Here are the replies to the queries so far:
Bob T: Yes, it was still positive G's, but the tanks were pretty full yet. And yes, I was about 1800-2000 AGL when they could see it. They saw the fuel spray coming out of the tanks and let me know. So I did another roll looking out the side window (that gets you dizzy quick
) and saw it for myself. They actually said "it looked like it was quite a bit of fuel". I don't think the actual volume is all that much though...it just fans out so much it's very noticeable. By the back of the wing the fan of fuel was probably at least 10-12" wide. I'm guessing with the roll, there is a little bit of centrifugal force that the fuel maybe slightly moves outwards. I'm guessing with much more empty tanks I wouldn't see this. But, I must say I've been seeing a bit of blue fuel staining on my flaps lately and now I know where it came from. The -14 BTW is very nice with rolls. Split-S's were fun too.
woodmanrog, I have the standard RV-14 caps. I don't know what they would be called exactly. They're a mostly plastic cap, that has 2 sections that rotate and lock in. They aren't the expand-to-seal type that the RV-10 used.
The other thing that I don't like about them is the fact that the stock color is kind of ugly. It's somewhat of a yellowish tan color. So this means that you really are forced to paint them. We had a fly-in this weekend and an RV-9 guy came by and wondered why I painted my caps...he said "I tried painting mine at first but they chipped all up like yours are starting to." Well, yeah, mine already have a couple of paint chips in them, especially since they blew off the wing. I painted my RV-10 caps and they chipped up too, but eventually I got some nice engraved ones that have the fuel type and my N-Number on them, and those I left raw aluminum.
Scott, yeah I'd gladly get some heavier caps if I could get aluminum, leave them unpainted and get them engraved. If you have any manufacturer info that you can send me offline or in a PM, I can check with them to see if they offer an aluminum variant. If so I'll go that route. The caps are nice otherwise, and the locking method is convenient. They open nicer than the expand-to-seal types. I also like the pretty anodized neck rings they came with...but I'm hoping for a different material option.
If they don't make them in an aluminum variant, I'll check into having a production run of some top-halves in aluminum. At least maybe that way people could retrofit an aluminum top onto their caps and get them engraved.
No, these aren't like the RV-10 at all. I actually would prefer non-locking caps. I don't need the extra inconvenience of the key or anything, but, if Andair makes one that will fit the -14, I'd consider it. I'll maybe bring some
tape to seal off the open tank at OSH and bring my fuel cap to their booth.
At least we're only a few weeks away now!
I'll try to remember to take some pics and post them so that people can see what they're like.
EDIT: Here is a link to the page on Vans site for the caps we get with the RV-14. They're the T-00007 type.
Also, if you go to the retrofit locking type cap page, it says specifically that they can't be used on the T-00007 flanges used in the RV-14 wings.
So if you build per-plans, you will lessen your options on what fuel caps you can use. But, if you don't go per plans, I don't know if there is any guarantee that the other cap flanges will fit. The RV-14 being all pre-punched, fits the T-00007 flanges. So we're probably going to have to figure out a different solution than most other RV's are using. Ideally, we can talk to the manufacturer and see if they'll make aluminum top halves. If not, I'll have to see how complex they are and maybe make some up like with the axle extensions on the RV-10. If I do it, it'll be a one-time group buy type situation. If I can get the seals to stop leaking though, there will be a limit to how hard I'll try to get aluminum tops. I'd really prefer them, but first I just want them to seal.
