Wing strut to landing gear .

The bolt that connects the wing strut to the landing gear weldment, seems like it will hit the landing gear when it flexes. Am I wrong ?Continue

Hi David,  all you need is a 45 degree arc on the installed parking break.  To do this simply determine where the valve opens and closes by simply rotating the lever.  Once you know where each of-off is located, pick one (I suggest off) and depending on where you want to mount the brake simple loosen the lever screw to now adjust the lever to match where you will install the brake.  Simple and straight forward.

hows the build going David?  How about an update?

Hi David, thanks for the invite.  Today I finished the build and contacted the DAR.  Week before last I went out to Buzzair in Tennessee for transition training...it was awesome.  I decided to put in a 120 HP Spyder Corvair conversion engine offered by Azalea Aviation and built it there.  6 cylinders opposed dual ignition (electronic and standard points).  I put in 950 hours in my build and enjoyed every minute of it.  I also have WingXPro running off of an I-Levil Technologies 3AW which is mounted right in front of the pilot seat running on an iPad.  This is an excellent set up for navigation weather and ADS-B.  I also dropped in a used Bendix King 76A transponder with alititude encoding and have ADS-B out via the Garmin GDL82.  I have a 2 car garage and built everything on a 4x12 level table I constructed.  Once all the pieces were finished and ready for assembly off to the hanger I went.  If you have limited room you can use a lock and store to keep your finished pieces safe and away from your continuing build.  I am sure you will have a lot of fun building the Cruzer and remember if you make a mistake you can take it apart and get a new piece from Zenith so don’t be afraid to dive in.  I started with the fuselage, then tail feathers and finally wings.  All this was done within 9 months while still working full time but you can take your time and build at a pace that suits your situation best.  My wife was very supportive and really enjoyed riveting so she even got involved in the building process.  Let me know how you are coming along and if you have any questions don’t hesitate to ask.  By the way I chose the Corvair engine for simplicity, weight to power ratio and ease of installation because the fuel injected engines are quite complex to install.  It’s a hard decision to make as the certified engines are ghastly expensive whether aspirated or fuel injected.  Since this was my first build I decided to use the KISS strategy rather than going for all the glitter and gold.  My engine is very powerful and has a 60” composite Sensenich ground adjustable prop and hub.  Looks gorgeous.  All the Best, John
