Installing pushrod guides in Tiger 2 Kit
 

I've just completed my first kit build and have a question about the pushrod installation. I glued the pushrod guides into the exit slots as per instructions, but am wondering if they should also be attached to the fuse somewhere near the servos to minimize flex. Right now the pushrods flex a bit at maximum travel for the elevator and rudder, and I could see this becoming a potential problem. I've flown the plane 10 or 12 times, so I know it works as is, but I'd rather fix it before it crashes due to pushrod flex. Thanks for the help! Also for any first time kit builders out there I highly recommend this kit. I am by no means a building whiz and this plane went together very nicely, and flys extremely well!

It would be in your best interest of your plane to get rid of all the push rod flex that you can. It can and will cause your plane problems. Good Luck, Dave

be careful though you will need some side to side give in the outer guide near the servo so the servo can travel without binding. you can always glue in a scrap piece of wood, in the fuse, and glue the outer selve to that.

Here's what jetmech is referring to. And the second picture is worth a look too.

So i ended up taking one of the cutout scraps from the fuse and drilling two holes in it, threading the guide tubes through the holes, and gluing the wood across the former behind the wing. The servos don't seem to be binding with this setup but I'll check it out to be sure when I get home. Also, should I use the pushrods that came with the kit or are there better inexpensive options? Lastly, I put 90 deg bends on the end, drilled out the middle hole on the servo arm, stuck the bend on and put those little plastic pushrod keepers on the other side. I'm now thinking that a z bend would be much better, but I trimmed the pushrods so short that there's no material left. So, new P-rods or stick with the little plastic keepers?

L-bends, Z-bends or clevis's are all fine if properly installed and don't impinge on anything. Keep the unsupported lengths short.
The upper #2 dwg of Minns isn't as bad if you use a wire like in the middle #2 drawing and the end extends into the outer support tube. Not the best but workable. Just run the wire all the way into the inner tube and secure it there.
The push rods should be anchored at both ends and, in most cases, at least once in the middle.
