I've got the CA drying now. I've got a little bit of slop in the motor mount so I'm going to take care of that too then hopefully will be able to fly again in about 1.5 hours.

I've got 39 flights on it now so it's doing pretty well.

Did you wedge anything in the hole, or just drip in CA?

I actually glued the wire rod to the elevator instead of just gluing the plastic tubing to the elevator stab. I also held the wire rods in place, then filled the hole with CA. It worked great for me. I figured it would be more secure that way than what the directions said.

Also, here are a few pics of the ply squares I used to secure the cowl with two self-tapping screws. The others are where I used hot glue over the CA on the stick mount.

I re-enforced the motor mount when I first got my plane by using triangular wedges of balsa. The mount was just a little lose so I stuck some toothpicks between the plastic mount and the motor mount and it fixed it right up.

I put four flights on the plane tonight and it flew perfectly!

Mine wasn't loose, but I angled the screw in the plastic motor mount so the prop shaft would fit through the hole in the cowl nice and even...but still allowed for the thrust angle.

What setup do you have in her? Are you using the 450 or 480 motor? I was also able to achieve the correct CG without having to add any dead weight...to include the stick of clay that came with the kit. I may add just a little bit to get her slightly nose heavy, don't know yet. I'm gonna fly her as is tomorrow and make adjustments after that if needed.

I'm using a Park 450 with a 12x6E and a Dynam 20amp ESC. The ESC is mounted up near the the motor. I didn't need any extra weight either and I didn't do the rudder. The battery is up to about the 2nd or so foam bump from the rear and it balances perfectly.

I'm not using landing gear or the under-wing-covers either. I lined the leading edges of the wing, the horizontal stabilizer, and the belly with clear packing tape since I belly flop it.

WOW, a 12x6 prop! How does that work out for you? I too have the Park 450 in mine with a 25A ESC and a 3s 2200mah Li-po.

I went to maiden her this morning, hoping I would beat the wind...no joy. it was just too windy to do any kind of flying. I had the camera ready and everything, but decided it wouldn't be a smart move. Do you have any videos of her in the air?

Here are a few pics that I just took. The first one is where I decided to run the Rx wire, since I wasn't doing the rudder mod at this time. The second is where decided to use self-tapping screws to secure the cowl instead of using the double sided tape that was provided. The others are just "wow, look at me".

Looks great Mike. One suggestion (if I may) is to put some clear tape along the front of the servo wire covers under the wing to hold them in place. They will eventually come loose and I can tell you from experience, it ain't pretty when they do.

Hey thanks Tom! That sounds like a pretty good idea.

Tom, did you have to angle the motor a little when you installed it to the stick mount, so the prop nut would come through the hole in the cowl? Just curious. I had to angle the motor mount for the 450, on the stick mount so the prop shaft would come through the cowl without scraping the sides of the hole.

She came together nicely!

I was a little off center on mine too. I used a dremel sanding drum bit to make the hole a little bigger. There is about 1/4" that you can sand away I think. You can get a little "adjustment" by moving the cowl a little too sometimes.

Do you remember what you did to remedy that? The only thing I could see was to angle the darn thing so it would fit through the cowl. Thanks anyway Tom, you've been a great help with this bird!

Yeah, I had to play with the cowl as well. I think she'll fly just fine though. We'll see...when the damn wind dies down.

Sorry I couldn't meet up with you this morning Mike. Hopefully we'll be able to throw something in the air this weekend.

Yeah, the 12x6E is actually one of the recommended props.

I've got an eLogger and it doesn't over amp the motor or anything. Works very well!

Mike I really like the way you threaded your antennae wire throught the rudder push rod tube. Good idea for sure!

Thanks John. I figured if it was gonna be there, might as well utilize it. Speaking of this weekend, the weather report says 5-10mph winds tomorrow!! I'll definitely be flying tomorrow, so PM or call me and let me know where you want to meet up at. I wanna get out there around 0700-0730.

I think I'll get a few other recommended props and see what I like the best...thanks for sharing friend.

Went out for the maiden this morning with max2112. It got a little windy but nothing too bad. I set her down for her takeoff, then noticed that she wanted to turn to the right. I couldn't keep her straight because I didn't do the rudder mod...yet. I will be doing that soon. I'm thinking that there is too much of a thrust angle in the mounting of the motor. The motor only moves about 1/8" from left to right when dry fitting it. I turned it to the right to clear the hole in the cowl. If I go slow, she will stay straight for the most part, but as soon as I get some speed going, she wants to turn right like the SC. She's already been glued in place. Do you guys think she will be ok to fly? Will there be any serious flight characteristics changes? I tried to hand toss her, but couldn't get a good grip anywhere. I could really use some expert advice right now! I attempted to take the motor mount off, but the head of the screw broke off, and the CA down inside the mount and stick are holding tight, something fierce. Any ideas guys??

Mike,

Have you tried hand-launching? If so, how does she fly on takeoff?

I didn't do the rudder mod, since I fly off a grass field. I also did not want to cut the rudder and have the exposed white foam.

What if you added a servo just for a tailwheel? Like a rudder mod, but different?

No, I haven't tried hand launching her. I can't get a grip on her. I know I will do something about a steerable tailwheel, but in the videos I've seen, she seems to roll out pretty straight. I didn't notice if they did some kind of mod on the tailwheel or not though. Has anyone else had an issue with this bird wanting to go to the right on takeoff, or is it just me??

Re: Hand Launching, I have only done that with a partner. In fact, with my motor setup, it literally leapt outta my hand.....
