For those interested here are some pictures of the small molded FEJ Viper S tanks. Each tank holds 1300mls.

Also the Skymaster Viper 2.0m kevlar main tank together with the two FEJ tanks.

Plan to run the FEJ Viper S tanks in parallel into the kevlar main tank, then into the UAT.

My guess is your building the small viper ? This blog is for the new L Viper.No worries there is room for both.Just anybody buiding and care to share with us,.. just make sure you mention small or large new or old.

Just ordered an EVO160vx from Chad From Sin City jets (reall great guy).The turbine will be here before the plane [>:]. David when you install your Mammoth lets us know how you like it,.. maybe a youtube video?I will do the same when I get her done.waiting is killing me

Hello , I use self sealing festo valve to connect and disconnect the hydraulic system between the wings and the fusolage. If you don't want to use the Festo valve you can try specific valves produced by Eurokit in Lucca. Best regards

Hi enrico63,
Are these zero loss disconnects so you don't have to bleed the system everytime you remove the wing?

Frank,

There are five fuel tanks plus a uat installed in my Viper. The upper two fuel tanks (upper tanks held in place by former visible in pic # 3)are connected in parallel and flow into the bottom left tank. Bottom left tank flows to bottom right and from there to the main forward tank. I'm sure there's a better way, but this works for me. Don't have the exact capacity of all fuel tanks combined, but my guess is approximately 160 oz. Hope to get the exact amount in a couple of days.[8D]

Yes those valves are not zero loose but self sealing . You must put 2 valves for each tube and a small piece of tube between the valves. So when you disconnect the wings you have only to leave the tube between valves and there is no leacl because the valves automatically close at tube disconnecting. THe valves name is QSK 4 or QSKK 4 for the wall mounted valves. I will post a pic later. regards

Look forward to it.

David I notice you have the Mammoth installed.Have you had a chance to fly it yet? and thanks for the pic's.

No flights with the Mammoth yet. FYI, I just noticed that my Viper wingtube slides completely into one wing half. There doesn't appear to any structure in either wing section to prevent this. This may not be a problem, but I will consider a way to prevent the wingtube from moving once the wing halves are attached to the fuse. [8D]

David,Have you sorted everything out yet? mine will not be here untill Sept .

Frank,

I had a ECU problem that has been corrected with Eric's help. Planning to attend JWM this weekend, if I don't go and the weather permits, I might get some flying done with the Viper.

David

Don't fly that bird untill all is perfect.Wing tubes and ECU.Then post a video

Well gents I spoke with James,My L Viper may be shipping at the end of the month (Sept) So I might get it by mid Oct.We will have a better idea when James gets back from Jet Power.Getting close,I will post pic's when it arrives.
enrico63 nice gear but I think I'm going to have my sent to Down and Lock and have them converted to electric......David you never said had you made out with your ECU and wing tube,hope all is well.

Hey Frank,

ECU has been replaced and a solution for the wingtube was found. I gotten a bit off track as I spend the past few weeks getting a large F-4u ready for its maiden flight. That out of the way now, so looking forward to next week to get back to the kero burners. [8D]

David glad all is good.I'll be chatting with james tomorrow and have a better idea when my jet will be arriving.Heard it was in the paint shop when James left to Jet Power.

Great news,spoke with James today.My jet is in there QC Dept for final inspection.It will be shipped no later than this Monday.I will post pics when it arrives.

Glad you will soon have your Viper. FYI, with the five fuel tanks in my Viper, the total fuel capacity is 208 ounces (minus the UAT).[8D]

i became my VIPER S at Jetpower 2011 in Germany.. some trouble bud i will be there when i solved it..

i will be make a build threat at my www.jetforum.nl !!
