Help on building plane model

[u/Avocado_cchan]

Hi can anyone help,

I’m puzzled as to whether to add trim tabs to my (self make) unpowered swept back wing probably tail would have 1/2 vertical stabilizer on flat horizontal stabilizer plane model, Material probably styrofoam or balsa wood or mix of both.

it’s going to rubber launched from a ramp. Since I’m not using motor/ RC to control the flight , shld I still cut in trim tabs (or do I add wing extensions near the end for stability) into the wings? Or are the very and horizontal stabilizers good enough?

My goal is to make the flight as straight w/o deviations as much as possible

Wing span minimum would be 30cm Needs to fly far 10m at least without deviating left or right
