    Last night I got to work on setting up my Edge for pull-pull on the rudder. That meant loping off the additional control horn I installed and carving out the slot for the new horn (the original horn was glued 95% the way through the rudder). Took 30 seconds to cut the horn I added off with a saw, a piece of covering masked it almost entirely. Another 10 minutes on the drill press has the slot for the horn cut halfway through the rudder, just need to get the horns now and I can finish this up :)

    SO the rudder got a little bit more in depth than I really wanted it to on the Edge. I thought I'd just be able to glue 2 horns into the left side of the rudder and call it good. Well the new horns I ordered were not the same as the original horns so off they came along with all of the wood surrounding them.


    Had to make a new block to glue in place and cut slots for the new horns.



    Slapped some covering over the final product and then cut it for the horns.


    Slung some epoxy on the horns.


    And viola, finished product.


    Tomorrow the rudder servo goes in. I'm going to try it with one servo to see if it's enough power for me, if not then I'll put a tray in with 2 servos.

    Finished up the rudder linkages this morning since I have the day off.



    I know one rudder servo seems like it's not enough but there's 2 things about these servos, 1. They don't blow back, they simply stop moving if the load becomes too great, and 2. They have a constant torque that doesn't fade as the load increases. It should be enough, if not I have a 2nd servo waiting to go in.

    Also got the engine all baffled up. Should stay cool even under my hands.

    I removed a mouse nest from the wing of Hangar 9 Super Cub, now to rebuild the rib and patch covering[​IMG][​IMG]

    I had a similar incident with a friend who gave me a seized up H9 Cub he got from a friend. I reconditioned the engine (OS70FS?), but realized the tail seemed a bit weak. so I took a flashlight and looked into the empennage and found a mouse nest! Little intruder ate the tail structure to make some extra room for his loft. Fixed it up like what you're doing, then gave it to a new member, to pass it along to the next guy... he never gave it up! Flew pretty good! One wheel landings were a cake walk with it.

    More stick time on the Edge yesterday. I let an old school TOC guy take the sticks for a minute to see what he thought, said it needs more right thrust and a little up thrust so I will shim the engine a little to the right and a little to the up- the CG itself is nearly dead nuts. Also, the rudder servo was plenty of torque but the geometry is just not quite right, still very sensitive at center. I'm going to drop to a 3" SWB offset double arm and set the 2nd rudder servo up just so I have copious amounts of torque. Also I think I need to reduce the throw slightly, 45* seems to be overkill.



    SWB 3" offset dual arm and SWB 1.5" single arm ordered up from NorthWest RC, should be here by mid-week :)

    Ok Exprss to shim the up and to the right is easier said than done. I have tried to do this but as soon as you start shimming your spinner is out of centre. Then you have to re drill all the holes in the firewall. And it always ends up like half a hole. Very interested to see how you are going to do this cleanly. And still end up with motor mounted property. Please keep us informed.

    I just added a thin washer to 3 of the mounting standoffs between the engine and the standoff, the spinner is just ever so slightly off center if you REALLY look for it, but otherwise it's unnoticeable.


    I also added my 2nd rudder servo, still waiting on SWB arms from NorthWest RC (actually USPS).

    That looks great you will never see that amount I would not touch a thing.
    Looking at the rudder servos they are not the same should they not be .
