Yep, a pre flight inspection would have saved my last yak crash. I goofed up a landing recently on my addiction, it doesn't look like any damage but I'm gonna take the cowl off and inspect everything closely before taking her up again. I've learned my lesson the hard way, a bit costly too!

Looking from BEHIND. Right and left are always as if you were sitting in the cockpit.

I couldn't help but laugh, sorry about the damage though. I have a cat that does the same thing, all my flip flops are chewed up, the antenna on my dx8 is chewed up but my planes are safe hanging from the ceiling now, the cat just stares at them now. That's nothing though, you oughta see what my German Shepard can do!

Out of curiosity, and because the CZ Yak is my first foamie and has yet to sustain any body damage, how would one go about repairing a missing chunk like that at home? Being a balsa guy, I'm thinking the foam edge might be sanded smooth and then a small balsa block shaped and CAd or epoxied in place. Then some Monokote, Ultracote, dope, or fiberglass and paint to blend it in as best as possible. Are there better materials to use in such a repair?

There is a vinyl spackle you can get from local hardware stores that works well to patch foamies. It's very lightweight and easy to work with/sand etc. I got the tip from a friend of mine in my local flying club. I thought it was funny as I work at Lowe's and we have it right there. I usually pass it 40 or 50 times a day. Also I had a problem with my wire landing gear loosening up inside so I shot a little "Great Stuff" spray foam insulation in there and it has stiffened it up very nicely and has been working great. I put a lot of stress on my landing gear flying from a grass field. The tube that comes with the insulation just fits in the slot the landing gear goes in. Any excess that oozes out can be easily trimmed when it's dry.

Idk, $9 seems much easier lol!!

And instead of balsa, you would shape a foam block and glue it in, and paint it if you were really anal about the looks of a foamy

Could someone take a look at my LG wire in the pics and let me know if it's bent and if so, how? I deadsticked it into a field a couple weeks ago and just replaced the motor shaft. When I had it out today taxiing around the tracking was so bad I didn't take it up. If the wheels bounced up off the hard runway a bit it seemed to grab and pull the plane around, sometimes in a very sharp turn. Felt like I had no control on the ground. Rudder, tailwheel and servos seem ok.

1. are the wheels supposed to be splayed out?
2. is the forward sweep correct?

Thanks!

Landing gear wheels generally have a little "toe in" (front of wheels are slightly angled toward each other) to make the plane track straighter while on the ground. It APPEARS from your pictures that your wheels have a little "toe out" ( front of wheels are slightly angled away from each other) which would make the plane track less straight while on the ground as well as make the steering more "unpredictable". You could try bending the wire SLIGHTLY to get a little bit of toe in. It doesn't need much of an angle to help quite a bit. Also, make sure that both wheels are spinning freely. A wheel that doesn't spin will cause a lot of problems also. Hope that helps...

Looking at the photos you should be fine by reversing the landing gear. As Mugen said you want the wheels to point inwards slightly.

I run my gear with toe out, this way the gear will spread a tad on impact, kind of absorbs shock. If the wheels are toe in it can cause bouncing or gear will shake. I've noticed rc trucks usually have quite a bit toe out, mine does and it tracks perfect and smooth at any speed.
