CAS J3 Cub *Released 6/13/24* *Marketplace Release 9/12/24*

I always wanted a proper J3 Cub in MSFS and the CAS Cub is better than anything I could have hoped for! I think it might be my favorite aircraft in MSFS at the moment, it feels alive and full of character…just like a real Cub. And I think overall it’s even better than the old A2A Cub!

I just finished a video doing some aerobatics with it above Andrewsfield. It can do pretty much all the maneuvers the real one does flawlessly, like hammerhead turns, spins, loops, one wheel landings, tail-high taxiing and massive sideslips.

I never had that problem. I just did another flight and it shuts down perfectly with the magneto switch.

Same here, it shuts off as soon as I cut the mags. Check you don’t have some sort of binding for the starter engaging by mistake.

I have to shut her down by turning off the mags too. But I don’t understand why cutting the fuel doesn’t stop the engine? Where is the fuel coming from once it’s been cut?

If there was still fuel in the carb it’d run until it’s expelled, but wouldn’t be a long period after cutting the fuel.

There’s still a bunch of fuel in the lines. Consider where the cutoff is, then everything engine-side of that, including the carb bowl. Run up the throttle a bit and it’ll purge quicker. Or just wait.

I’d bet it sorts itself out next time I start the sim. I ran it for a while. I’d bet the POH says not to do that and use the mag switch. It’s one thing to lean an engine out and another to completely purge the fuel as a matter of course.

I’ll have to try to get it out of sorts in mild aerobatic maneuvers and see if it comes out of something you did incorrectly. The only aircraft I’ve flown that has never figured out a way to occasionally ‘break’ the sim and get stuck in some sort of dive or spin is the Deejing RV4. Most aircraft can essentially get knocked out of the FM at times and end in some unrecoverable(but also inexplicable) situation. Usually tail slides and lazy floppy hammerheads. Happens even to the Challenger III. Get them going backwards and the sim has a conniption fit.

It’s worth noting that the aircraft will simulate random failure for the mags to turn off/on

What a challenge it would be to take this Cub across country lol

So, I just wasn’t patient enough. I’ll try to let it sit a little longer next time or run the throttle up. Thanks!

Two scenarios:

I cut the mags and then the fuel. There will still be fuel in the lines the next time I start it up, but I’ll still have to prime the cylinders, right?

I cut the the fuel and let the lines clear until it stops. There is no fuel in the lines, so I will have to prime it considerably more, first to get fuel into the lines and then into the cylinders?

From the manual:

The fuel cutoff valve, located left of the passenger seat, is rarely used in the J3. The engine should be shut off by setting the magnetos to ‘OFF’. Shutting the engine off with the fuel cutoff will empty the carburettor bowl, making restarting the engine challenging. Additionally, it can be difficult to fully open the valve once shutoff without manually aligning the cable.

It fixed itself on the next start of the sim. Tried all the basic aerobatics and some situations it shouldn’t ever be in and it recovers exactly as it should. Love the carb starvation at the top of a loop too. Just outstanding! Visceral enough that 61 knots doesn’t seem that bad of a pace. :smiley:

@CAS Dev
It seems you’re working on a float version of the J3. That’s great news.
If you’re already working on the landing system, wouldn’t it save time and effort to make a ski version at the same time? (The skis don’t necessarily have to be retractable, which should makes the job easier).
With these two versions in addition, all the possibilities of your fantastic J3 would be available.
If I may make another suggestion, it would be nice if the engine start smoke were permanently activated, even when the exhaust smoke is not.
You made a great and lovely plane, thanks for this and your work.

I’m re-creating this flight from Yellowknife to Montreal:

I’m currently about one third of the way…gonna take forever to get there but it’s fun!

**MPH lol like 51 Knots

It is also quite possible to pull the prop from outside the plane (which is what I do).

Note: External Camera View will NOT let you grab the prop.
It is necessary to use Instrument View 0 (Control 0) to be standing outside the plane in front of the prop and be able to grab and spin it. After it starts, Control Space will reset the view, i.e. jump you back inside the plane.

Another longer way to get there is (way cool) type Control 1 (instrument view1). The A key is “Next Instrument View”. So, just keep pushing the A key 9 times and you will walk around the plane and finally arrive at Instrument view 0, standing in front of the prop. And you can grab and spin, (Or you could keep pushing the A key many more times to keep walking around the plane). At any time, use control space to jump back inside the plane.

This is great info! As I read through your explanation, I realized that in over three years with MSFS, I never realized the A key does such a job :joy: Probably MSFS has too many control combinations that are not the most intuitive. That’s especially for planes without a push to start button (by which I mean interactions with components of the plane in the sim).

Can you just bind instrument view zero? Or is there a previous instrument view that shortcuts back to zero?

I find it starts a bit easier if you cog it back a little before swinging it

There is also a “previous instrument view” command to go backwards. It makes me happy to hear of someone enjoying my tiny contribution to Chris’ amazing Cub

Using the previous command was how it’s intended. From Instrument View 1, use “next” to do the walkaround or “previous” to go straight to starting
