    RE: composite arf yak?

    Regarding the aileron/elevator horn positions. I don't know if it's a height issue or lateral positioning, but it might be easier to shim the servos to one side to offset a lateral positioning issue. You may also be able to use a ball link of the servo side to offset the linkage enough for a clevis to line up on surface horn. You can't use a ball link on the horns. They break that way.

    You could prolly talk me into buying those parts if you still have them.

    Hi Guys

    I realize this is an old Thread but here are some Baffel photos.

    My Engine Builder buddies swear this is a must.

    RE: composite arf yak?

    The issue that I'm seeing right now is two-fold. a) from the pictures in the CA manual - the hinges are way too far forward, that is, the centerline on the hinge point do not line up with the rotation point (ie. the rod). The manual is misleading on this. b) The second issue is the height - the manual indicates the following:

    "Trial fit one horn in the milled slot, so that the hole for the clevise is between 22 - 24mm from the bottom surface of the elevator, and exactly perpendicular to the hinge axis (the centre of the aluminum hinge tube). Adjust slots as needed...."

    Now, I didn't originally build the plane, but I sure wish CA would supply the templates for this!

    RE: composite arf yak?

    Its not that difficult to make one yourself, just make sure the horn attachement point is over the hinge line.

    RE: composite arf yak?

    BaldEagle - your picture looks pretty much like what I saw in the manual, with the hole in the control arm located above the gap - but I don't believe that it is the right location. Shouldn't the 'hole' in the control arm be exactly perpendicular to the hinge rod - which in the Yak is quite a bit back from the gap)? Yours looks way forward of that point (this was the point I was trying to make).

    RE: composite arf yak?

    I'm not sure if it's supposed to be above the gap or the hinge rod, but I don't think it matters that much. What is more important is that both elevator horns are in the same location.

    It is also important that all four aileron horns are equidistant and perpendicular from the hinge line.

    RE: composite arf yak?

    He depicted an aileron, which does not have a hinge rod. It has a "living hinge". There you align with the upper hinge line.

    Why not try the elevators first. You have to install elevator servos either way. If it works acceptably well, leave it alone. Worst case, glue and screw a forward extension on the existing horn. The instructions on how to make the alignment jig along with a picture are in the manual. No one else got a pre-made jig either. Without using one you don't have a clue what the horns line up with.

    RE: composite arf yak?

    I am setting up my 2nd 2.6m Yak because I sold the first one and after a couple of years I really missed it.



    Original setup:



    DA 100 on stock exhaust, Beila 28x10

    (1) 5945 per surface except for 5735 on rudder (changed to a 5995 when they came out)

    (1) 700 2 cell li poly on ignition (no regulator)

    (1) 4 cell 1200 li Ion reduncy pack, (no regulators) (originaly a 1200 2 cell li ion pack but ended up using a 4 cell pack to move the CG back)



    This plane was amazing!!!!!!!!!!!!!!! Mine turned out nose heavy but the 4 cell pack fixed it, and was solid as a rock on control surfaces



    New setup:



    ZDZ Super 80 with canistor muffler, PT 26x10 carbon prop w/ carbon spinner (engine I have layng around, only needs a 1/2 spacer)

    (1) 5995 per surface (I love these servos)

    (1) 4 cell 4800 li Ion reduncy pack to run both ingition and rx (no regulator) from a single battery (got to love 2.4 to take the noise out of the system)



    Thinking of using a 24 oz tank instead of the 32 oz because this Yak only flies so fast, so more throttle does not make it go any faster, so most of the time I was at 1/3 throttle or less and always landed my old one with half a tank or more. ( you definately will NOT get the speed of a Extra out of this plane, these are SLOW flying planes)



    Really looking forward to another Yak 55SP!!!

    RE: composite arf yak?

    Hi Skymaster,
    To properly tune them, you'd have to set the engine up on a test stand with a way to quickly adjust the header length. Don't worry about it -DA has done the work for us. Just use their header, full length with about 1/4" coupler gap to the pipe. You'll have wicked power. I've never been totally happy with the mid-range, but the top end makes it worth it.
    Enjoy,
    Dan

    RE: composite arf yak?

    Hi all,
    I know this is an old thread but I just ordered my Comp-Arf 2.6 yak (fantasy scheme) and I was wondering if anybody has used a DLE 111 in there yak? I have yet to decide on standard mufflers or full length carbon tuned pipes. I know the cannister tunnel is to short for full length pipes but it might actually be easier to install the full lenght pipes because you can get to them (and support them) where they come out of the tunnel into the fuse. Just wondering how the DLE would run with the full lenght pipes? I'll probably use today's super torque servos thruought on this plane (one per ail) along with the modern 2.4 technology we have today. Not sure about battery's yet but I like to keep things simple and light.

    RE: composite arf yak?

    Only advice I can offer is on the batteries, use two cell A123's for the Rx and servo's, no need for a regulator and can be quick charged on site without taking them out of the fus, I have been using them on all my airframes including jets for over five years without any problems, even use them on the ignition on my MVVS's.

    Marc,
    i build them for living and i got few YAK's with the carbon tuned pipes. you just need to make a nice holl at the ent of the tunnel
    i would use JR 8711 one for each AIL and them have 2 of them at the tail for the radder.

    if yuo have any Q's call 301 257 9888

    RE: composite arf yak?

    You may need to contact one of the comp-arf representatives. Somebody has shown me that the original standoffs are multiple 1/4" thick alum "washers" and you stack them up to the proper length. The plane could be tail-heavy and you could add more washers to balance it out.
    Where facts are few, experts are many.

    RE: composite arf yak?

    I have 2" standoffs. This spaces the spinner backplate about 1.6" from the front of the cowl. This large spacing helps with the balance, especially when using tuned pipes I also recall that a larger spacing was recommended by Quique on his Yaks to increase thrust. Some might find it unpleasing to the eye...
