Just Flight Hawk T.1

if this is cgaviator, its been updated since those videos, i believe

flew in again yesterday, xbox series X. no issues, break into landing worked fine to the numbers.

strange how there are so many different experiences

I think I’ve found the problem:

Firstly, you need to be familiar with the following, taken directly from the current flight model SDK . . .

It quite clearly states that the aircraft’s reference datum position is an arbitrary figure which can be placed anywhere. It even states that if you have the manufacturer’s reference datum position then use it, but goes on to say that most people won’t and everything else will be guesstimates as a result.

Well, we have the Hawk’s ref datum position, as provided by the manufacturer in their maintenance manuals, and everything was built as accurately as MSFS would allow around that. Arms, moments should all have been correct with reference to that ref datum as they were also all taken from the real aircraft’s manuals. That’s how I build flight models - using the correct figures, as much research as possible, all the aircraft’s available manuals and input from pilots but the base is ALWAYS the correct figures.

Working on a very different aircraft, I noticed that the steering on the ground was ‘odd’ - basically, rather than the aircraft following the path put in by the steering input at the nosewheel the rear wheels would slide sideways to cause the directional change. It was almost like a dog’s tail wagging, the rear end had all the movement and the nose stayed where it was. That aircraft’s ref datum position was somewhere forward of the bulkhead. Moving it to 0,0,0 and adjusting all measurements to balance fixed the problem, though it really should not have made a difference according to the document above.

Seeing this thread come to light again today and being massively frustrated with what is being reported, I was trying to think of what could cause it - something I hadn’t thought of or adjusted previously in this flight model. I remembered the steering issue, and adjusted the ref datum position on the Hawk - the actual position is (from memory) a few inches in front of the landing light on the nose, which equates to roughly (for now) 19ft forward of the model centre point. Bear in mind once again that according to Asobo’s own SDK it is a purely arbitrary point and should not affect anything . . .

With Ref Datum set to 0,0,0 and all important measurements roughly (for now!) adjusted 19ft forwards to compensate, i.e. to keep everything in the same relative position, and the handling is noticeably improved. I had seen elements of the issues described in earlier flight models, they are no longer there. I threw together this short and very rough video, which shows max roll deflection and at the same time kicking the rudder, pulling, pushing but with none of the extreme departures from controlled flight:

It’s not going to be an instant fix, there is a lot which appears at first glance to have been affected by this change (such as max roll rate, max elevator effect - you’ll see the most I could pull was 6.9G) and I’m also aware that the engine rpms no longer give the correct speeds, though this has been the case for a while and is not related to the primary issue here, there has been an unannounced change which has affected the engines in one of the SUs since the Hawk was released. Also, I’m currently finishing off the Tomahawk, so I cannot give a timeframe but for the first time in a long time I feel positive about where to go with the Hawk.

Just a shame the documentation is so misleading because when things go wrong, that’s what we look to to try and put us back on course . . .

Thank you so much for your answer.

I can’t follow the SDK chatter. Why should I?
I just expect an airplane that works well.
As a developer, I immediately believe that you are doing everything you can to achieve a good result.

Unfortunately, your company has decided to sell an obviously defective aircraft model as “High Fidelity”. According to the motto: “If it feels totally wrong, then it must be realistic.” And at the highest price too.

Just out of my own interest, I hope that things will turn out well for you at some point. Until then, I still prefer the Goshawk. :rofl:

Best regards

Is it possible to do an engine re-light whilst airborne?

I’ve turned HP cock off to simulate an engine failure.
The RAT deploys as expected.
I then light the GTS and get the green light, then click engine start and get the rotation green light.
However i only get about 10% rpm and when i turn HP cock back on nothing happens.

Am I doing something wrong?

Yeah man!!! I’m glad I persevered!!

Would you be prepared to publish a temporary fix here whilst you work on the Tomahawk and whatever else is more important? A “not OFFICIAL but official lowercase, no support given, no replies given either, patch to get you flying this bird again” fix?

Or DM me and I’ll test it my end and report back whether it solved my main issues. I don’t care about engine RPM. I just want to enjoy this Classic British aircraft again as I used to.

Or maybe you can log some hours and just leave off the “Toma” bit on the job sheet and no one will notice?! :stuck_out_tongue:

Just to remember the good old days:

All the best

will this be changed for the console version?

When I sort it out properly, it will be changed for all. As I said, no timescale but hopefully soon.

Really thank you so much for revisiting these issues. As i said before i dont like to moan about the hard work of developers. I look forward intime to receiving this update.

I think this shows what a few people have said on here, anything over 55% or thereabouts just maxes out the rpm.

What about the external camera? Since update 0.1.8 it’s to close it was perfect before

No idea about cameras, sorry - not my area but I’m sure that’ll be picked up.

Has anyone ran into an issue with the nosewheel refusing to turn on the ground?

I’m aware its supposed to taxi using differential braking with the nosewheel castoring freely, in my case though the nosewheel is effectively welded in place.

I can maneuver on the ground but the jet is fighting me at every step, turning on the spot requires near full throttle and for me to stand on the brakes just to achieve a glacial rate of turn. Parking is near impossible and staying on the taxi-way is extremely challenging.

Did you remove the rudder lock bar?

I have, but it doesn’t make a difference either way.

Update - had a look at the flight model in notepad, found the problem:

Is it like the F18?

Continuing the discussion from F/A 18 nose wheel steering:

No, there is no powered steering on the Hawk, the nosewheel is supposed to pivot freely. Sorted it by changing the code above, for whatever reason Just Flight had the relevant lines commented out in the most recent release.

Just reading through this thread with an interest to purchase on the series X, how is the current build/flight model atm? Recommended yes or no?
