Alternative Fuels (not RealFuels) Discussion
Since at least more than once person is interested, these are hypergolic configs originally concieved of by @Pappystein
The engine list is incomplete.
// LFO to Aerozine50/NTO config
//
// 2.25 to 2.75 is the same as stock's 0.9 to 1.1 so it simplifies engine setup a bit.
// OX:Fuel ratio is 1.97:1 by mass
// Fuel mass per unit (i.e. same volume as 1 LiquidFuel) is 0.0060125 vs LFO at 0.005
// Fuel:Tank mass ratio is 9.62:1, LFO is 8:1
// Fuel cost $604.68 per ton. LFO is $91.80

Those propellants need RealFuels, so this patch needs some ":NEED[RealFuels]" nodes. Ideally this should become part of a new compatility patch with Real Fuels in the future.
Edit: snipped incorrect patch -Jso
Those propellants need RealFuels, so this patch needs some ":NEED[RealFuels]" nodes.
They are CRP resources, RealFuels is most certainly not required, and if anything for completeness they should exclude themselves when RealFuels is installed with a NEEDS[!RealFuels]. RealFuels is much more than resources.
So in my original file I have separated out each rocket family to make editing one section easier.... I have made several additional engines based on existing BDB ones and "filled out" the upper stage engine arrangement with this a bit. A complete list of Hypergolic BDB stages are as follows: Juno-IV 2nd and 3rd stage Able, Ablestar, Delta, FatDelta, Delta-P, Delta-K Apollo CSM mk2 3 and 5 Apollo LEM (both stages). Agena etc. I did not bother with the newest RCS derived upper stages at the time of this file but I may re-visit them.
// Updated CFG to meet R/W Tank masses. Ratio is 2.25:2.75 for Hypergolic fuel. All Hypergolics are AZ50/NTO for purposes of simplcity.

I assume the Hashtag means custom created (non stock KSP or dll created) variable?
eg @PART:HAS[#isHypergolic[True]
Also it appears that for Copied engines that happen after :First, I just add the isHypergolic = True line in the copied data area instead of manually converting each engine during the copy.

It's how you reference variables in a HAS block. :HAS[#isHypergolic[True]] or :HAS[#mass[>1]]vs :HAS[@RESOURCE[LiquidFuel]]
I updated the first post.
Extreme necro, but would @jsolson be okay if I used a derivative of these configs in something else I'm working on?

Go for it
too bad this never went anywhere
It did go somewhere! Pappystein has a patch in the extras folder that does this, I started work on MoreFuels (which is currently abandoned, and probably unfit for use), and it has found a maintained home in the SkyhawkScienceSystem.
@Clamp-o-Tron I love how the SkyhawkScienceSystem fuels are made and work, but I havent found some way to isolate it from the rest of SSS
You could go into the BDB Extras and utilize my Fuel patch (Pafftek/HypergolicBDB). It works, and it is FINE. The only thing I didn't do is expand Hypergolics beyond AZ50/NTO because AZ50/NTO provides a 5:1 ratio change vs. LF/O Fuel, making the math simple. Adding other Hypergolic fuels quickly becomes very complicated, and you start getting into decimal units of fuel and oxidizer that would remain in the tank after the burn.
Of course, this course of action assumes you want to eliminate the rest of SSS.
for the fuel tank issue: could interstellar fuel switch help there?
Or you could just go to BDB Extras and make certain under the Pafftek folder, you have HypergolicBDB installed. If you have that installed and are not using something else that modifies fuel tanks, you will have everything that was created here within.
I utilize it all the time since I was one of the creators.
it was meant as a suggestion for: "Adding other Hypergolic fuels quickly becomes very complicated, and you start getting into decimal units of fuel and oxidizer that would remain in the tank after the burn.", if you would want to do it.
if i offended you, i am sorry
