0003646: UH-60 Blackhawk Advanced Flight Model 0.4.3.1 tail Rotor kicks to hard

Notes
(0006800) JacD (reporter) 2017-10-18 23:17	My feeling is the same.

(0006803) Spinalfirst (reporter) 2017-10-19 00:17	The 0.4.3.1 fixes the major problem of the colective power. also reduce the wind resistance to the frame when flying. The only issue now is the tail rotor input that kicks to hard. even with the tail compensation on. It make the helicopter spin 360 degres at take off and landing procedure. even when crusing you can feel the chopper want to go off track by the tail rotor.

(0006814) Keplager (developer) 2017-10-19 11:39	Please provide a video clearly showing unwanted behavior. I could not reproduce the problem as described. Currently the rotational period of the UH-60M (clean) in high IGE hover is about four minutes (1.5 degrees per second), requiring minor left pedal additions in order to keep the aircraft under directional control. In forward flight the helicopter is very stable and the SAS has more than enough authority in yaw to keep the helicopter coordinated in no-sideslip straight and level flight (not necessary wings level). Also note that most of the helicopters in the mod have undergone complete AFM overhauls, so they will perform differently than before.

(0006821) Spinalfirst (reporter) 2017-10-20 06:41	We manage to get 2 videos of the trouble we got. Made by me and one of my mate on the team. We both compared the UH-60M to another chopper. Myself with the bohemia ghosthawk and my friend with the RHS littlebird. Just to give you a point of view of the difference in the flight patern. Also, as you said.The flight model can differ from the last version for sure. But as you going to see in both video, the tail rotor intend to kick the chopper whatever the manoeuvre we do. https://www.youtube.com/watch?v=cUifpaPb1lk [^] https://www.youtube.com/watch?v=_ugvOfKEhkA&t [^] Plese accept my apologise for my poor english in the video. (we are french) In hope it can help you. We will try more test in our side to see if something might help or be found as the cause. As always we like Red Hamer Studios mods and keep anjoy it.

(0006832) Spinalfirst (reporter) 2017-10-21 00:02	Update. i found something. I dont know if you where using a joystick or a controller to flight. But i found that the trouble only happen when i use the keyboard and mouse to control the chopper. It didint happenned when i used my Xbox contoler. I acctually always fly with keyboard and mouse and i didint though about trying the contoler to see if there was a difference. Try to use the cyclic Foward and backward when using a mouse as cyclic. You should immediately notice the difference with the tail rotor kick. Here is my setup for keboard mouse flying. For the last test i was using only RHSusaf mod. Using a QWERTY keaboard Ciclic foward: Mouse up Ciclic Backward: Mouse down Ciclic left: Mouse left Ciclic right: mouse right Collective raise: W Collective lower: S Left pedal: A Right pedal: D

After several flights (UM-60M) in many aspects there's some issue: * ROLL axis - to sensitive. On extension joysticks is not so hard(but uncomfortable) and could be problem in use standard PC joystic. All stick controls axis should be on the same standard > pitch axis it's ok so roll could be the same. On the ground, wheels brakes off: * PITCH axis - push forward > helo move back and turn right * RUDDER/TAIL ROTOR - push right pedal > move right and forword - push left pedal > turn right and backward(!) During flying forward: * Helo cannot fly straight forward with neutral rudder position. Normal situation is to put very small rudder inputs for correct sideslip heading by wind, bank angle, power decre/incre. ect. Now we need push left rudder at all time almost at the same value like in hover. Conlusion: Helo is still mission capable but with more difficulty. That causes discomfort(AND UNREALISTIC) of standard flight manouvers. I'm completley no idea about mod making (so i have huge respect FOR YOUR WORK) but i know something about flight dynamic of helicopters and in RHS UH-60 things like roll axis is meaby comsetic things but about rudder/tail rotor is difinitely wrong. Testing on AFM with stick, collective(both extend) rudder.
