Welcome to the Sonex Builders and Pilots Foundation

ASA Sonex Fly in on May 2nd 2015 in Asheboro, NC.

Great Lakes Sonex Fly In on June 27th at Clow airport in Bolingbrook, IL

We are excited to announce that we will be holding our third annual Great Lakes Sonex fly in on Saturday June 27th at Clow airport in Bolingbrook, IL.

The great news is that our airport is getting a new runway, but and there is always a but, our fly in is going to be a drive in this year. The nearest airport to us is Lewis Airport and pickup accommodations may be possible.

This years agenda includes the following.

Robbie Culver - update on his progress, if not completed Sonex and his turbo conversion of the AeroVee.
Dwayne Hudson from the FAA - discussion of the homebuilt certification process.
Robert Helms of UL Engines presentation on UL engines.

Please RSVP to Al Eidukas

Registration will begins at 8:30 AM 
First presentation scheduled to start at 9:00 AM
Lunch about 11:30 @ Charlie's (separate checks please)
Approximately 1:00 PM presentation

We will close our event with door prizes - you must be present to win.

Please RSPV by June 20th to help us make sure we're setup appropriately 

Hope to see you on the 27th.
Due to an unsolvable scheduling conflict, we've had to move the date for the Mile High Fly-in. The new date is now May 16, 2015, while the location and all other details remain the same. I hope this won't preclude anyone from joining us, and I look forward to seeing you all here!

Fellow Sonex Builders, Pilots and Friends,

I'm pleased to announce the second-annual "Sonex Mile-High Fly-In"! Please
come join builders and pilots from all across Colorado and the Rocky
Mountain region for an afternoon of camaraderie and information sharing.
The event will be held near Colorado Springs, CO, at Meadowlake Airport
(KFLY), May 16th, 2015. Fly-in's and Drive-in are welcome! Arrivals will
start around 8:00 am, and the programs at 10:00am. We'll have burgers and
dogs on the BBQ for lunch.

The presentations will be informal and interactive, allowing current
builders and pilots the chance to pass along what they've learned to
others. Some of the topics will include "Cowling Modifications", "AeroVee
Assembly and Rebuild", "Jabiru FWF Installation Tips" and a review of the
plans and building process.
Several of our local pilots plan to give "Sonex Smile Rides" as a way to
show off the attraction of a Sonex and to hook future builders!
Meadowlake Airport is situated south of Denver's airspace and at the foot
of the Rocky Mountains. It's easy to get in and out, and makes a great
destination. If you plan to stay overnight, accommodations are close by and
dry camping is available on the field.
Come out and support the Colorado Sonex Mile-High Club and make some new
friends in the process! I look forward to a great turnout.

2nd Annual North Central Sonex Fly-In
I had originally selected June 6th for the Sonex fly-in to avoid the local Buffalo Days summer celebration which usually kicks off with a fly-in, car show and pancake breakfast, plus an air show. Last year the Sonex fly-in was the day before the Buffalo fly-in, which isn’t necessarily bad, but it conflicted with a lot of set-up work (our EAA chapter has the pancake breakfast) and other things.
So, with the 2015 date of Buffalo Days set for June 14-21 ( I thought I was good. Wrong!
Other scheduling issues required the Buffalo Days committee to change their fly-in to June 7, so I’m changing the Sonex fly-in date to June 13.
I apologize to anyone who made plans around the old date, but hope you understand and will still be able to figure out a way to come to the Buffalo Airport on June 13.
New date:         2nd Annual North Central Sonex Fly-In
June 13, 2015
Buffalo Municipal Airport (CFE)
Buffalo, Minnesota
Now I’ve got to get back into my shop and keep plugging away on parts (working on wings now. The fuselage is on gear and the engine hanging on the mount). Thanks to all of you who have inspired me to get back on the project!
Happy flying!

From builder Carl Eldridge:
ONEX serial #ONX0172

I just completed the installation of the Stick to Idler Arm pushrod.  I noticed the the elevator would not travel to the full up elevator position.

After further investigation I found the the weld on the elevator push rod was making contact with the idler arm, so using a Dremel Tool I increased the clearance in that area, that was in contact with the arm.  

Note:  I use bright green Torque Lock to indicate that the bolts and keeper nuts have
been torqued or safetied to final spec, this eliminated the worry later in construction "have I checked that bolt?".


This photo was taken with the fuselage laying on its right side for access to the fuselage bulkheads. These clearances must be accomplished before the bottom skin goes on permanently!!

At bulkhead #2 the clearance cut extends into the flange of the cross piece. The width of the factory slot is too narrow for the pushrod, and needs to be made wider for the rod to even be inserted into place. Note also that the snap-in bushing for the rudder cable has been repositioned closer to the outside skin to avoid interference with the elevator push rod.

At bulkhead #3 clearance has been provided at the top of the factory slot, once again the slot needs to be wider to accommodate the push rod.

The rudder cable bushing has been moved to the outside close to the skin to clear the elevator push rod.  The material on the slot is a low friction edge guard I added to prevent the rod from rubbing the bulkhead. 

This looking back at the rear of the fuselage, bulkhead #4 this to show at each bulkhead needs it's on modification to clear the elevator push rod.  Be sure to swing the idler arm thru it's full swing to check clearances. The low friction edge protector is held in place by a dab of 3M black glue.

Bulkhead #5 almost all the way back to the final bulkhead, once again clearance is needed on the upper right side when the rod is in it's full elevator up position.

At our member meeting in July, the idea was raised of a members party at Oshkosh AirVenture 2015. We are planning an event but it must have member support in order to succeed.

We are lucky to have Wayne Daniels as a host for this event, and are planning this as a member-driven event. Translated, that means we need several members to volunteer to assist us. One challenge will be transportation. This is something we need assistance with and have begun working on ideas. The logistics of getting people to the other side of the airport and back is going to require planning but is something I know we can do.

The party will be an informal BYOB burgers and brats affair at Wayne's 7th Heaven over on the east side of Wittman Field and details will be released in early 2015, including a request for RSVP's. The date is tentatively set as Wednesday July 22nd, 2015. The night airshow is a highlight of the week, and we can enjoy it from the perspective of Wayne's backyard. Our plan is to keep costs to a minimum, hopefully around $5 a head.

The Sonex Builders and Pilots Foundation has received the long-awaited letter from the IRS informing us that the Foundation is officially approved under section 501(c) (3) as a tax exempt not for profit organization.

This letter also states that contributions are officially tax deductible and is effective February 18, 2013.Our designation is a public charity.

A message from Sonex Builders & Pilots Foundation:

Greetings all fellow Sonex/Waiex/Xenos/Onex builders, owners, pilots and all those interested in experimental aircraft, sport aviation, and Sonex aircraft.

As you may be aware, the NTSB has been encouraging the experimental aircraft community to improve the safety record of amateur-built aircraft. Type Clubs have demonstrated to have been a significant factor in the overall improvement in first flight, flight testing, and continued operation of E/AB aircraft.

In concert with the above, there have been a core group of Sonex builders/owners who have expressed a desire over the past few months to grow the Sonex community across the nation. What started as one-on-one discussions about bringing more groups together, growing a community, promoting safety, education, and transition training, has now morphed into an informed coalition of individuals who are interested in building a national Sonex type club.

Other experimental and certified aircraft models have type clubs. It is our belief the time is right for a Sonex type club. One glance at the current conversation in the experimental aviation community shows an increased emphasis on many of the topics we have as goals.
We have named this organization the Sonex Builders and Pilots Foundation.

While we have received the blessing of Sonex Aircraft, LLC, this organization has no formal ties with Sonex Aircraft, LLC. All opinions and information contained within are the result of tech counselor, builder/pilot experiences or trusted sources.

Just to be clear, when we speak of Sonex, we are speaking about all Sonex types of aircraft and all those who currently or may in the future build, fly, own, or those who just admire Sonex aircraft.
