Couple Kittens followed me home..

Out with the soggy potato chip..
In with the new Ultracoat basswood.

Elevator with new taller control horn..

And then bad geometry between the horn and bellcrank and well you know..

Didn't like them lead outs anyway..

Well ur taking alittle further I see , i just looked at my control horn and it has the ply. one from the kit on it with one hole and have no idea where the hook up is located in the frame (bellcrank) When you get everything working the way you want would you please give me an insight on how much deflection you have at the elevator .

Funny how things turned into ring around the rosie, but the scratchy feel of the controls and too much throw was going to be a recipe for certain disaster. Now that the geometry and angles are right between the horn and bell crank, it allows the elevator to operate smooth and limp without any bind..off to the hobby robber for leadout cable...

Full down..

Full up..

Moved the hole on the horn twice closer to center pivot..

The z bend area needed polishing to get rid of the flats left by the zbend pliers so it now works like glass..

Lead out satisfaction..

Then the carbon fiber rod in the supply box talked its way in on the plan..
Then you find yourself polishing the end of the setscrew where it will contact the carbon fiber rod..
Never ends.

Well what's the peanut gallery think about a badder tube in front of the main spar going through the 1st in 2nd outboard rib.. This bladder tube that I have is definitely gonna be constricted inside of a 3/4 inch tube.. Will this stuff work squished out like a hot dog?  I understand that people who usebladders claim that it's a no no.. But I'm just wondering if I'm just gonna see a small rich lean condition similar to using Is a classic well tuned metal tank.. Or is it more serious like it goes way lean in flight? Hope some of the experts will perk up and give me some responses on what to do.. Thanks
Joel

Thinking..about more surgery

Thinking too long is overrated..

Don't pinch the bladder. It gives you a false needle setting. Little red caps used to cap calking tubes make good bladders for 1/2a stuff. You can make a plastic bubble by heat shrinking a pop or water bottle over a golf ball, make two halves and join the two halves together to make a ball. We free flight guys sometimes just let the red cap just hang off the plane, but we only carry a small amount of fuel. Just some hints from my combat days. I would also rotate the cylinder head towards the outside of the circle and the needle valve towards the inside of the circle. It will save your needle valve and cylinder and fingers when fiddling the needle.
The red caps are a low pressure set up compared to a tube bladder. Leader line/cable can sometimes be found where you by fishing gear.

Well you have changed the game now , mine is going to need some work before i try fly again I know the deflection of the elv. is way too much compared to yours , Thanks for taking the time to post for me .

Hi Mich,
That Combat Kitten control system is very Nice ! Probable, that we had that that much 'play' in the control, that was needed...
Going from up/down was like putting the brakes on it, and impossible to fly straight.
Tried moving CG fwd, and did not help. It flew straight, if you lost line tension...
Nice Project,
Thanks for sharing it with us,
Are you sure a Cox reedy, really needs needing, a pressure tank ?
I think you should try an easy bladder tank, then see the gains on pressure...
My Cox .049s, just run a nice tank. I like that.
I agree with everyone else here,
Take care,
Have Fun,
Dave,

I'm claiming near airworthiness..

Bladder tube done..I think

Hi Mich,

I would say you are good to go...
Double CA wipe any covering seams.
Make sure,
Up is up, when you pick up the handle...
Got that t-shirt,
Dave
