C-27J Spartan

So go to aircraft.cfg and change line of:

static_thrust = 1732

for the new

static_thrust = 173.2


Thanks.
 
I noticed a bug with flaps indicator (1.21):

Flaps are on position 1, but shows full too.

And for me model needs better flight dynamics - is too heavy for me. I saw some videos on Youtube and landing looks shorter and start too (requires faster full power), but nice aircraft to explore Antarctica.

Would you like the 1.0 version of the FDE?? 1.2 was modified by someone else but i'm willing to send out the 1.0 to anyone who asks for it..
 
Please email me, webmaster yoyosims.pl I never used 1.00 so it will be nice to test it. Thank You! :salute:
 
Actually, thinking back. I've landed this thing at Lukla, with a pre-release version of the FDE.. I dont think mI ever tried it with the 1.0 release version though..
 
On one of the forums, someone mentioned that the min_throttle_limit = -0.10 should be -0.22 or as in Warchilds 1.0 cfg -0.25. This will give you reverse on landing and let you back up. Keep in mind that the engines spool slow so it will take time after you put it in reverse for the airplane to start moving backwards. That combined with the static_thrust correction seems to make a huge improvement.

Now, in default model for me revers doesnt work. Take Throttle (decrease) for revers (like always for me works exp: DHC-6 of Aerosoft) http://www.youtube.com/watch?v=Kk7d8vQznbk but with Spartan no revers effect. Any tested this -0.22 or -0.25. Is it work?


About this FMD from 1.0 version (Pam). Maybe the best way is to take only lines from engine for 1.2.1 ?

;------------ ENGINES -------------------------------
ect.

with old .air file ?
1.2. has a some of new feautures and improved autopilot.
 
Possibly... What ghappened was that we started working on the spartan some time ago. Then, with the pre beta flight model still in development, work stopped for quite some time. The next thing i know is that the spartan is being released, with some modifications to my fde. among them, the reverse no longer works, even for me..
I've examined the 1.0 config file file and compared it with the original beta version config file.. needless to say, there are quite a few differences.. I'm going back into testing right now and updating the original fde to fit the release, while not losing any original work.. will let you know what happens..

I tested the -0.22 but not the -0.25 and the reverse works. I think -0.25 is the correct number and will start using that. As I mentioned, everything with the engine is slooooooow so don't expect the reverse to just happen immediately, give it a couple of seconds. In my Saitek setup when I pull the throttle all the way back I send a -16384 through FSUIPC to the flight sim so calibration is not an issue.

been working on rebuilding the 1.0 fde into v 1.3 but there are problems.. The first one being that, no matter where i set the static thrust, the plane wants to start rolling at 30 mph as soon as i start the engines.. the second problem is that above 250 knots, something keeps throttling the power and the plane buffets badly.. Plus, it wont go over 250 knots. I suspect a gaugwe, but i could be incorrect.. I'll keep working on it..

Pam,
Thanks for this info! Greate, Today I will fly with this 1.00 FDE and I will give You feedback.

edit:
tested 1.00 + old aircraft cfg.
No, no no. Isnt realistic too. Some better - like ground operation, take off but in the air Spartan dont fly, he swims. In 1.2 Spartan better recives cruise speed. He is more stable. Engine is too hot too fast in 1.0, on the start, on the runway yet. Landing - flaps works like air brake not like a flaps. Too big effect for this. I must land with N1 95% (!), again engines are too hot (yellow labels) on the approach (!), near stall speed. Revers works ok.
1.2 & 1.0 needs corrections but I think I prefer now 1.2 with changes like above in aircraft.cfg. Id like to have only more power for take off in 1.2.

Maybe some chnges in 1.2 :

[TurbineEngineData]
fuel_flow_gain = 0.005
inlet_area = 1.0
rated_N2_rpm = 14267
static_thrust = 173.2
afterburner_available = 0
reverser_available = 1


[turboprop_engine]
power_scalar = 1.0
maximum_torque = 23876 //Based on SHP of 4637HP at 1020 Prop RPM
powerspecificfuelconsumption= 1

?

Tested 1.2 with changes (revers for -0.22) and static_thrust = 173.2. Mutch better.
 
Yep, nice aircraft to explore Antarctica.

thats interesting yo yo.. the best speed i've been able to get with the 1.0 fde is 290 knots. Tharts bout 345 mph or cruising speed on the real bird. top speed on the real bird is 324 knots or 374 mph.. With 1.0 I cant even get close to those..
 
First, I want thank Iris for the generous Christmas sale. It allowed me to pick up the C-27J which I'm really enjoying. I also want to thank the ppl in this thread for the tips on getting the Spartan started.

I don't know if this'll help narrow down the max speed issue but what I observed during a run @ 22,500' this morning is the critical N1 setting is 92%. At or below 92% the aircraft appears to flying as expected but as soon as it hits 93% it behaves like the engines are cut or a speed brake is suddenly deployed. Power/speed drops like a rock. FF was showing @ 161 @ the N1 92% setting ~ just wondering if fuel flow get starved at 93% or something like that? Note: I was testing with an aircraft.cfg file which had the changes to thrust and throttle limit listed in this thread.

More C-27J issues

I stumbled on this thread after picking up this beauty just before Christmas. At $10 it's good. But there are some unfinished flaws, IMO. I've read through the entire series of pages and it's nice to see a possible ver.3 of the FDE. The loss of the reversers is a large oversight.

I'm also seeing weak brakes. I'll taxi the aircraft as normal, 15-20kts, but the engines will begin to "run away" after being pulled back to ground idle and the aircraft will speed up. I've reduced the idle thrust per the thread which helped tremendously. However, when trying to keep the speed down using braking/differential braking, they just don't have the stopping power.

The other issue is the taxi and landing lights. I'm not seeing them light up the front area. Once, I saw a white-ish square box, but nothing like my default or other aircraft.

Just my $.02.

I hope after the Christmas holiday break, some more testing/tweaking can be done.

-Jeff
