All ER Tanks are pressure tested for integrity before shipping.  No welding is required by the customer.  (Some images may depict ER Tanks during the fabrication process, and may not represent the finished product.)

ER Tank Systems include a SAMPLE Flight Manual Supplement and recommendations for testing and transferring fuel.  However, it is up to the owner/builder to perform proper flight testing, procedures, and insure proper in-flight ER Tank operation.

See the "Benefits" link from the horizontal menu bar above to learn why ER Tanks might be an excellent addition to your RV-6.

Aerobatics:

Aerobatics are NOT authorized when ER Tanks contain ANY amount of fuel.  Owner/Operator must stay withing Van's recommendations for aerobatic flight.  We have NOT conducted Spin Testing with ER Tanks, as a result, we DO NOT recommend spins in aircraft equipped with ER Tanks

Things to Consider:

If you're contemplating the installation of ER Tanks in your RV-6, you should consider purchasing a "Bung Kit".  Select the "Bung Kit" link from the horizontal menu bar above to learn why this might be a good idea.

Installation:

ER Tanks must be installed in a completed wing.  If you install the tanks before the wing is finished, you may not have access to buck the wing skin rivets.  Of course, it's more efficient to install ER Tanks in a aircraft that's under construction but they are intended to be easily installed in flying aircraft, too.  I would estimate 25% of ER Tanks sold are installed in aircraft that are already flying.

Allow three full days for installation.  If you're aircraft is still under construction with the wing root fairings and wing tips removed, and no worries regarding paint, you're installation will go a little quicker.  However, nothing about installing ER Tanks is difficult, it's just takes some time.  For the most part, ER Tanks can be installed by one person but there are a few "moments" when having two people can really speed the process.

ER Tank Kits are very complete.  About the only thing not included in the kit is Pro-Seal.  You'll only need a dollop (about the size of a golf ball) for the entire installation.  If you don't have any, check with builders in your local area or put a request out on one of the online forums.  (Make sure it's not expired) 

Installation Services:

If you're not up to installing ER Tanks yourself, HWA offers installation services.  For more information, click on the "Installation" tab of the horizontal menu above (Under "Fuel Tanks")

How to Order:

Due to the popularity of ER Tanks, and the expansion of our product line, there has been a backlog for ER Tanks for quite some time.

Wing Tips: 
 
Two seat RV's have been produced with 3 different types of wing tips. We need to know which ones you're installing on your aircraft. I'll do my best with verbal descriptions, but I've attached an image to help clarify the issue.

The 3 types of wing tips most common to the RV-6 are:

1. "Old School" - These are the original tips provided in the original RV-4 and RV-6 kits. The "old school" tips are flat on top, essentially extending the upper wing skin to the outer edge of the wing tip. The bottom surface of the fiberglass wing tip curves upward to meet the straight upper surface. The outboard edge of the wing tip runs parallel to the tip rib of the wing.  (The other two styles taper)  There were no factory cut outs for the lights (that had to be done by the builder)

2. Van's part no: W-715: The bottom of this wing tip is flat and the upper surface curves downward. The tip also gets wider as you move aft along the tip rib. These tips were originally introduced on the RV-7 and give the aircraft a slightly longer wingspan, as well as a "bat wing" appearance. The most distinguishing characteristic is the curved trailing edge as shown in the attached image.

3. Van's part no: W-715-1:  At first glance this wing tip resembles W-715, but it has a straight trailing edge. It also has a larger cut out area for mounting landing and position lights.

The first step is to compare the upper surface of the tips. If it's flat, it's "old school". If it's not, it's one of the two shear tips. The attached image will show you how to quickly determine which tips you have. If you have any problems, please don't hesitate to contact me. We want to be certain since ER Tanks are not interchangeable with the different wing tip styles.

Dimensions:

RV-6 ER Tanks have a critical dimension.  We can build ER Tanks so they fit aircraft "built to plans" but we prefer to build them to fit YOUR aircraft.  The difference is an easier installation and a perfect fit.  The dimension we'll need is the distance between two nose ribs.  You will be hooking your tape measure to the inside of one lightening hole and measuring to the same location (lightening hole) on another rib.

Which Lightening Hole?

The first lightening hole FORWARD of the main spar.

Between which Nose Ribs?

Measure the distance between the FIRST nose rib OUTBOARD of the main fuel tank (be careful, there are two closely spaced nose ribs here.  Make sure you latch the tape to the one closest to the main fuel tank.) and the OUTERMOST nose rib on the wing. (wing tip nose rib)  Note the measurement and move to the other side of the aircraft.  Once complete, email the left/right dimensions, along with your wing tip type, to CustomerCare@SafeAir1.com.

Is this Difficult?

No, only the wing tips need be removed for this measurement.  Use the widest tape measure you have. It will stay erect at greater distances and make the job a little easier.  A good flashlight or drop light is all you need.  The main fuel tanks can remain in place for this operation, though they will require removal for the installation of your ER Tanks.  With a buddy helping, I would expect the measuring operation to take less than an hour.  Running solo, maybe an hour and a half.
