That's a very odd design. The wing is very narrow. What you describe is shaped much more like a free flight world class towline glider. Normal RC glider design would be to make your wing CHORD (length) about double what you have here.

Your tail is MUCH too small even for use as a free flight model unless the fuselage is very long. And I DO mean VERY long.

T tail is not a good idea as it means the fin has to be very strong, and that means heavy, to avoid it breaking on landings. Better for your first designs to stick to low mounted tails.

If you can find a way to show us a top view sketch (preferably to scale) of what you are planning we can offer more help. For most of us our eye is more calibrated to see problems than our minds so a stack of numbers is often difficult to evaluate directly and quickly.

And kudos on doing your own design. For many of us it's what makes this hobby even better than just flying.
