairly easy to fabricate if the correct materials were found. So thats when I stumbled across a piece of left over pipe in my shop that happened to be exactly 21mm and it was from a broom.

I am currently documenting this and will send pictures later
of how i made the boom for anyone interested. At this point the boom is already attached to both ends and it fits like a glove. I have ran the heli, no blades, low to mid rpm and everything seems to work thus far. But I want to make sure it flys before sending pics and info.

At this point I have no idea if the heli will even fly properly. I am just taking it one step at a time. Currently still waiting for blades ect. to come in before i test fly. IF it does fly and works properly,(ie, no vibrations, ect.) I will send the pictures of the parts i used and the details for anyone interested. In case this doesnt work I would like to know if there is other places besides Ricks and Heli world that might have tail boom and torque tube in stock? (must be 855mm) In the mean time i will keep trying. Also, it is kinda fun makin stuff from scratch, especially if it works. Later, Darren

Well, I finally got some pictures of the "broom handle boom". Also got to start it up and very low hover in shop(Dont try that at home).
Absolutely no vibrations or ANY problems with tail, in fact the tail works better than old one. I know this does NOT prove that it works 100%, but I will be flying next few days, weather permitting and will keep posting. Here's some pics of boom with a lacquer
finish on it, O'yea, and Daddys little heli girl. Thanks Darren

i know some of ya'll dog bones are glued/pinned to the ends of the TTube.

Bergen uses easton arrow shafts in their Intrpids. drill a dimple/flat on the dogbone, slip into the shaft, drill 1 hole thru shaft big enough for a set screw and mate it to the previous flat/dimple. Get a wheel collar that has 4 setscrews around it, and slip it over the shaft. One set screw goes all the way through everything to the flat/dimple on the dogbone.

No glue very secure mount system.
