UM,
You are doing everything right as far as I can tell from your post. BUT...there is no real definite answer to your question.
Practice SOMETHING every time you fly. Practice what you are bad at first and what you are better at second. Always fly with a point, and don't listen to advice from people who can't fly....there are lots of them, and most of them think they can fly.
Fly as often as possible with people whom you consider 'out of your league'. Make freinds with superior, (far superior), pilots and ask LOTS of questions. Usually, the best pilots are the ones that the people who can't fly, complain about the most. You will need to learn to take a bit of heat for trying to improve your skill set. It's just a fact.
I have found that the best way, for me, to improve my skills was to fly every day. That is difficult unless you get a foamie. SO...I got a CR-1 from
http://www.chargerrc.com and flew it every day for a year. I fly only gas and foam now, but I still have some glow planes. I still fly foam every day, even on the days I fly my larger planes. It's very convenient, any park, vacant lot, schoolyard, farm etc. will do. This November will be 2 years since I soloed and I have flown SOMETHING glow, gas or foam 5-6 days a week for most of that time.
Pretty soon you will be flying scale aerobats with gas engines and digital servos....this is how we get you hooked.
BTW, as previously noted, you will find KE much easier with more power, more side area and more rudder.
Get a foamie, fly it every day and practice SOMETHING every time you fly. It's that simple. GOOD LUCK!!
