How are pushrods mounted on a profile...flex cables/solid...inside/outside......???

Also, since the rudder servo is in the wing, how are pull pull systems set up. Do the cables just run the whole length of the fuse on the outside or is there another way? Plz help

I use carbon fibre arrow shafts. I glue in wooden dowel in the ends and drill for 2-56 threaded rod which I CA in. Haven't had one fail yet. Looks trick, is light and strong - I shoot archery and between me occassionally breaking an arrow (shatter the tip hitting rocks - yah, I know, you're supposed to hit the target) and picking other peoples damaged arrows out of the trash at the end of tournaments I have plenty! Check out indoor archery ranges - sometimes you'll be able to scrounge broken arrows there too...

That is a great idea with the arrow shafts !!!

I have two profiles the morris sledge and the OMP edge

The edge usees 2-56 rods that are about 3" and 5" with the servos mounted in the tail.

The sledge uses pull-pull cables that run inside tubes glued inside the fuselage.

i seen may pull pull set ups in pictures but very hard to see how its done. As of now I am using those nasty Sullivan red rods....i hate them but thats what it came with so i used them...

I do have 2 packs of those black fiber glass push rods and was thinking about putting my Sullivan inside of them. the fit perfect now just need a clamp to attach rod to fuse. One idea there

But about the pull pull.. how do you guys set them up... do you run the 2 wires side by side into a rod? If so how does the rod hold up where the wires go in at?

Can any one post pics of their pushrod/pull pull set ups? Need some close up visual aids.

Here's how I did it on my first Taco:

The tail setup:

Here the other side of the tail

okay so what do the pull pull do inside the fuse? If I would have thought about it before covering I would have put inside also.

Do you have a small rod or something that they run through inside fuse or a metal round eye or something to keep wires close together? I am trying to figure a way to make mine work out outside of fuse.

heres how you can do it with 30"rods, I use nylon LG straps to hold them onto the fuse, 2 per side, I also try to line them up so they are directly across from each other on opposite sides of the fuse

I use the push rods and LG straps now too... But if you wanna do pull-pull outside the fuse.. You can use the LG straps and short pieces of antena tubing or inner nyrod to act as guides for the pull pull cables. You'll have to cross drill the fuse for the rudder and insert a tube into the hole..

Bought a digital camera yesterday. This is a good excuse to post some pix... CF pushrods on my new profile fuselage Something Extra:

Hey Daryl why two mufflers if I can ask?

Dream_Flyer - at our field noise is an issue and we have a 93Db limit on engines below 1 Cube and 96 for 1 Cube and over. This is measured over grass at full throttle from all four quadrants from the standard distance (can't remember right now if it's 2 metres or 3 - just got up!). Meeting this limit is tough for smaller engines that spin up higher RPMs and tougher for bigger engines. .60s seem the easiest to quieten down, especially long stroke/high torque designs that can lug a bigger prop. An efficient mufflering system and reduced diameter high pitch props to minimise prop tip speed are the trick. The Wasp is shockingly quiet - when people from other clubs see/hear it for the first time they are astounded. On the other thread re my profile fun fly plane using Sig Something Extra wings and tailfeathers, you'll see I have an O.S. .61 FSR with the stock muffler modified with a Dubro Arise muffler and then have an after muffler attached. Doesn't seem to hurt performance too much and sure quiets things down. I'm transferred to Winnipeg shortly where noise isn't as much (if any!) concern at their fields. I do prefer quieter planes though - I just find it less stressful/more pleasing. I think this is part of the reason why 4 strokes have taken off the way they have, but to my way of thinking they have all those extra parts... :^) Here's how I make those after mufflers:
