Great video, just watched it all, lots of interesting things to see. For example my ailerons don't have counter weights ... a Q2 design miss? -- Robert "TheFrisco" Schmid (408)

Robert and Mike--------  Jay sent the link to the video. You should watch ALL of the various videos on the builders. They help to clear up lots of questions and let you decide what you want. Take

I think he is talking about this one: https://youtu.be/mhARVpPf9QA Cheers, Jay

Chris, can you provide a link to your video? I only see three on my end: -- -MD #2827 (still thinking about planning on visualizing how to finish building)

When I get back to Mannford from Boeing OKC this weekend I'll eyeball my Dragonfly canard elevator hinges. I remember only bonded pads on the aft face of the aft "spar". The Canard is a MKII

Was probably this accident. http://n8wq.scheevel.com/documents/accidents/non-fatal/N89WW.pdf

Sam, I believe it was Robert Justin. Kevin

I agree with Sam. Dissimilar electric potential between materials with an electrolyte like dirty water creates a battery. Iron besides rusting has an electronegative value of 1.8 and Al 1.613 a

Always get a kick out of brakes and breaks.

Vern, I do not have Q plans. From the discussion I surmise an Aluminum arm is bonded to the canard and it failed in fatigue between the hinge at the huge change in stiffness where it is bonded in.

No, no, no. The steel is just fine. Just don't keep your finished bird unattended in the elements for 10 years. Do an annual condition inspection, lubricate annually, and the steel tubes will be

Robert--------------  Have you seen all the video of the various builds that Sam has made? There are several of us and some interesting  mods.  I am not saying to do it, but if you watch my video

I was building from scratch so I installed 2  equilly placed hinge points rather than the 1 central one. I have a inboard gear so there is no load on the hinge rather than elevator load . If your

Charlie.. do our Dragonfly Canards share this issue? If so then I'll be modifying. I figured it was fatigue..and probably from propeller thrust variations. Just my guess as to why. First thing that

Thanks Jim Its on my schedule as an annual check item, along with greasing the hinges and checking the pins. I do the check looking for movement at the hinge as a

OK, I get it now. If that works, no new ailerons required. I would only caution again not to get the part too hot. The aluminum will transfer heat directly to the foam and you don’t want to damage

Given my rescue project was sitting outside for a while, some of the steel tubes/connecting rods are corroded and I am inspecting them all. Some of them I had to cut already so I am wondering if

Bad explanation on my part I am sure … Yes we cut the connecting CS11 right at the 1in spacer, and now the connecting rod is stuck inside the aileron torque tube. But I figured we can carefully

Hi Robert, If you are wondering about the original kit parts, you can look at the following document of mine:
