Default Extended Range Fuel Tanks for RV-10 & RV-14

Sky Designs is pleased to announce that ER Fuel Tank Kits for RV-10 and RV-14 are now available.

Our ER tanks are the same as "standard" but extend two rib-bays further outboard to allow for approximately two hours greater endurance. They allow (optionally) for a second fuel quantity sender in the outboard-most rib bay of each tank. The design also incorporates a "fill-tab" for partial fueling -or de-fueling if you're a "Scrappy" wannabe - to a known level.

Pricing and other details can be found at https://www.skydesigns.aero/products

Very cool! What's involved in installing these in an completed and painted RV-10?

Is this sealing up parts of the existing outboard leading edge for fuel, or are you having to build both the longer fuel tank and the, now shorter, OB leading edge?

Default Retrofitting ER Tanks

Retrofitting to a completed and flying airplane - RV-10 or RV-14 it's the same - requires:

Removing your existing tanks

Shortening the outboard leading edge skin - the kit comes with a drill template for accomplishing this task

Drilling holes in the spar web for the (now relocated further outboard) W-1008 splice rib and the two additional T-1012 tank attach zee's - the kit comes with a second drill template for accomplishing this task

Adding the necessary tank attach screw holes outboard of where the old tank ended then installing doublers and nutplates on the spar flanges - the doublers that are supplied in the kit also serve as drill templates

Building a completely new - longer - fuel tank.

On RV-10, the kit comes with a doubler for creating a fourth W-822 access opening cover on the bottom of the wing. On RV-14, the existing three access openings are enough to access all the places you need to go.

As long as the bottom outboard wing skin has not been installed - as is the case with QB wings - the wing modifications are quite simple but once that outboard bottom skin is on, the "fun-factor" goes way down because access to the spar flange - especially the lower flange - becomes limited. In the case of a finished and flying airplane, we suggest using blind rivets rather than solid rivets to attach the nutplates to the spar flanges.

There are five RV-10 builders at Synergy Air South all adding Ken’s ER tanks. Some of us are already flying and others are getting ready to build their wings - (Tank parts just arrived from Sky Designs so there will be a couple of retrofits and others will be new builds).

The thing that sold me (aside from the extra fuel capacity) was the designer/engineer of these tanks. Knowing that Ken was involved in the original design of the RV-10 put any of my concerns to rest.

I built my wings and original tanks to accept the Hotel Whiskey tanks, but the quality of those tanks seems to have gone downhill, the plumbing is much more complicated and the additional fuel is outboard near the wingtips.

Ken’s design is (as expected) elegant and simple, plus it doesn’t modify the fuel feed system at all. One fuel filler per tank versus an additional cap in the wingtip for HW. He also modified the stiffeners to accommodate an outboard CiES sensor - so you can have accurate fuel quantity from nearly full to nearly empty.

The parts are well made and Ken’s instructions are incredibly detailed and thorough. Although I’m not excited about a couple of days of fun with pro-seal, I am excited about the additional capability this modification will add to an already very capable airplane.

I agree, since I'm one of the first retrofits being done. Sure would have been easier to do when we were building the wings and tanks originally.

Either way, Ken's design is top notch and I think will become a very common option on the 10's and 14's. I really don't see a downside, especially on a slow build wing.

I agree. I have the HW er tanks so I wonít retro fit but it would be nice. Also be nice to have the multiple sensors to read actual fuel level!

I ordered up a set of ER tanks for my RV-14 as soon as I heard about them. Iím a huge fan of long range flying and can certainly leave fuel behind if the flight calls for that. Ken has been gracious with his time explaining the details to me. As a sucker for mods, I pretty much want whatever Ken is offering.

Bingo.

Ken - glad to see you continuing to put high quality parts on the market!
