And it's early days, but with practice and some advice from the forums, you'll eventually have some stuff you can upload.
First thing I'll say is, having the right camera doesn't automatically lend itself to excellent photos straight away. As Nik mentioned above, you're making several rookie mistakes we all made at first.
At this stage I won't throw a huge list of recommendations at you. You have to learn to stand before you can walk, so here is my first piece of advice:
Know your camera, lens and the boundaries in which they both work best
This means that for a set of weather conditions and lighting, your camera, lens will have optimal settings. There's not one rule of thumb, but there are ways you can achieve best possible results.
Here are some simple things to take note of:
1. Try at first to shoot in well lit conditions (with the sun behind you) and use lowest possible ISO
2. If using consumer lenses, try to keep your aperture around the sweet spot of the lens (commonly f8 through f11 is fine).
3. Shutter speed isn't as important (in my opinion) as aperture, but try to maintain a medium to high shutter speed (you don't need to go crazy fast).
4. Try different settings and note what does and doesn't work for you and your equipment
5. Talk to friends who have the same or similar equipment
After you get this right, time to move on to framing the shot. The above shot has two common rookie mistakes.
1. You haven't centred the aircraft - it's too high
2. You haven't given yourself room for error - keep a bit of space around the aircraft, you can always crop later
