This is like my 15th Comp-Arf build, a couple more and I should have it figured out I look forward to seeing you and having a little fun!

What no KURTSEITER 3D.COM Stickers? I am so disappointed

My number 1 son and I stopped by last night to get a gander first hand.

What a beautiful airplane!

What is the distance of your standoffs from the firewall including the SWB engine plate?
How far past the cowl does it get you?

[Cracky]

Maybe some CRACKYCANT3D.com stickers would make it look good!!

[Flatlandman]

Ill put one of those on my plane

Well we got a lot done today.... I had to leave Comp ARF headquarters to tend to some family business but Mark was well on his way to finishing up... All is good on the home front. This is going to be one BAd Ass Yak..... Mark should put up some pics later..
Thanks for all the interest.

Most of the wiring is done now, note the wolerine switch and Badger ignition. I'm just finishing off the wiring in the wings. Next step is to ck the CG and move the motor accordingly. I'm real proud of the throttle servo mount. It is a little different but the pushrod has perfect geometry. This has been a fun project that has had few hiccups. I will take some pics of the wing mods tomorrow. I'm also considering redrilling the control horns on the elevators, 35 degrees aint enough

I haven't finished that measurement yet. As soon as I get it, I will post it. I waiting to complete the CG ck and I will move the motor accordingly. I'm shooting for 1.25 inches of prop clearance though.

Is this plane set up for a push/pull rudder system? If not, how hard is it to modify, just some plywood backing or something?

The YAK has a push pull system. Not hard to do at all look back in the thread and you will see the plates Mark made to accomidate the mod. Much better then the pull pull

None of the Comp-Arf planes come with push-pull. They are very easy to adapt it though. Figure out how long of pushrod you need, I prefer a 5" pushrod which will be 5.75" with the ball links installed and bottomed. I then determine how long a servo arm I need. I take the distance between the rudder horns and divide by two. I then set the servo to max throw with the arm on it and measure how far below the servo the arm is. I use this measurement so that the control rod is parallel to the rudder horn at full throw. This will maximize the amount of torque from the servo and prevent blowback. I measure twice then cut the hole in the side of the fuselage. I make a plywood backup plate that is 300% the size of the servo to distribute the load. I use aeropoxy to glue it in, but epoxy would work just as well. It is important to clamp it in position as shown in the pics with a backup plate so as not to dent the fuse. I do this on both sides and then run the servos on different channels. I hope this helps
