    AJ Laser 230z 73" Build Thread

    I personally think this setup is great with just a plain old strait arm at 3" spacing. I think the offset look the best, but not needed for this application. I think people call this "Neutral Ackermann". What you don't want is for the cables to be loose in the neutral position, and get tight as...

    AJ 73" Laser 230z After the rudder is cured, Fire up the RX and make sure your rudder arm is moving in the right direction and that it's as centered as you can get it, now you can attach the control cables up, center the rudder, tighten the cables (I found that the crimps I used slid with a...

    AJ 73" Laser 230z Rudder Attachment: Attached the control horns as I previously mentioned. I used a pin to dub on some petroleum jelly so the epoxy wouldn't get into the hinge itself, most regular people use Vaseline... I just didn't have some on hand so I improvised. Then I proceeded to dub...

    AJ Laser 230z 73" Build Thread

    AJ 73" Laser 230z I personally don't really like the crimp quality of the included crimps, so I went with the 15-45lb Berkley fishing line crimps. I used two for insurance, they feel 1000 times better IMHO than their counterparts. If you were to buy new line, I'm guessing it's 45lb or so? I...

    AJ 73" Laser 230z Microballooning it up: A shot sized cup would be a better method for this FYI. It'll keep the glass balloons from going all over the place.

    AJ 73" Laser 230z Control Horn Installation. As you can tell, I scuffed up the lower section pretty good of the control horn along with the underbelly of the plate with some sand paper just like the elevator joiner.. I even made a few notches with my dremel just cuz, heck it probably lowered...

    I used these from Redwing RC (they come in pairs): Elevator - SS-PR-110 (140mm OAL) Ailerons - SS-PR-30 (55mm OAL) http://www.redwingrc.com/index.php?main_page=product_info&cPath=3_6_38&products_id=91 I found that these push rods use up most of the threads with a bit to spare. I just...

    AJ Laser 230z 73" Build Thread

    It's hard to find any aftermarket servo arms that support the Mfgrs ball link ID. The Mfgrs ball links have a smaller OD so they can fit inside the control horn slots, and you can use the servo arms that cam with the servo and wouldn't have to auger out a huge 4-40 hole. I essentially bought new...

    AJ Laser 230z 73" Build Thread

    Makes perfect sense! I've always marked with a pencil and just cut inside the box I made. I like what you are saying about lifting up the horn plate, and using it as a guide as you cut. I usually have enough white ultracote laying around to cover my roof, that stuff is handy. Makes sense to save...

    AJ 73" Laser 230z Horizontal Stab and Elevator: Since I am using one elevator servo, I will be joining the elevator halves together. Doing this, insert the hinges, and joiner, mark the edge with a pencil, remove, scruff the joiner with a fine sandpaper and finish it off with a coarse piece of...

    AJ Laser 230z 73" Build Thread

    AJ 73" Laser 230z Sometimes when you get an ARF you need to make it your own. So naturally you modify it a bit, right? I personally like how the stars on this ARF resemble the scale feature of the original Laser Aircraft. SO at no disregard of the mfgr's original color scheme, which actually...

    I've used Spot on RC V1 servo arms on the ailerons of my 71 slick, and found one that came loose during my preflight. I always use blue locktite, maybe just me, that's why I went with the MPI's... but on the SAVOX servos I had to ream out the hold down screw hole. I could guess this is why...

    AJ 73" Laser 230z I tried a "new" method (to me!) to open up the holes. I used my soldering iron. It can be messy in the larger sections, but for holes it works like a champ. My trusty Xacto knife sat out on the bench for this process. Use a floodlight of some sort to help find the holes. I...

    AJ 73" Laser 230z So I'll just try and play catch up on some pictures I have been taking. First off I must say that making a purchase through Tim Jesky was probably the best service I could have asked for. Since I live in Alaska, it's hard to get this size of flying machine shipped here for a...
