I have seen several post lately on this issue and just thought I would chime in and give my opinion.
Fiberglass tubes are more durable and a little heavier than carbon. Fiberglass is what has typically been used on most bro approved slabs. When I designed the 46" UL Slick I decided to use carbon because I was trying to shave off every ounce possible. I have used Carbon in both of my Slick designs and it has worked very well with no failures that I know of.
I think on any light weight designs carbon is the way to go. If you break a carbon tube in a lightweight profile it will more than likely be destroyed beyond repair. As far as Mojo's, Primo's and any other more standard weight slabs, I agree that fiberglass is the way to go.
thanks Doug--good to hear from you and my slick is still the slickest and sickest plane at the park.
Now we just need someone to weigh in with where to find .505 tubes and whatever for things being currently kitted at a good price. Has anyone found a good deal lately?
Thanks! I saw that site in the other thread, but looked for "fiberglass" instead of "epoxy". That's a good price, but the shipping is (understandably) twice the item price. I'm going to look around, but might have to just eat it.

Think ahead if you decide to order. I notice the shipping is the same for multiple tubes or one. I tried three tubes and shipping didn't change. Still flat 15 bucks.

ya I noticed that, too. now if I could just predict what 3 or 4 kits I am going to build from plans or short kits soon. I think I know at least a couple.
From my experience,the fiber glass bends then the frame rails break,no big deal just re-glue,patch go fly.But with carbon there is no flex.I guess either way your going to need some sort of repair if you hit hard enough to flex a fiber glass tube.

i use walmart arrow shafts in my small stuff. been using carbon in my lamyaks. of course, i don't pile them in much like i did when learning backwards rudder stuff. at 2.5 lb. the carbon plenty strong. bought several 12mm from hk a whilr back.
Thanks sparkplug.
As pictured there with no gear it is 10.95 oz.
I'm not the lightest builder out there, but I think that is in the ballpark of the 36" wingspan birds.
A quick guesstimate of the gear weight puts it at around 20 oz RTF wight.
Gear:
Savox 1/2 oz weight digital servo's - metal gear (4).
Graupner RX
ST .10 Motor.
Castle Talon 35 Speedo
Thanks guys
When I built it I put a Mojo style top and canopy on it - almost identical to my Mojo 25 in my avitar. The original Skeeter is a lot more straight. So I call it a MoSkeeter

say it again,skeeter looks good.was that a kit or plans,i looked at pics 3 times,bet its going to fly sweet.be nice to have one.what power system are you planing to use.im new to el planes,but impressed.
I just finished a MoAss60,if I would have used a 1/2" carbon tube it wouldn't be as tail heavy as with the .602 fiberglass.Also the 1/2" tube makes it much easier to build,no cutting in the larger fiberglass.It just balances at 7-1/4" with a DLE20,2500 a123 in the leading edge.
My next 60 kit from Sam will have a 1/2" carbon,just to see what the difference is.
You have polnt,it adds up,i be learning,thats what gets one on small planes,tubes do make strong,glass for bigger planes gives flex thats needed,so much mass got to give or snap. Wf 2 piece tail give good place to snap,carbon might work well if joint not to strong,save few oz maybe.

:thinking: :thinking: :thinking: I'd keep it Fiberglass as designed.. Fiberglass on this size bird is MUCH more forgiving. CF will shatter on a minor dork, then you'll have lots of repairs - if it's repairable.
