March 26 - completed Right QB Wing

Finished fitting wingtip and also installed flap - on the flap I had to tweak washers to relieve some binding of the brackets.   Will move wings to storage in the next couple of days.

March 25 Update: Wrapping up QB wings

Since last post I've completed prep of the outboard bottom skin (deburr, dimple, scuff, prime) and today I completed installation of this skin.

 I also fitted the wingtip and completed installation of 1/2 of the nutplates.

Not much left to to on this wing!

After completing this wing, I'll move wings to storage and bring tailcone back into garage for joining up with fuselage.  This will be followed by completion of remaining steps in fuselage kit (flap motor, baggage floors, roll bar, baggage bulkheads.

I ordered finishing kit today - hopefully will get here "just in time" as fuse is being completed.

March 20 Update: Wrapping up right QB wing

Yesterday I completed installation of the aileron trim.  First, I removed the aileron pushrod from the wing after marking center position of the trim arm, and riveted on the brackets to hold the trim springs.   Then I re-installed the pushrod and attached the springs to the arm on the trim assembly.  This was much harder than I expected:  the springs are very taut and the space to work in is TIGHT - it helped to remove the assembly from the wing access plate.

I also prepped the bottom wing skin after cutting/deburring and match-drilling the j-channel stiffener: both are ready for priming.  Waiting for some better weather to get to that.  Once done, all that's left of the right wing is wingtip installation and nav/strobe lights. 

While waiting, I've started prepping parts that will be used in my next big phase which will be joining fuselage and tailcone.

Update March 18th - Right wing systems

Since last post I've prepped a lot of parts to do the aileron trim and autopilot servos in the right wing.  I completed installation of the right wing autopilot (roll) servo and most of the installation of the aileron trim.    This includes cutting tubing, drilling and tapping this tubing to fabricate pushrods for the autopilot servos.  Kind of fun but time consuming as are all things airplane.

One part I decided to change on the autopilot was the micro molex connectors supplied with the kit: these have been troublesome for many folks so I am replacing in most places with dsub connectors or Deutsch DTM connectors.

I initially modified the aileron trim bracket's molex connector slot to fit a 9-pin dsub, but when I connect this way there's not enough extra wire length to connect the aileron trim springs.  After I install the springs (need to remove the aileron pushrod tomorrow and attach brackets for the springs), I'll re-evaluate.  However, it won't be a problem using the wire as shown in photos here  - they'll tuck right out of the way.

March 17 Update - continuing work on QB wings

Since last post, I've done the following:

• installed aileron and flap gap seals (R Wing)
• installed all aileron components (pushrod tubes, aileron bellcrank, torque tubes, etc.  (Right Wing).  Adjusted pushrod lengths to get everything place using templates and measurements
• Right wing:  removed two universal rivets at inboard aileron hinge bracket that interfere with aileron movement and replaced with countersunk rivets.  These rivets are part of an SB for the aileron hinge bracket.  I also did the same on these on the left wing.
• Completed wiring in right wing including molex connector for pitch servo.
• Completed installation of conduit and wiring for possible future magnetometer in right wing (either as a 2nd or moving primary there if there is any interference).
• Installed Garmin GMU22 magnetometer in left wing inner bay (using kit from Vans that adapts this to the ADAHRS bracket)
• Installed round connector using wiring harness wires to connect to GMU 22

Right wing is coming along nicely - in the next couple of days I'll order finishing kit and hope to finish this wing in next 1-2 weeks.  Biggest job will be installation of the roll servo in the right wing. I'll put QB wings in storage after that and move tailcone back to my shop to join fuselage/tailcone.

I want to have as many avionics components as possible installed ahead of final assembly - I know I'll be doing a full Garmin G3X system so choosing components that I know will match.

March 10/11 Update: Right wing systems

Right wing fuel tank tested, "passed", re-installed on the wing.  All bolts torqued and screws in place.

Started installing wing wiring harnesses and conduit: I'm going to run enough wiring through this conduit to support either GMU-22 or GMU-11 magnetometer: my current plan is to install GMU-22 in left wing in the position provided by Vans.  If this proves to be problematic I'll switch plans, and will have wiring in place. 

March 6 Update - QB wing, right

I had only a couple of days at to work since the last post:  since then I've removed the fuel tank from the right wing and installed the fuel sender.   As with prior wing I had to modify the bend of the sender float arm.  I also found the resistance to up-down movement of the arm to be more "stiff" than I'd like.  I found the identical part (It's a Stewart Warner automotive style sender) on Summit Racing (where I buy primer) used it - resistance is just right.

I used my Amazon-bought endoscopic camera ( https://www.amazon.com/gp/product/B075ST873B/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 ) to check position of float in the "up-down" directions.

Then used sealant per KAI to final-install the sender.
