Great Iam glad your at it again it's addictive
My tele 40 has a 46 in it a flies good, short vertical this plane if build at 6 lbs typ weight then it will be perfect to learn on with the OS 35 try a 10x5 prop and good to go. The radio I would today.. lean to 2.4 GHz Futaba or Spectrum myself last radio you will need for next 5 planes or forever. The stick build is a little extra work but this plane is a GREAT flier. I also would leave as is as a tail dragger, build to print an it will float.
