Bug - Learstar A1 RCS tanks

[Tarrow]

Looks like the Mk2 Monopropellant tank mounted at the rear of the ship is disabled in the stock ship save file for the Learstar A1.

Caused a bit of a brown-trousers moment when the engines cut out after using 90 of the 390 units of RCS fuel it's carrying

(relevant lines from the craft file, line 2046 seems to be the cause of the issue)

{

name = MonoPropellant

amount = 300

maxAmount = 300

flowState = False <--- This bit here

isTweakable = True

hideFlow = False

flowMode = Both

}

Check it's not activated by an action group, this may have been deliberate

[basic.syntax]

Having flown this and wondered about it... I just checked action groups... mono tank is not listed there, just front winglets and then elevons in various combinations. I don't see an obvious method to enable turning on tank valves by action group. Selecting tanks doesn't display any action group options. The craft has 4 0-10 mono engines; I think the craft designer doesn't want us draining that tank un-aware. If so, that idea should probably be mentioned in the craft description.

I've had a look and that tank is not linked to any action groups that I can see - we've got elevons on groups one through three, winglet toggle on group four, and the expected parts in gear / lights / brakes groups. No action group linked to the solar panels either

Hmm could be a mistake, though most of the stock craft are deliberately broken in some way, this still might be intentional.

It was something interesting I discovered on my own, but I'm not a new player anymore. It's a fairly complex craft for stock, I might be afraid to mess with it when just starting out with KSP. I think the "why doesn't this work" question would likely be encountered on-orbit, not at a critical time of craft operation. It's not "broken" until you activate the stage with 4 O-10 engines, and wonder why you don't get very far.

Hopefully the player notices the upper right resource panel says that it has lots of monoprop, and from there right-clicks the tank. The next big hurdle for a new player, is realizing the red circle-slash icon is a button you can click. (Maybe its covered in a tutorial, I haven't done any of the new ones.)

Some landers descriptions/info tell you that the launch vehicle isn't included; the Kerbal 2 is a "trainer" rocket not meant to get very far. But, the Leastar A1 description is a bit sparse for what it can do: "SSTO is overrated, payload capability and comfortable seats are all the rage these days."

HarvesteR made this craft, he made the Aeris4A as well, that should tell you a lot :/

I learned something from it: it's possible to attach more than 1 SRB, to a single radial decoupler. I confirmed it in the craft file! I have always used one decoupler per engine.

Edit: (The general thought being each part should only be attached to one other part, unless it looks like it's designed for more. I have branched multiple engines on a single decoupler before, by using girders and a quad adapter.)

part = radialDecoupler2_4292713778
