I think some need to get a little experience under their belt before thay can even comprehend what a trainer can teach them.
So do you spend time in the T/A, or get some time in the M/A so you can determine what you most need to work on?
We have trainers that are good at teaching the basics and those that are good at teaching the more advanced stuff. Going from the gammet of how to take off, to teaching a split S into a barrell roll defence. So I think trainers can be helpfull at any stage, and are far under utilized by the general aces high population.
I spend most of my time in the TA, normally work for an hour a day mostly with the hog. I have a couple of students I'm working with mostly on tues. and thur. nights (I'm not an official trainer but I enjoy helping others). What do I work on normally myself, mostly stall recovery and pushing the envelope of what it will and won't do. If you push it beyond it's limit enough times it teaches you two things. One, where the limit is and two, how to recover quickly from passing it. Both important in a close quarters fight. I know what I need to work on in the normal MA's, but training can't fix stupid

, becouse that's how I normally get myself killed. Those that know me and fly against me in the TA know I can handle myself in a hog exremely well, so when I die in an aircraft in the MA's it's normally an SA mistake, or I was trying to accomplish the mission (eg. I know there are five fighters over the vbase but I'm dropping that VH with my A20 full of eggs anyway). Or my most likely cause of death trying to save a squaddie who already did something silly. I've had months where I get the 3-5 k/d ratio, but that was a different kind of fighting where I tended not to put myself in poor positions, and tended to come into fights with superior E advantage and always had an exit plan. I don't fight as "smart" now as I used to but I have more fun and am a far better stick now then I was with the much higher K/D ratios of years past. So I'm kinda like my German Shepard in the fact that I know what I should be doing, but I don't alwayd do it. How do I know my German Shepard knows what he should be doing at all times, simple if I put the shock collar on him he does everything perfect (I never even turn it on, battery shot craps years ago but he remembers it from a puppy

).
I just reread your post and I think I took your question the wrong way. I thought you were talking specifically me in the TA or MA, but now that I reread it I think you were going for a general question as to where to learn what you are doing wrong. I'm of the belief that you should learn as much about something as you can before jumping in. So I think spending time in the TA is where you should start. Get the basics as far as dogfighting, following a target with your views, learning what an aircraft will and won't do compared to others, etc, should be the first step. Then head to the MA's, this way when you start to get beat you can better understand why you got beat (if you didn't see how the guy got on your six, it's pretty hard to figure out a counter to it). Also you will be better able to tell trainers what happened and what problem you had. This way they can better teach you how to remedy the situation in the future. There's not just trainers in the TA, people in their run the gammett from noobs to old vets, a lot of the best sticks in the game come in there from time to time, and most are very willing to talk and help you with problems (especially if it is their preferred aircraft).
