Hi , I am planning to make a low winger this weekend .
Need a plan 

Try a P51D Mustang or an Spitfire designed by "Hans Joachim".

Or if you can choose something other than "Low winger". How about a twin motor Warbird. How about a B25J Mitchell?

Thanks.

We have a big fan of the "Tea Racer"s on our field.  Built out of coro, they are beautiful and fly great (when built correctly!).

And you can build them up to whatever size you want :
