You guys.........

Anyway, wasn't there a ViperJet build thread here somewhere with some unnecessary hatches and a bald bloke?....

DENTO

John,
a few picturres from my P200SX install, lots of room!

I'm waiting for an engine mount for the P160 unfortunatley it was missing and I only realised at the weekend, but its been dispatched. so I am hopefully going to attack that soon. Just finished installing and pressure checking the fuel tanks. I have always done this , the only time I didnt, was on my Ultra Bandit, and the centre tank had a leak under pressure (when being filled) and it was a complete N*ts ache to find. I also noticed on mine that the lower tank seam was fowling the fuel pipe hardware. I removed some of the seam and cynoed it to seal it.

Does everyone have their tanks in these positions?? Is this a change to newer kits?

Mine was an early kit and my 'second' tank (the curved one) sits on top of the inlet ducts.

Carsten Groen

Same here Mark,
I took mine with me home from JP (so must be "relative new"), tank also sits on the inlet ducts..

Jim Cattanach

My kit is only about a month old & it came with the upper tank mounting woodwork to fit it above the inlet ducts. After seeing photos of one tank on top of the other, I thought it a better way to do it. Keeps the weight lower & gave me a platform to mount my I/O board & ECU..

hangarman

Chaps,

As "Jascat100" stated mine also came with the mounts, but I decided to keeps the tanks close together for numerous reasons.

Leaves me more room for another hatch.....Jasper!

The tanks are all the same. its just we decided to mount the this way so that I the section behind the cockpit ( Above the inlets ) could be left free for the board with my switches and fill points. As well as keeping fuel lower in the fuselage. I pass this info onto to all our customers and give them the option of doing it this way. ( along with a few other changes and mods, most of which are on this thread by now )
Regards Al

Thought as much. My ply mount was aeropoxied to my tank so I didn't really have a choice

Ali

My Feedback: (5)

Yep but thats because you got a pre production kit LOL

hangarman

Ali,

They moved the hole in the in the top tank, from the front to the top didn't they? I think I saw some installs with that arrangement. I suppose that was to give the option of different placement?


Mark you told everybody you paid extra to have all the menial tasks done for you!!

Duncan

Menial?? they are the bits he was struggling with lol.

Are you going to use the bypass Henry? looking at the photo's of one in stall, it looks as if the main part of the bypass bolts from the underside of the rails, with the lid bolting to the top[&:]???

Jim Cattanach

Yes, the hole in the top allows the tanks to be placed on top of each other & still get the rear cockpit to fit. You do still have to cut about half an inch off the front of the cockpit tub & grind away the excess at the top of the fuz join, to get it to fit with the tanks in this arrangement.

Carsten Groen

Hmm,
I mounted my tank on the inlets (as I saw Mark did it ), I do still have room for the air and fuel fittings on the panel behind the pilot ?!
I know that the fuel sits "higher" in the plane this way, but what are the difference in flight from this, if any (handling) ?
An added benefit of mounting the tank over the inlets (for me) is that there is a lot of room above the maintank for ECU, pump etc etc

Duncan

i think it's just personal preference, they look very neat and tidy sitting on top of each other.

Has anyone tried the smaller version ?

hangarman

I found that out the other day, its not too bad as it only the top bit of the "tub" directly behind the instrument panel so its not an issue.

Duncan I will be using the bypass, Ali has sent me my turbine mount, so I will attacking that quite soon. If you want to talk about it feel free to give me a ring.



Carsten, you will have plenty of room, if you look up Mark Schro. / Ali's install that will give you some good ideas.

Duncan

no worries, i'm off to the masters tomorrow for a building session. Just noticed your avatar !! awesome

Carsten Thankes for the shots very helpfull
I allso sat my tank on top of intake gave more room I thought ,I move my cockpit tubs forword 80mm to give room for fill plugs and bat charge points don,t have to remove tubs for start up or shut down, The plugs you see take place of the switches , Push in for on, Pull out OFF Then female becomes charge Point.


Craig thanks allso went back a bit and seen your install must of missed it

Looks really good! Where did you end up putting your batteries in the nose? Also what batteries did you end up using?

H

Carsten Groen

My install so far, need to get batteries (right now it seems that I will need 3 pcs 2S/5000mA/H LiPo in the nose to get proper CG) and thrusttube installed, and the pilots should arrive in a couple of weeks
The feedline from the UAT to the pump needs to be changed to 6mm all the way (with a small piece of 4mm over the inlet of the pump)
