You need the counterweights. QAC considered mandatory with the Q-200 because of increase in speed. All Q2 kits also shipped with counterweights after introduction of the LS1 canard, but it has nothing

Well my plane was never finished so not sure but mine doesn't have them. Don't judge the dirt, still cleaning her up ;-) -- Robert "TheFrisco" Schmid (408)

I have a few leads on a the O-200 exhaust pipes that cross underneath the engine and have one pipe out the cowling. But I read and heard in YouTube videos that with the straight out exhaust and 2

I thought the mass balancers for the ailerons were “per plans”. Corbin -- Corbin N121CG

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

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
