    Great ideas -- I'll be tearing it apart when the new servo arrives so I'll check the pins then. Could easily be vibration. Regarding the radio, I used an old model but it only had one mix in it -- which was to spool up the throttle (to keep my electric running). I'll kill that mix tonight...

    Something weird -- I just took the dogs out and thought to turn the transmitter and receiver on. The rudder is back to working. I sat there for five minutes left-right-left-right and it worked the whole time. What the heck? So, just thinking out loud here but: - wouldn't you think if the...

    On the lighter side -- since the da-60 standard muffler has a smoke nipple, shouldn't I be putting smoke in the yak? Is there a simple, inexpensive approach to doing this? Any ideas?

    Thanks! My assumption is that I should be able to pop the arm off the old one, and insert the new one without messing with the cables. Sound right to you?

    He was shipping it Monday, so I'm hopeful. I've already cleared thu/fri nights for the swap.

    Very nice -- something about blue/white/black always looks sweet.

    Yeah -- I'm eyeballing that 100cc Pilot Yak 55..... but would have to get a new car too just to get it to the field :)

    Thanks man. I love the new Russian Thunder too (my wife's Russian). The servo is plugged directly into the Spektrum AR9100 Receiver (no extensions). It's got redundant battery connections which both have a FromeCo 5200mah LiIon attached and also a DC-UP in the extra channel. Very simple...

    Got to the field yesterday... assembled everything; filled up the gas; DA-60 started perfectly. When I went to check my surfaces prior to taking off, the rudder was dead. It came to life briefly but then died again. I shut the motor down, popped the canopy and checked the connection --...

    Won't go maiden until tomorrow so I did a last test on the car-fit and then put her in her garage spot.

    Extreme Flight RC 91" Yak 54 build

    Started the DA-60 for the first time today. No problems except for the ignition battery coming loose. I added another zip tie in the other direction and it all looks good now. No leaks, everything checked out. http://youtu.be/DqUhIMFeLb8 In case you're wondering, YES that is my wife and...

    This should be the last day in the house. We have a rule that once it's started, it never comes back inside. After mounting the muffler from DA... I spent the afternoon carving out the canopy. I am very happy with this muffler already -- found out it comes with a smoke port. Something to...

    Installed the linkage for the throttle servo. The carbon pushrod EF supplied was about an inch too long even with the ends twisted all the way on. Surprising. Attached the ignition and tied up all the wires. Dropped some thin CA in the motor box hatch holes and will attach...

    After trimming ~1/4 in of material off the top and bottom of the firewall opening, I got the DA-60 mounted. Fuel line is connected too. I added a loop so that I could pull the filter out of the motor box for cleaning down the road. Also manufactured a forward facing choke wire.

    DA-60 showed up last night. I was hoping to at least get the four bolts in, but investigation revealed a few things: 1) the pic in the manual shows the carb rotated to put the throttle linkage bottom right. This doesn't work with a slimline Pitts muffler because of the orientation of the...

    A quick note on batteries. I have two FromeCo Relion 5200 flat packs for my AR9000 receiver. I've used FromeCo a lot in the past with never an issue. In this case I ordered them with EC3 and regular JR plugs. The EC3 will stay plugged into the receiver and the JR used for charging and also a...

    Yes -- I have it as you describe. The pic is deceiving because I had a 1-2 inch tail and didn't want to cut it off yet so I strung it back up through a few times and wrapped it around the pull cable. Once a few flights are complete, I'll trim it and it will look better.

    OK -- two day countdown to the DA-60 arriving... In the meantime, I found the lock nuts on the workbench and installed them. ...and got the elevator servos, mpi arms and supplied linkages installed. These savox servos are by far the fastest servos I've ever had. Zander was standing by...
