DavidNicholas 3 Posted August 7, 2013 Share Posted August 7, 2013 Hi. Taxying the TO: Props full forward, 15% power, gets the plane moving, but soon this tails off and the plane stops. After that, it takes near full power to get it moving, then it starts to move too fast! Backing off the throttle makes the plane stop very quickly, then I have to start all over again. Basically, I have to 'bunny-hop' between 0 and 100% power all the time, just to move. Have had a couple of ground accidents due to not moving and then moving too fast suddenly! Any hints on this from anyone? Link to comment Share on other sites More sharing options...
Deputy Sheriffs Eric Bakker 736 Posted August 7, 2013 Deputy Sheriffs Share Posted August 7, 2013 Hi David, Do you use an add-on like A2A Accufeel? If so, try disabling to see if this helps. After that, you can try to fine tune it. Link to comment Share on other sites More sharing options...
spike9 13 Posted August 7, 2013 Share Posted August 7, 2013 Almost sounds like the brakes are coming on for some reason. Link to comment Share on other sites More sharing options...
FA099Bill 2 Posted August 7, 2013 Share Posted August 7, 2013 You have to give the aircraft enough power to get it moving and then throttle back to keep it going slowly. Do no throttle back to Idle. It is a bit tricky taxiing but eventually you will get the hang of it. Link to comment Share on other sites More sharing options...
Aerosoft Aerosoft Team [Inactive Account] 51558 Posted August 7, 2013 Aerosoft Share Posted August 7, 2013 Keep in mind it also matters how heavy you are and on what surface. But having use close to full-power to start moving sounds like there is something strange going on. Link to comment Share on other sites More sharing options...
Finn 873 Posted August 7, 2013 Share Posted August 7, 2013 Try lsowly to increase power and watch the Torque gauges. Note when it slowly starts to roll. Once it starts to roll, reduce power, but not necessariy to idle, since You probably will need to have a small amount of forward trust to keep going. If You come to a stop rather quick when reducing power, then I would say that something is activating Your brakes. If You use Accufeel, then try to turn it of for a test.

spike9 13 Posted August 7, 2013 Share Posted August 7, 2013 Could it be possible that depending on how the throttle is setup the props are going into beta/reverse and stopping the aircraft? Link to comment Share on other sites More sharing options...
LN-NIL 0 Posted August 7, 2013 Share Posted August 7, 2013 I have sort of the same issue, sometimes I need 40-45% trq to start rolling, but no issue on stopping. And I do not use Accufeel. Seems it's no difference on paved and unpaved surface, but it seems headwind and tailwind have a huge difference on how much torque you need to start moving.

If the controls are well calibrated that should not be possible. Link to comment Share on other sites More sharing options...
DavidNicholas 3 Posted August 9, 2013 Author Share Posted August 9, 2013 Thanks to you all for the replies. I don't have Accu-Feel. The Beta-range lights aren't coming on at all, so it's not a throttle issue in that sense. Maybe it's just a very realistic interpretation of turboprop handling that I have to get used to! I think this simulation is one of the very best I've come across in quite a few years' simming and especially because I do love bush flying more than 'heavy iron' and have been a passenger in real-world Twin Otters many times in Africa - where the plane really shines. As a non-pilot but many-time passenger, the look and feel of this sim really rings true. Link to comment Share on other sites More sharing options...
Finn 873 Posted August 9, 2013 Share Posted August 9, 2013 If Your throttles aren´t setup for reverse trust You can press and hold F2 to set reverse trust. Finn Link to comment Share on other sites More sharing options...
level135 0 Posted August 13, 2013 Share Posted August 13, 2013 Hi everybody, I don.t realy get troubles to taxy this wonderful plane but I feel that she deosn't manage the beta range correctly. Is there any possibilty to set the power throttle to avoid it comes straight from idle to reverse without the ability to stay in beta range ? May be with FSUIPC ?

taguilo 12 Posted August 13, 2013 Share Posted August 13, 2013 Yes it is possible. In aircraft.cfg, I've replaced minimum_on_ground_beta = 0.0 with minimum_on_ground_beta = 12.0. Also I've made changes to the variables that control the Beta lights as to have them illuminated below 12.0 instead of 0.0. IMO these changes reflect a better implementation of the Beta Mode, with better sounds as well. The counterpart is an increase in torque at IDLE that I can live with.

According to Your findings we have changed minimum_on_ground_beta = 12.0 for the next update. But the beta lights should only be lit when entering reverse beta range. This is thoroughly explained in the Maintenance manual for the real Twin Otter. This means that retarding the power lever just until they lit will indicate that You are at 0° propblade pitch, thus zero thrust. Finn Link to comment Share on other sites More sharing options...
level135 0 Posted August 14, 2013 Share Posted August 14, 2013 Thank's for your answer, i'll try this for my next fly and 'll let you know. Luc Link to comment Share on other sites More sharing options...
level135 0 Posted August 14, 2013 Share Posted August 14, 2013 For me it was'nt enough to set minimum_on_ground_beta to 12.0, I had to set my throttle levers with PSUIPC and change my settings in the Saitek programing software, as I use Saitek Pro Flight Yoke. It´s much better now. Luc Link to comment Share on other sites More sharing options...

On the real Twin Otter, those lights do not illuminate between 0.0 and 12.0°. They only illuminate when the propeller blades goes into reverse. ie. from below 0.0 and to ÷15°.

level135 0 Posted August 14, 2013 Share Posted August 14, 2013 I would like they illuminate when the propeller blades goes in beta range, not only into reverse Link to comment Share on other sites More sharing options...
taguilo 12 Posted August 14, 2013 Share Posted August 14, 2013 Finn, That may be true for the 300-series. I have an official Operating Manual but it's for the 100-200 series. In those, Beta Range indicator where blue lights in a round shape, and Manual textually states that "the left and right light illuminates when its related propeller blade angles reach +10° in beta range, and the beta switch, actuated by the propeller slip ring, energizes the circuit to the indicator light". So the reason for me changing the code. But then let's keep as originally coded for this 300 version. Tom Link to comment Share on other sites More sharing options...
Aerosoft Aerosoft Team [Inactive Account] 51558 Posted August 14, 2013 Aerosoft Share Posted August 14, 2013 As always the amount of conflicting information on aircraft surprise me. I got +9 from my documents: I'll discuss this with Finn this evening. Link to comment Share on other sites More sharing options...
Finn 873 Posted August 14, 2013 Share Posted August 14, 2013 Ok.. Reading the maintenance manual again it seems You are right. 9° is the right value according to the FlightSafety Maintenance manual. I will correct for next version. Good catch and sorry for my mistake. Finn Link to comment Share on other sites More sharing options...
level135 0 Posted August 14, 2013 Share Posted August 14, 2013 Great I gonna wait for the next update. Thank´s for all. This plane is lovely, I can't fly another one at this time. Link to comment Share on other sites More sharing options...
