stratman59 Posted October 21, 2017 Posted October 21, 2017 I'm constantly having to make rudder and aileron trim adjustments, If I'm flying at a constant speed and with no wind surely once trimmed it should fly straight and level? I'm using a Warthog and pedals. I have the trims set to the trim switch on the stick. Also after takeoff, I'm having to do manic trim adjustments, watching Wags's takeoff instruction video, he doesn't appear to do any? Even if I try going into 'instant action' level flight I still constantly have to be adjusting.
Art-J Posted October 21, 2017 Posted October 21, 2017 With no aileron trim on this plane, it will never be trimmable for hands off flight, it will always roll a bit. Oversensitive rudder trim (only when assigned to buttons or keyboard, apparently it's better when assigned to analog rotary switch) doesn't help either, though you can learn to somehow manage it by tapping the switch/key rather than pressing it. Undersensitive elevator trim is good for the job though, you just have to wait a bit longer for the speed to stabilize. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.
Magic Zach Posted October 21, 2017 Posted October 21, 2017 (edited) Welcome to the Spitfire. Basically, set your curves, and do things by the book until you have mastered control, then get creative. That's my shortest possible answer...

stratman59 Posted October 21, 2017 Author Posted October 21, 2017 Ah, O.K, so basically it's meant to be like that? If that's the case then fine, I was just worried I was missing something. Thanks
Captain Orso Posted October 21, 2017 Posted October 21, 2017 Well, it's not a question of it being 'meant to be like that'; it's just the way it is. It's like driving on the freeway. Even on an absolutely straight stretch of road you are alway making tiny adjustments to stay in the center of your lane. With flying, it's the exact same thing.

probad Posted October 22, 2017 Posted October 22, 2017 while not perfectly so, these aircraft will feel noticeably more stable only when the correct trim is coupled with correct speed and aoa. any mismatch between your rpm-speed-aoa-pitch will create an unstable state, and trying to trim without first settling on the proper cruise state can find you with a faulty trim setting that will seem correct at first but will have undesirable roll.
BuzZoo Posted October 22, 2017 Posted October 22, 2017 A little bit of right rudder trim helps with the Spitfire constantly wanting to corkscrew left. Though I imagine it makes the plane a bit draggier? I don't really notice myself.

fiddlinjim Posted October 22, 2017 Posted October 22, 2017 Spitfire pilots during WWII mention repeatedly in their memoirs that the Spit needed to be retrimmed after any change in RPM-prop pitch-altitude etc. Advice to set up the engine and then trim is the only answer.
