Doc,



I'm on the road and don't have good installation photos, but you can see the 

finished product here....the grey, green, and yellow -50 is Will Roy's...I'm 

ferrying the aircraft for him. You can see pics of the plane flying at ARS 

here 

http://www.tvrphotography.com/gallery/thumbnails.php?album=180&page=3e



We did the annual, converted the tanks to "bombs"  (fins, paint), did some 

paint work, etc.   While we did not fabricate the drop tanks or the mounts 

originally, I can tell you that this system needs some changes to be more 

user friendly.  Without getting too technical there are collets on the hard 

points that accept the mounting through bolts.  The bolts go through the 

tanks and are screwed into the collets.   Then is a tiny set screw that 

holds the collet into place, then you adjust the collet to snug it to the 

bracket to secure it in place.  THEN you safety wire the whole thing.  It 

takes about 5 hours PER SIDE to do.  Forget ever taking them off to play if 

you're flying to an event....they stay on, and the plane is limited to 3G's 

in that configuration.



The system does have great capacity (15 gallons EACH), looks great when 

installed, and works very well.  Performance wise, it knocks about 7 kts off 

of cruise speed, but gives you an additional 2 hours of range.  Handling 

characteristics are not adversely affected, except on the ground during roll 

out where that weight outboard makes it just a bit tougher to keep straight, 

but it's perfectly managable.



Based on our experience with these tanks, and our engineering and machining 

capablity, we could easily engineer a much more user friendly system (one 

that could disconnect in about 5 minutes and connect in 30 minutes), but I 

don't know that the demand is there to offset the engineering costs.



I'll be happy to look into it further, if you'd like, but it ain't gonna be 

cheap.



Cheers,



Barry

 Bdog,



 Drop tanks on the 50? When you get a chance, I would like the details of 

 how

 you plumbed it and where are you hanging the tanks. I'm assuming two since

 you post was written as a plural of tank.  Got any pictures?

Barry,

Thanks. Where in Ala is Will Roy basing her. I'm down in Montgomery and Dave

Harcourt is in Birmingham. 

The tanks look pretty cool. The pain in mounting can be re-engineered to

make it simple. I have the fabricators around that can help with that. Got a

couple of other issues to address on the 50 and 52 first before starting to

attach extra fuel. The 50 sips gas compared the 52.

When you guys finishing the engineering, can you work on building a better ass..mine is limited to about an hour in these things! After that, I call work and have them book me a first class ticket. 



I think a centerline tank would look way cooler and I think would require less engineering. I know someone who could knock it out pretty quickly. The same guy who did my bottle set-up....the guy is scary good and we talked in passing about it...his reply "no problem".



By the way, there is a local -52 that had an external centerline tank. Maybe some reverse engineering.......

Tim,

I tend to agree with you. Less plumbling ect. Still have to build a hard

point(s) for attachment which will probably entail removing the exsisting

fuel tanks. If you are going to do that then why not just weld a stainless

steel 10 in section to the ends of the AUX tank. That if the calculation is

correct will get you up to 42 gal total fuel.

Why not pull the whole mess out and put in TWO of those size tanks?

Mark,

I do not think you or I could fit danged shoulders in the hell hole to work

on anything else if two Aux tanks were fitted in the space. I'm not sure one

could get a second tank in that space so easily either.

I really think I could develop a fuel bladder to replace BOTH tanks and add 

another 50% more gas without increasing the area required by the existing 

fuel tanks.

Jeezee! One project at a time! 52 bladders fuel and CO scrubbers along with

contained O2 systems! 

Seriously, A badder in that space in the fuselage would require fabrication

of additional panels in attached to the bulkheads along with manufacturing a

floor over the main spar. As it stands currently, I have a 1.5 hour but and

bladder more fuel in the 50 could really be messy! Have you ever tried to

use a piddle pack in a 50 without an autopilot? Danged it is hard enough in

the Viper.

Just run a relief tub to the exhaust stack. Only good on a stainless exhaust. And be certain that you are the last one in formation. Cheap smoke. Short lived.

Needs a stainless steel injector tip also or it to will corrode. Nothing worse than a corroded limp injector tip in the stainless steel exhaust!

Need to monitor the vacuum gauge on the relief tube to the exhaust stack. Could be a problem concentrating on flying.

 Enough of that, gone to far already.

Six inches! I am not folding it in half for anyone! 



Back on topic...where a diaper. 



I talked again to a guy today about an external, we may get started on a prototype.

Really?  From what I see in mine, I have two different size tanks right

next to each other.  It appears to me that the original aerobatic tank

could easily be made as big as the Aux tank that currently sits right

next to it.  



Dennis is suggesting replacing BOTH with some kind of bladder.  THAT

sounds interesting as well!  



Hey, I'm just thinking out loud is all.

came from an Air Force guy is impressive.

That is what I was referring to. Putting a second aux tank in the acro tank

side on the left side of the fuselage.
