jeffham222 Posted March 13, 2020 Posted March 13, 2020 Seems a bit too much roll--I know the Litening sticks out from the fuselage more and is a bit bigger than an ATFLIR--so it has more drag, but not as much as I seem to be getting. The smallest bit of RWD trim is too much though, it seems. This obviously happens when manually flying the jet, not on autopilot. It isn't drastically dipping my left wing, but it is enough to be annoying and causing me to depend more on the autopilot to flying straight and level. I am more than happy to be told I am screwing something up if I am or at least expecting a rock solid, stable straight flying aircraft when I shouldn't be. Thanks in advance!

FalconPlot16 Posted March 13, 2020 Posted March 13, 2020 Drag always feels weird, even the Aim9x makes a bit much roll.
Raisuli Posted March 13, 2020 Posted March 13, 2020 Oh yeah; put on the pod and there's all kinds of roll. Of course that sounds far more dramatic than it is, but you can tell it's there. Not as bad as asymmetrical Mavericks.
FoxTwo Posted March 13, 2020 Posted March 13, 2020 Are you flying with a 120 or 7 in the opposite station?
jeffham222 Posted March 13, 2020 Author Posted March 13, 2020 Are you flying with a 120 or 7 in the opposite station? Nope, but a -120 shouldn't counterbalance the pod, even in RL I'd assume just based on the two sizes and drag...

FoxTwo Posted March 13, 2020 Posted March 13, 2020 Nope, but a -120 shouldn't counterbalance the pod, even in RL I'd assume just based on the two sizes and drag... What makes you think that?
jeffham222 Posted March 13, 2020 Author Posted March 13, 2020 What makes you think that? Well--and I do not mean to be condescending--my basic understanding of physics. The Litening has much more of a diameter than a -120. Also, the attachment arm the pod has is pretty big (it makes it stick out more than any type of FLIR); part of the diameter of the -120 is "hidden" (for lack of a better phrase) by the fuselage hip or cheek station. -7s or -120s are almost flush to the fuselage compared to FLIR/ATFLIR/Litening/LDT/SCAM pods. This roll behavior--I think--must be a mismodeling issue as I have noticed that a TACTS pod and -9X (or whatever version of -9 is on there) aren't balanced either on the wingtip stations. The approximate same amount of roll is noticeable when you fly the free flight mission in the Persian Gulf map. I would assume the FCS would account for this in the sim, but I guess there is an issue.

I haven't run either through a CFD modeler but logic dictates that an asymmetric load on the aircraft will cause a roll in that direction.

Brun Posted March 13, 2020 Posted March 13, 2020 I'd have thought roll would be caused by asymmetric load, and asymmetric drag would result in yaw. Asus Z690 Hero | 12900K | 64GB G.Skill 6000 | 4090FE | Reverb G2 | VPC MongoosT-50CM2 + TM Grips | Winwing Orion2 Throttle | MFG Crosswind Pedals
SirJ Posted March 13, 2020 Posted March 13, 2020 are you able to counter trim the pod? imo the trim increments are to big to get it counteracted
jeffham222 Posted March 13, 2020 Author Posted March 13, 2020 Brun, you are correct, which is the other thing. SirJ, I agree exactly--trim increments are too much to be useful from what I have experienced.

jeffham222 Posted March 13, 2020 Author Posted March 13, 2020 Well either way, the thing rolls to the left, and it's annoying. Lol... Intel Core i7-6700@3.4GHz EVGA GeForce GTX 1070 8GB 16GB RAM TM TFRP Rudder Pedals TM TWCS Throttle Virpil VPCWarBRD Base TM F/A-18C Hornet Grip
=475FG= Dawger Posted March 13, 2020 Posted March 13, 2020 I'd have thought roll would be caused by asymmetric load, and asymmetric drag would result in yaw. Yaw produces roll. So asymmetric drag will always produce a roll component.
Wizard_03 Posted March 14, 2020 Posted March 14, 2020 Maybe some, but how much I guess is the real question at hand for me. Maybe I am wrong... A lot, the manual has a whole chapter on it. DCS F/A-18C :sorcerer:
