rprachun 0 Posted February 6, 2008 Share Posted February 6, 2008 I have worked on this one most of the day...when flying the new Otter X, the aircraft is constantly pulling to the right. From an outside rear view, the aircraft is rolled a few degrees to starboard in flight. I have zeroed all trims...balanced props and throttles. At a loss. No other aircraft behaves this way (I own all FSX Aerosoft aircraft, plus numerous other purchased planes). If I add about 4-7 degrees of roll trim, I can get it flying straight, but I don't know why it is doing this. Any ideas anyone? (Use full Saitek yoke and two control modules) Sorry...I love the plane but this one has me stumped! Ray Link to comment Share on other sites More sharing options...
Glennc 0 Posted February 6, 2008 Share Posted February 6, 2008 Ray, I saw that too. Take a look at the fuel gauges. The right tank is much heavier. I'm playing the crossfeeding fuel. Glenn Link to comment Share on other sites More sharing options...

Glenn Im new to this plane but from what I see there are no right/left wing tanks, only fwd and aft fus tanks, so it sounds like he has a trim problem. If you put your mouse over the ailerons trim, with tool tips on it will show you the trim setting in degrees, but I'm sure you already checked that. Tryed re-calibrating your yoke? The only other option I can think of is to move a few of the fatter passengers to the other side of the plane :-) Link to comment Share on other sites More sharing options...

What happens when you deactivated the stick? Link to comment Share on other sites More sharing options...
Finn 873 Posted February 6, 2008 Share Posted February 6, 2008 The reason for the right turning tendency is simply weight distribution. Try to remove all passengers (FSX load manager set all passenger rows to zero) and the twotter is flying perfectly straight ! sometimes issues are part of the realisme More comprehensive investigation: With the default loadout of the twotter (load distribution as installed): _____Mid of aircraft___ __________+________ No.__A_____B___C___Seat 1_____1_____1__120_Lb 2_____1___169__110_Lb 3___170___170__170_Lb 4____77___180__180_Lb 5___180_____1__170_Lb 6___180___110__170_Lb ============== Tot__609__631__920 _____Lb___Lb___Lb As You can see, there are 310 Lb´s more in the right side as in the left and the mid row of seats are slightly ofset to the right adding a bit further to the right side imbalance.

Aerosoft Aerosoft Team [Inactive Account] 51558 Posted February 6, 2008 Aerosoft Share Posted February 6, 2008 The reason for the right turning tendency is simply weight distribution. Wothan Or torque? Both props turn the same way. Not 100% sure how this relates to twins (where is Newton when you need him) but in my simple mind there has to remain a torque vector.

MDIvey 0 Posted February 6, 2008 Share Posted February 6, 2008 I can confirm that this is so (weight distribution)... asking the Cabin crew to ask the large Gentleman on the right to move over to the left is going to make a much bigger impact that it would on a 747. Be polite though As to the Torque Mathisj... I guess that is so unless you have you have counter rotating props and I'm not sure if that is so or not on the Twotter.

Finn 873 Posted February 6, 2008 Share Posted February 6, 2008 No Mathjis Try to distribute the weight equally lateral and it is flying perfectly straight. Wothan Link to comment Share on other sites More sharing options...
EDOT-TH 0 Posted February 7, 2008 Share Posted February 7, 2008 Have the same issue... will try to change the weightbalance. Thanks so far for the hint Link to comment Share on other sites More sharing options...
Glennc 0 Posted February 7, 2008 Share Posted February 7, 2008 Yeah, I made the left/right comment after maybe two flights. I didn't realize the fore/aft configuration of the tanks until tonight when I tried to reset the fuel distribution. The description of the power center versus COG also explains a lot of things. I had to compare the Beaver to the Twotter to make me feel a lot better - two aircraft, same sort of mission in many cases, same real world builder and same software developer helped me realize how good the Twotter's flight model is. I am looking forward to the patch and a real avionics switch. Glenn Link to comment Share on other sites More sharing options...
rprachun 0 Posted February 7, 2008 Author Share Posted February 7, 2008 Just want to thank everyone for the responses...I will examine the fuel load...the passenger distribution...and I intend to make the fat lady sing, but she has to do it on the port side of the plane! I am certain this is not mechanical (calibration, etc)...did all that and other twin engine aircraft do not exhibit this behaviour. I will let you know my results.

rprachun 0 Posted February 8, 2008 Author Share Posted February 8, 2008 Just wanted to let you know that emptying the aircraft of passengers (leaving pilot and copilot is OK) solved the right turn problem. Fuel load was not an issue. If I might suggest that the default load-out of the aircraft be pilot & copilot only. Flys BEAUTIFULLY now. Even the "throttle down ... nose pitch up" problem is much less pronounced. I just fell in love with the Otter again Ray Link to comment Share on other sites More sharing options...
Shaun Fletcher 570 Posted February 8, 2008 Share Posted February 8, 2008 Hello Folks, Also dont take a big packed lunch on board and leave it in the spare seat on the other side. When you eat it you'll transfer the weight over!! :shock: Link to comment Share on other sites More sharing options...
